Updating IPCC AR6: still bound for catastrophe

International group of climatologists launch a set of annually updated climate indicators to track human induced global warming through time.

This decade is absolutely critical for climate action if we are to avoid climate catastrophe. However, up to now we have lacked a standardized set of measures of the level of human-induced warming for tracking our progress over times as short as a year.

So far, the gold standard against which progress can be measured has been the IPCC’s cycle of Assessment Reports (e.g., the latest being AR6, completed this year). These have been published on cycle times of 6 to 7 years.

A team of 50 authors from major climate science institutes and universities around the world under lead author, Piers Maxwell Forster of the Priestly Centre University of Leeds, have set out to publish annually updated reliable global climate indicators in the public domain. This is based on the assessment methods used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report, to update the monitoring datasets and to produce updated estimates for key climate indicators. These include emissions, greenhouse gas concentrations, radiative forcing, surface temperature changes, the Earth’s energy imbalance, warming attributed to human activities, the remaining carbon budget and estimates of global temperature extremes. As these measurements are traceable and consistent with IPCC report methods, they can be trusted by all parties involved in UNFCCC negotiations and help convey wider understanding of the latest knowledge of the climate system and its direction of travel.

The preprint of their first update, Indicators of Global Climate Change 2022: Annual update of large-scale indicators of the state of the climate system and the human influence, was submitted for review (open for discussion on 05/05/2023) to the Copernicus journal Earth Systems Science Data.

Although still unreviewed, this work certainly provides the most up to date data on our progress towards reversing global warming while that might still be possible.

The news is bad. Although there are a few improvements in isolation, nothing we have done through the end of 2022 has been enough to perceptibly the rate of global warming.

Indicators of Global Climate Change 2022: Annual update of largescale indicators of the state of the climate system and the human influence

Abstract. Intergovernmental Panel on Climate Change (IPCC) assessments are the trusted source of scientific evidence for climate negotiations taking place under the United Nations Framework Convention on Climate Change (UNFCCC), including the first global stocktake under the Paris Agreement that will conclude at COP28 in December 2023. Evidence-based decision making needs to be informed by up-to-date and timely information on key indicators of the state of the climate system and of the human influence on the global climate system. However, successive IPCC reports are published at intervals of 5–10 years, creating potential for an information gap between report cycles.

We base this update on the assessment methods used in the IPCC Sixth Assessment Report (AR6) Working Group One (WGI) report, updating the monitoring datasets and to produce updated estimates for key climate indicators including emissions, greenhouse gas concentrations, radiative forcing, surface temperature changes, the Earth’s energy imbalance, warming attributed to human activities, the remaining carbon budget and estimates of global temperature extremes. The purpose of this effort, grounded in an open data, open science approach, is to make annually updated reliable global climate indicators available in the public domain (https://doi.org/10.5281/zenodo.7883758, Smith et al., 2023). As they are traceable and consistent with IPCC report methods, they can be trusted by all parties involved in UNFCCC negotiations and help convey wider understanding of the latest knowledge of the climate system and its direction of travel.

The indicators show that human induced warming reached 1.14 [0.9 to 1.4] °C over the 2013–2022 period and 1.26 [1.0 to 1.6] °C in 2022. Human induced warming is increasing at an unprecedented rate of over 0.2 °C per decade. This high rate of warming is caused by a combination of greenhouse gas emissions being at an all-time high of 57 ± 5.6 GtCO2e over the last decade, as well as reductions in the strength of aerosol cooling. Despite this, there are signs that emission levels are starting to stabilise, and we can hope that a continued series of these annual updates might track a real-world change of direction for the climate over this critical decade.

Some of the observations:

The first set of observations shows that most human carbon emissions have not slowed, although, although the slowing economy over COVID have somewhat slowed overall growth (although this appears to have resumed in 2022). The only area where have actually significantly slowed emissions is for regulated fluorinated gases (F-gas).

Figure 1: Annual global anthropogenic greenhouse gas emissions by source, 1970-2021. Refer to Sect. 2.1 for a list of datasets. Starred datasets (*) indicate the sources used to compile global total greenhouse gas emissions in panel a. CO2 equivalent emissions in panels a and f are calculated using GWPs with a 100-year time horizon from the AR6 WGI Chapter 7 (Forster et al., 2021). F-gas emissions in panel a comprise only UNFCCC F-gas emissions (see Sect. 2.1 for a list of species). Not shown in panels d and e are biomass combustion emissions from GFED (Van Der Werf 2017), which are included in the aggregate estimate in panel a.

The next set of figures shows how effective the various gases in greenhouse layer in the atmosphere are at capturing solar radiation (i.e., “effective radiation forcing”). In 2a right facing bars represent a net positive forcing of higher temperatures, while the left facing bars represent the reflection of extra energy away from Earth. 2b shows a fairly abrupt increase in the forcing between 1960 and 1970, presumably due to the increasing annual rates of greenhouse gas emissions. Note: if the Earth is to have any chance to begin cooling the anthropogenic forcing (grey) needs to trend down, not to continue rising higher as it does here!

Figure 2: Effective radiative forcing from 1750-2022. (a) 1750-2022 change in ERF, showing best estimates (bars) and 5-95% uncertainty ranges (lines) from major anthropogenic components to ERF, total anthropogenic ERF, and solar 610 forcing.
Figure 2: Effective radiative forcing from 1750-2022.  (b) Time evolution of ERF from 1750 to 2022. Best estimates from major anthropogenic categories are shown along with solar and volcanic forcing (thin coloured lines), total (thin black line) and anthropogenic total (thick black line). 5-95% uncertainty in the anthropogenic forcing is shown in shaded grey. Note solar forcing in 2022 is a single-year estimate.

Because Earth currently suffers an imbalance between the solar energy it receives and what it radiates away to outer space as heat energy, the difference between energy received and energy radiated is stored as heat by raising the temperature of various components of planet’s mass (i.e., as the heat inventory). Figure 3a shows that the vast bulk is being stored at different water levels in the ocean, with virtually all of the remained represented by melted ice and the surface layer of soil. Again, if we are to even begin to reduce the rate of global warming, the graph of energy change must be changed to a down slope rather than the continuously rising one show here.

Figure 3b compares the IPCC’s estimates with the somewhat higher estimates presented in this paper.

Conclusion

There is absolutely no good news in the vast array of evidence assembled into these few graphs (assuming the work stands up to peer review, which it almost certainly will). Nothing humans have done to date has had a visible impact on the ominous trends into the climate crisis of the 6th global mass extinction in a ‘Hothouse Earth’ that will simply be too hot for many keystone species to survive physiologically. Beginning with Steffen et al’s, “Trajectories of the Earth System in the Anthropocene” and “Tripping down the road to Earth’s Hothouse Hell and Global Mass Extinction“, a series of articles in Climate Sentinel News explains that falling into the hothouse hell will be as easy as falling off a cliff.

As noted herein above, if we are to get off that road to Hell before it is too steep for that to be possible, we basically have to turn the graphs shown above upside down, so the trends are back towards where they were in the first half of the last century. We won’t be able to do this as long as our governments continue protecting and subsidizing the fossil fuel industries that are still making things worse from one year to the next. Basically our governments will have to work together and mobilize a global war against the climate emergency. Individually, as is the case in global war, we’ll probably have to accept rationing of critical or polluting resources and some curtailment of our usual freedoms to make things worse….

It will be hard, but consider this: It took us more about 100 years from beginning in 1927 with 2 bn people and steampunk technology to accidentally warm the planet to its present state. Starting now, with 2023’s highly advanced and incredibly more powerful technologies and scientific knowledge, we should be able cool the planet back to a sustainable temperature.

The first step has to be fixing our political systems so they work for all humans rather than working to make a few vested special interests become insanely wealthy and powerful individuals at the expense of the planetary biosphere.

Summary from the Copernicus ESDD article bringing reported values from IPCC AR6 report up to date at the end of 2022. The causal chain from emissions to resulting warming of the climate system. Emissions of GHG have 1190 increased rapidly over recent decades (panel a). These emissions have led to increases in the atmospheric concentrations of several GHGs including the three major well-mixed GHGs (panel b). The global surface temperature (shown as annual anomalies from an 1850–1900 baseline) has increased by around 1.15°C since 1850–1900 (panel c). The human-induced warming estimate is a close match to the observed warming (panel d). Whiskers show 5% to 95% ranges. Figure is modified from AR6 SYR (Figure 2.1, Lee et al., 2023).

We’re almost out of time to save our species!

The Guardian article shows we’re perilously close to the point of no return where global warming will be unstoppable. The UN says act now! Victoria needs to have a successful climate election as this is the only issue that really matters.

The featured image (from the Guardian article) shows no hint that the rising greenhouse gas emissions driving global warming have even slowed, let alone begun to reverse. In fact, as evidenced over the last three years (shown in the circle) methane emissions are currently accelerating. Over 100 years methane has more than 30 times the greenhouse potential than CO₂ (more than 80 X over 20 years!). Accelerating methane release from soils and permafrost is a highly dangerous source of temperature related positive feedback capable of driving temperatures higher than humans can possibly stop – to produce ‘runaway’ feedbacks forcing Earth’s climates into the ‘Hothouse Earth‘ state within a century or so that would most probably cause human extinction.

We face a real and existentially stark climate emergency. For humanity to have a future, WE MUST STOP AND REVERSE GLOBAL WARMING. Because this is a global phenomenon to have any hope of success, governments must coordinate and lead actions.

World close to ‘irreversible’ climate breakdown, warn major studies

Key UN reports published in last two days warn urgent and collective action needed – as oil firms report astronomical profits

The climate crisis has reached a “really bleak moment”, one of the world’s leading climate scientists has said, after a slew of major reports laid bare how close the planet is to catastrophe.

Collective action is needed by the world’s nations more now than at any point since the second world war to avoid climate tipping points, Prof Johan Rockström said, but geopolitical tensions are at a high.

He said the world was coming “very, very close to irreversible changes … time is really running out very, very fast”.

All three of the key UN agencies have produced damning reports in the last two days. The UN environment agency’s report found there was “no credible pathway to 1.5C in place” and that “woefully inadequate” progress on cutting carbon emissions means the only way to limit the worst impacts of the climate crisis is a “rapid transformation of societies”.

Read the complete article….

However, as dire as the UN’s predictions are, they almost certainly understate the magnitude of the risks. Government action is essential and urgently needed! Where Victoria is concerned we can elect such a government in less than three weeks.

In Australia, state governments probably have the most power to control and stop human sourced greenhouse gas emissions (CO₂ and methane) through licensing, permitting, and regulating (environmental and development). Even though the Andrews Labor Government in Victoria is doing a lot to act on the climate emergency, the voting record and its campaigning shows that Labor continues to support fossil fuel developments that will continue adding yet more greenhouse gases to the atmosphere. This will keep pushing us ever closer to the point of no return beyond which warming will run away to a Hothouse Earth and likely human extinction. This is a very real climate emergency!

Thus, the upcoming State Election gives Victorian voters a chance to shift our government towards prioritizing action on climate change. What we need to do is to elect enough climate friendly independent, minor party and Green representatives in present Labor seats to put climate activists into the balance of power. As demonstrated federally, fossil fuel puppets and other losers will undoubtedly shout to the rafters that a hung parliament is a recipe for chaos and disaster, but recall that in terms of passing legislation the Gillard Minority Government was arguably one of the most successful governments in Australian history.

Vote Climate One shows Victorians how you can use your preferential voting system to maximize the power of your vote to elect a climate friendly representative.

Our Climate Lens Traffic Light Assessment process has determined where every candidate in every electorate stands on climate issues and ranks them in one of three classes: Green Light – trustworthy supporter of a strong climate policy; Red Light – bad climate policy, voting record or other history suggests can’t be trusted to support a good strong climate policy, or position on climate cannot be determined; Orange Light – weak climate policy and/or record but definitely better than those ranked Red Light.

For the Victorian Election, our Voting Guides for each electorate do not tell you who to vote for. However, if you want to elect a climate friendly government, we provide information about every candidate’s climate policies and an easy to follow voting strategy to maximize the chance to elect a person with a good policy.

VC1’s submission to UN’s First Global Stocktake

Vote Climate One submitted Dr Andrew Norton’s 22 Aug. paper, “Recipe for disaster: ‘We are only responsible for our domestic emissions’” to the UNFCCC’s First Global Stocktake.

Dr Norton is a specialist in theoretical physics and applied mathematics who has applied his analytical mind to issues relating to climate change and its dangers to humanity.

The UNFCCC is the United Nations Framework Convention on Climate Change – The intergovernmental body responsible for COP and IPCC processes relating to the understanding of and acting on the ongoing process of climate change.

The Global Stocktake established in the Paris Agreement (GST) is a process for taking stock of the implementation of the Paris Agreement with the aim to assess the world’s collective progress towards achieving the purpose of the agreement and its long-term goals (Article 14).Decision 19/CMA.1 outlines the modalities and sources of input for the GST.

The Vote Climate One submission states:

3.1 Best available science shows that supply-side action is required [Q5a]


The Paris Agreement has been relying on demand-side action (via emission reduction NDCs) to reduce the global GHG pollution rate. The world’s governments have been too slow to respond. Best available science shows that supply-side action to reduce fossil fuel (FF) production is now also urgently required: it is now physically impossible for reductions in GHG emission rates to alone suffice in preventing the climate chaos and catastrophic environmental losses that will ensue if warming is not limited to 1.5◦C.


3.1.1 Planned over-production of fossil fuels [Q1, Q4]


The Production Gap Report [1] — first launched in 2019 — tracks the discrepancy between governments’ planned fossil fuel production and global production levels consistent with limiting warming to 1.5◦C or 2◦C. Key findings of the 2021 report (page 4) include,

• “the world’s governments plan to produce more than twice the amount of fossil fuels in 2030
than would be consistent with limiting warming to 1.5◦C”
• “Global fossil fuel production must start declining immediately and steeply to be consistent
with limiting long-term warming to 1.5◦C”


The question of which countries need to take action on fossil fuel production is answered in the report (March 2022), Phaseout pathways for fossil fuel production within Paris-compliant carbon budgets [2].


From the Headline Finding on page 6: Based on a 50:50 chance of not exceeding 1.5◦C,


• “The report makes absolutely clear that there is no capacity in the carbon budget for opening
up new production facilities of any kind, whether coal mines, oil wells or gas terminals.”
• “A transition based on principles of equity requires wealthy, high-emitting nations to phase
out all oil and gas production by 2034 while the poorest nations have until 2050 to end
production.”

Read the complete submission…..

The bottom line is that:

the Federal Government is still planning to rapidly expand Australia’s FF production and FF exports:

• There are 114 fossil fuel major projects in the Australian Government’s approvals pipeline [4]
• The report (May 2022), “Carbon Bombs” – Mapping key fossil fuel projects [5], finds that Australia is planning 23 of the world’s 425 carbon bomb projects (each exceeding 1Gt CO2).


When Prime Minister Albanese was recently asked why Labor would not consider the Greens policy of “no new FF mines”, the final point he made to terminate the discussion was that the UN, “measure emissions based upon where they occur, not where the product comes from” [6].
Similarly, when Australia’s new Environment Minister, Tanya Plibersek, was asked if the fastest way to reduce emissions wasn’t simply to say “right, no more coal mines”, she was obliged to reiterate Labor’s position [7]:

“We are responsible for the carbon pollution that we emit here in Australia.” [i.e. Our governments have no responsibility for Australian produced carbon that is burned overseas….]

Read the complete submission…..

Both Federal and State governments have many levers available to them that could stop or reduce the production of fossil fuels, irrespective of their claims (or not) to be working to reduce or eliminate fossil fuel emissions that are driving the climate towards lethal runaway global warming. Clearly, both major political parties are still working hand in glove with the special interests to keep the fossil fuel industry growing through subsidies and permitting activities.

This is likely to continue as long as the special interests’ supporters are comfortable that they can work for their patrons and still get re-elected. This cozy connection between Parliamentarians and the fossil fuel industry will continue until the puppets are replaced by genuine representatives of voters who care about the future of our climate and the world their children and grandchildren will live (or die) in.

Stopping and reversing global warming is the only issue that really matters

There is a vast array of scientific and observational evidence showing that not only is the world growing ever warmer (thanks to the profligate burning of fossil carbon beginning with the Industrial Revolution), but that we have now warmed our planet enough that we are beginning to cross ‘tipping points’ for a number of positive feedback processes in the Earth System that will continue driving temperatures still higher even without further human intervention. Once positive feedback takes control of the thermostat, Earth’s temperatures will continue rising at an accelerating rate in a runaway global warming process until semi-stable ‘Hothouse Earth’ temperatures are reached. These temperatures will like be too hot and be reached too fast for large slowly reproducing organisms like humans to survive. The result will be our planet’s 6th global mass extinction event. At least two or three of the previous mass extinction events in our fossil record also seem to have been the result of runaway global warming.

Note: Straightforward laws of physics will produce this result unless humans can stop and reverse the process – and we are approaching a point of no return where no conceivable human intervention will be able to stop the feedback process before the fuel is exhausted or the system self-destructs.

Given that we are major users and producers of greenhouse gas emitting fossil fuels, we have to take the responsibility to do something about this….

We need to turn away from the the Apocalypse on the road to hothouse hell, and we won’t do this by continuing cosy relationships with fossil fuel producers and consumers.

In our present situation where most of our governments are still supporting and even funding fossil fuel production and use, the most effective actions we can take as individuals is to change our governments to prioritize action on climate change above all other things. Nothing else matters if we have no future….

States are probably even more important than the Federal Government where climate action is concerned

States enable and regulate mining and production of fossil fuels, and many of the important sources of emissions. Planning, industrial, rural, public safety and others are all primarily state concerns where political and administrative decisions may have considerable impact on regulating carbon emissions. Thus, if you are concerned to influence how your state acts in relation to the climate emergency, you need to elect representatives who will do this rather than bow down to wealthy patrons and vested interests who want to protect their short-term profits rather than humanity’s longer-term future.

The Victorian state election on 26 November is our next opportunity to begin focusing our state parliaments on the need to prioritize climate action. For Victorian voters, this may be the most important vote you ever make: Do you support major parties in their business as usual financial and regulatory support of the fossil fuel industry, or will you vote for a party or independent who is clearly focused on promoting and facilitating climate action?

Applying your decision to preferential voting on the ballot

If you believe that our present Labor government will govern in your interests rather than protecting and supporting their patrons in the fossil fuel and related industries, then go with the flow and don’t concern yourself with the likely consequences of going down their fossil fueled road towards runaway global warming. On the other hand, if you think it is better to work for a sustainable future where your children and their children can hope for a happy future, Vote Climate One can help you elect a government that will actively lead and support this effort.

Our Climate Lens Traffic Light Assessment process will help you to do this most effectively in both houses of Parliament. Also, our Climate Sentinel News provides access to factual evidence about the growing climate crisis to support your thinking, In the May Federal Election, our Traffic Light Voting System made it easy to use factual evidence about where each candidate in your electorate ranks in relation to their commitment to prioritize action on the climate emergency. We have modified this for the Victorian State Election in November.

Peter Trusler’s Self Portrait: Reduction

Victorian Election Reminder – Vote Climate One

The UN’s World Meteorological Organization warns us that we have done nothing to slow the global warming caused by our carbon emissions.

Message from the UN’s Secretary-General in the article

Geneva, 13 September 2022 (WMO) – Climate science is clear: we are heading in the wrong direction, according to a new multi-agency report coordinated by the World Meteorological Organization (WMO), which highlights the huge gap between aspirations and reality. Without much more ambitious action, the physical and socioeconomic impacts of climate change will be increasingly devastating, it warns.

The report, United in Science, shows that greenhouse gas concentrations continue to rise to record highs. Fossil fuel emission rates are now above pre-pandemic levels after a temporary drop due to lockdowns. The ambition of emissions reduction pledges for 2030 needs to be seven times higher to be in line with the 1.5 °C goal of the Paris Agreement….

If you are concerned about this visibly escalating climate emergency, but think there is nothing you can do about it, think again!

Major political parties primarily represent the vested interests who fund their candidates and election campaigns and work hard to protect their patrons. Many of these include rich fossil fuel and related industries (many based overseas) who would be harmed by climate action. As single individuals, we have been powerless to change the world against the political might of the ‘patrons’ and their government puppets…. But where your local communities and governments can coordinate together with a common goal to elect governments responsive to their citizens, we CAN change the world.

This has been demonstrated by the amazing exponential growth in the number of ‘community independent’ MPs working in our Federal Parliament since 2013: 1 house seat in 2013, 2 seats in 2016, 3 in 2019, and 10 + David Pocock in the Senate, following on from this year’s federal election that decimated the Liberal Party, giving a House majority to the Labor Party (a “Teal Tsunami).

However, even with Greens support, Labor is still one short of a majority in the Senate. This gives Pocock, a community independent, the deciding vote. As an immigrant rugby player from New Zealand, arguably he has become the most important senator in the Australian Parliament where climate action and integrity are concerned — selected, supported and endorsed by the Climate Change the local ACT community independently from the discipline of any political party.

Let David tell you in his own words:

ABC Australian Story, 13 Sept 2022
In the Australian Senate – 2 Aug 2022

As demonstrated, Labor’s climate climate change bill passed last week (8 Sept) with David Pocock’s ‘teal’ vote.


If you and your local community are unhappy with the way your sitting state or federal parliamentarians are representing your interests, the teal community independents can show you how to empower your communities to change that.

Work with your friends and neighbors to decide what you want from your representative(s) in government, select someone from your community to stand for election, support their campaign, and then vote them into office. My research as Editor of Climate Sentinel News, documents in detail how this works, and introduces the fabulous support network that the the successful teal community independents have developed to help empower other communities to become independent of the special interests supporting major party candidates:

Transforming Australia’s Parliament to act on climate (12 Sept 2022)

A rising tsunami of teal independents is transforming our democracy representing special interests to a participatory democracy of community representatives.

As noted in my many posts to Climate Sentinel News, it is becoming increasingly evident that humanity on our only planet faces near term extinction if we don’t manage to stop and reverse the global warming process we have started through our profligate burning of fossil fuels. Their emissions are preventing the Earth from radiating away excess solar energy. This imbalance between incoming and outgoing heat energy causes the world to grow warmer. Unfortunately the problem is global and can only be solved on a global scale through the cooperation of governments – which makes it unavoidably political.

The difficulty of solution is only compounded by the fact that the unimaginably rich global fossil fuel industry has been fighting for decades to disrupt and stop effective actions against global warming/climate change to protect their sources of income from the burning of fossil fuels causing the emissions. Even the supposedly most ‘democratic’ governments have been corrupted so they represent the patrons and special interests (mostly fossil fuel industry related) who support and fund major political parties. This influence is so strong that I have been deeply pessimistic that our governments would ever be able to work effectively to combat climate change and stop our progress along the runaway warming road to extinction.

However, the results of Australia’s May 21 Federal Election provide evidence that Australia has begun to transform its government into one truly representing the substantial majority of voters who want action on climate change to be prioritized above any other issue. Finally there is scope for some genuine optimism that our government(s) will actually work seriously to resolve the climate issues….

Our changes to Earth’s atmosphere are driving us down the slippery road to mass extinction in ‘Hothouse Earth

The featured image heading this post and the video below show the most recent and best documented evidence that nothing humans have done to date has significantly slowed the accelerating rise in global temperatures driving by rising greenhouse gas concentrations from or directly triggered by human activities. If nothing is actively done on a global scale to stop and reverse these increases, it is inevitable that within a few more decades that our planet will have become uninhabitable to humans and the other living resources we need for our survival.

The graphs above and the video here are pretty clear. Objective measures of our planetary atmosphere show that we have done nothing yet in the world that is changing this prediction.

The video from the US National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Laboratory shows the historical fluctuations in CO2 concentrations in the atmosphere we breathe over the last 800,000 years. It begins in 1979 when detailed daily tracking of atmospheric greenhouse gas concentrations began in a serious way across the globe using both physical sampling and measurements combined with satellite remote sensing. The inset map shows sampling locations, the fluctuating line plots CO2 concentrations by distance of the location south or north of the Equator and the graph shows annual fluctuations and the year-by-year rise in the average concentration for the year up through 2021.

When the present is reached, the x-axis of the graph is extended backwards in time from 1979 using a variety of measurement tools, mostly the CO2 concentration in bubbles of atmospheric gas trapped in bubbles of gas frozen into glacial ice from Antarctica. (The modern and ice-core measurements overlapped for long enough to demonstrate that the different sampling technologies were giving the same results.)

Until now I have been quite pessimistic that adequate action would ever be taken to reverse the trends shown on these graphs as our governments will continue greasing the downhill slide into the death and chaos of global mass extinction.

Community independents and Greens know how to change that, and have shown that they actually have the knowledge and ability to cancel remove the power of major political parties to block effective action.


Action is required! Simply voting for a Party may not ensure our survival (or may even speed our demise). Learn how to Vote Climate One!

I am now decidedly optimistic that humans have the knowledge and power to stop the ultimately lethal processes we have accidentally triggered in our profligate burning of Earth’s carbon resources. All it takes is a willingness for communities to be come fully involved in their own interests in avoiding the extinction of their families and heritage.

If you don’t think a major party you have voted for in the past truly represents your interests (rather than those of their immensely wealthy patrons — who may not even be Australian), Vote Climate One will show you how to maximize the chances that your vote will help to elect someone who will actually represent your community interests. See our Vote Climate One page on Voting Guides. At the moment this reflects the past Federal Election, but it will give the idea of the kind of analysis and information we will provide for the Victorian state election in November. The Victorian State Election guide will not be finalized before Sunday Nov.13th when the Victorian Electoral Commission releases the final list of candidates for each electorate. Prepolling starts on Monday Nov. 14th. We should have draft versions of the Victorian guides on-line around the beginning of November.

If you want to maximize the chances that your vote will actually count towards electing a government that will prioritize acting on climate first, we’ll do the work to make it easy for you to vote effectively.


greta-act-as-if-the-house-was-on-fire
Listen to Greta’s speech live at the World Economic forum in Davos 2019. Except for her reliance on the IPCC’s overoptimistic emissions budget, everything she says is spot on that even she, as a child, can understand the alternatives and what has to happen.

In other words, before you cast your ballot: Wake up! Smell the smoke! See the grimly frightful reality; and fight the fire that is burning up our only planet so we can give our offspring a hopeful future. This is the only issue that matters. Even the IPCC’s hyperconservative Sixth Assessment Report that looks at climate change’s global and regional impacts on ecosystems, biodiversity, and human communities makes it clear we are headed for an existential climate catastrophe if we don’t stop the warming process. To do this our governments must accept the reality, and work effectively to plan and coordinate the necessary mobilization and action. YOUR VOTE IN THE VICTORIAN ELECTION CAN HELP ENSURE THAT THIS HAPPENS: Vote Climate One in November!

August 2022 Greenhouse Gas Report

No evidence here that humans have done anything yet to stop and reverse GHG emissions to get us off the road to Hothouse Earth and global mass extinction.

As the ocean ice around Antarctic approaches its maximum spread for the year, on 19 August 2022 Antarctic sea-ice extent is the second lowest ever as recorded in the satellite era as recorded by the US National Snow & Ice Data Center. As sunlight again begins to shine on the antarctic polar region more of the ocean surface is exposed to solar heating that will warm the waters surrounding the ice cap to speed glacial melting and slow the formation of more sea-ice next winter.

July’s trends in global warming continue in August. Heatwaves, fires, and droughts in the Northern Hemisphere continue, e.g:

In the run-up to Australia’s May 22 Federal Election many articles on our Climate Sentinel News documented the reality, mechanisms and dangers humans face if global warming is allowed to continue. If global warming runs away due to already documented feedback mechanisms heating will continue at an accelerating rate that will soon rise beyond the capacity anything humans can do to stop it.

Critical time is wasting. It is time for all of our politicians, new and old to lead our country in massive mobilization to stop carbon emissions and start implementing carbon capture and sequestration processes able to extract excess amounts from the atmosphere. Biological processes are likely to scale up a lot more successfully than engineering solutions. Geoengineering to increase Earth’s reflectivity (i.e., albedo reduction) may also help. We know how to stop emissions, but sequestration and albedo reduction will require significant research that needs to start now.

TIME IS OF THE ESSENCE, AND THE URGENCY GROWS WITH EVERY DAY OF DELAY!

July 2022 Climate – still on road to extinction

Australia has a new government. Every month we fail to stop global warming is a month closer to global mass extinction. Still no visible progress towards solution.

The graphic above downloaded today shows the current state of sea-ice surrounding the Antarctic continent. Despite what seems to be a cold winter in Victoria, its coverage indicated by the teal blue line in the chart is 530 km2 smaller than it has ever been before for this time of the year. There are many more indicators that the climate is still deteriorating towards making Earth uninhabitable for its present life forms (including humans!) at an accelerating rate.

The following news items underline the dangers this represents for humans.

Model-analyzed temperatures at 12Z Tuesday, July 19, 2022 (noon GMT) were transcending average values for the time of day and season by 12 to 24 degrees Celsius—or 22 to 33 degrees Fahrenheit—over large parts of northwestern Europe. (Image credit: tropicaltidbits.com) [from the article]

Horrific heat descends upon Western Europe: 104°F in London

Dozens of all-time record highs melted on Monday and Tuesday under a searing, deadly European heat wave that has caused at least 1,169 heat-related deaths in Spain and Portugal. The heat wave has also brought the hottest day on record for many locations in France and the hottest temperatures — by far — ever observed in the United Kingdom.

The record-smashing heat in Europe’s normally mild, maritime northwest corner was eerily comparable to the astounding heat wave in the U.S. Pacific Northwest and far southwest Canada in June 2021. The latter was found to have been “virtually impossible” without human-produced climate change.

By 9 a.m. GMT on Tuesday, July 19, London’s Heathrow Airport had already surged past 90°F, and at 12:50 p.m., the airport’s official observing site for London recorded what, if confirmed, would be the hottest temperature in London history: 40.2 degrees Celsius, or 104.4 degrees Fahrenheit.

‘Soon it will be unrecognisable’: total climate meltdown cannot be stopped, says expert

Blistering heatwaves are just the start. We must accept how bad things are before we can head off global catastrophe, according to a leading UK scientistRobin McKie.

The publication of Bill McGuire’s latest book, Hothouse Earth, could not be more timely. Appearing in the shops this week, it will be perused by sweltering customers who have just endured record high temperatures across the UK and now face the prospect of weeks of drought to add to their discomfort.

And this is just the beginning, insists McGuire, who is emeritus professor of geophysical and climate hazards at University College London. As he makes clear in his uncompromising depiction of the coming climatic catastrophe, we have – for far too long – ignored explicit warnings that rising carbon emissions are dangerously heating the Earth. Now we are going to pay the price for our complacence in the form of storms, floods, droughts and heatwaves that will easily surpass current extremes.

In the run-up to the May 21st Federal Election, I posted many more articles documenting the increasing risk of mass extinction that humans face if we do not stop and reverse the runaway acceleration that is flipping our global climate to the Hothouse Earth state.

In the Election Australians replaced the Liberal/National COALition with a more climate friendly Labor government supported by an extensive cross-bench of climate-friendly independents (‘teals‘) and Greens.

The Government has very little time (if any – see the article above) to act to stop carbon emissions and to do what we can to remove some of the past excesses from the atmosphere.

TIME IS OF THE ESSENCE!

Time series graphs showing the variation in the three most important greenhouse gases as observed and recorded by the US National Oceanic and Atmospheric Administration, Global Monitoring Laboratory at Mauna Loa Observatory, Hawaii.

The carbon dioxide data on Mauna Loa shown in the top row constitute the longest record of direct measurements of CO2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976]. The first graph shows atmospheric CO2 concentrations over the last five complete years of the Mauna Loa CO2 record plus the current year. The second graph shows annual mean CO2 growth rates for Mauna Loa. In the graph, decadal averages of the growth rate are also plotted, as horizontal lines for 1960 through 1969, 1970 through 1979, and so on.

The middle row charts the growth of atmospheric methane: the first graph shows the full NOAA time-series starting in 1983, The red circles are globally averaged monthly mean values centered on the middle of each month. The black line and squares show the long-term trend (in principle, similar to a 12-month running mean) where the average seasonal cycle has been removed.The second graph summarizes annual increases in atmospheric CH4 based on globally averaged marine surface data.

The bottom row charts the growth of atmospheric N2O (Nitrous oxide) beginning in 2001, when NOAA began to have confidence in the data. Values for the last year are preliminary pending recalibrations of standard gases and other quality control steps. The second graph plots the annual increase in atmospheric N2O in a given year, i.e., the increase in its abundance (mole fraction) from January 1 in that year to January 1 of the next year, after the seasonal cycle has been removed (as shown by the black lines in the first figure). It represents the sum of all N2O added to, and removed from, the atmosphere during the year by human activities and natural processes.

As yet, there is NO evidence that any of these values are beginning to stop increasing, let alone decrease, as the result of any human actions.

Thawing permafrost: Big climate system danger

Permafrost holds 2x more carbon than Earth’s atmosphere and 3x more than all forests. Thawing will hugely impact global climate warming

Science Session: Thawing Arctic Permafrost–Regional and Global Impacts

by US National Academy of Sciences, 12/05/2020

Science Session: Thawing Arctic Permafrost–Regional and Global Impacts

Temperatures across the Arctic are increasing two to four times faster than the global average. The dramatic consequences that are already apparent include reduction of sea-ice cover, accelerating loss of land ice from glaciers and the Greenland Ice Sheet, proliferating wildfires, and—the topic of this panel—ongoing heating and thawing of the permafrost that underlies most of the land area of the Arctic and sub-Arctic regions across the globe. Permafrost thaw is a direct threat to buildings, roads, and pipelines, and it can greatly accelerate erosion along rivers and coastlines with severe consequences for communities located there. But an impact with much wider consequences is the release of carbon dioxide and methane by the decomposition of previously frozen organic matter, affecting the rate of growth of global warming and all of its impacts everywhere. (There is estimated to be something like 2.5 times as much carbon in the as in the entire global atmosphere; the key question is how fast it will come out.) The panelists, leading Arctic experts all, explain the complex science of thawing permafrost and elucidate the implications both regionally and globally.

Editors note: I have often mentioned the potential risk of rapid permafrost thawing serving as a source of powerful positive feedback on global warming from the abrupt emissions of greenhouse gases. The emissions include methane, which has a global warming potential more than 80 x that of CO. The video runs for almost 1½ hours. However, if you want to understand how science works in what are relatively conservative approaches and whether the risks that concern us in the Vote Climate One group are real, the whole video should be well worth watching.

In this pay particular attention to what is left out of the predictive models for future growth of emissions. The actual reality is likely to be even worse.

Finally, a lot of the discussion is based on the idea still common in 2020, that there is some kind of ’emissions budget’ that allows time to stop anthropogenic emissions. With more data, e.g., from the still conservative IPCC Sixth Assessment Report there is much less mention that there is no ‘safe’ emissions budget. Action to slow and reverse global warming is urgent! To be effective this will need global mobilization with cooperation at government levels as well as involving people. Here, our government in Australia has been quite hostile to any kind of action on global warming because of their apparently rusted-on allegiance to the fossil fuel industry and super-wealthy special interests associated with it.

In Scotty’s own words in one of his pet mediums – something to think about:

Prime Minister Scott Morrison says he supports Australia’s fossil fuel industry – and particularly coal, which he… says will be around for “decades to come”. “When it comes to the coal industry, it’s worth $35 billion to us every year in exports, and that’s money Australia needs to grow our economy,” Mr Morrison said. “What you need in today’s energy economy is you need to continue to run your coal-fired power stations for as long as you possibly can and that is our policy … we want them to run as long as they possibly can.” Coal-fired power stations will continue to run to back up renewable power sources, although Mr Morrison said gas would play a larger role in the energy mix in years to come. Mr Morrison added that building a new coal-fired power station would be difficult because of the state government planning powers, which would “probably never allow them to do it”. For the video see: The Australian, 14/03/2022, Commentary/coal-will-be-around-for-decades-to-come-scott-morrison/video. See also ‘We will keep mining’, says Australian prime minister Scott Morrison about the future of coal.

What can/must we do about this dreadful government and even worse situation?

We need to turn away from the the road to hothouse hell, and we won’t do this by continuing with the kind of business as usual Scotty from Maketing and his fossil fuel puppets are spruiking!

It seems to take the clear thinking of Greta Thunberg, a 16 year-old autistic girl who concluded school was pointless as long as humans continued their blind ‘business as usual’ rush towards extinction.

greta-act-as-if-the-house-was-on-fire
Listen to Greta’s speech live at the World Economic forum in Davos 2019. Except for her reliance on the IPCC’s overoptimistic emissions budget, everything she says is spot on that even she, as a child, can understand the alternatives and what has to happen.

In other words, wake up! smell the smoke! see the grimly frightful reality, and fight the fire that is burning up our only planet so we can give our offspring a hopeful future. This is the only issue that matters. Even the IPCC’s hyperconservative Sixth Assessment WG2 Report that looks at climate change’s global and regional impacts on ecosystems, biodiversity, and human communities makes it clear we are headed for climate catastrophe if we don’t stop the warming process.

Scott Morrison and his troop of wooden-headed puppets are doing essentially nothing to organize effective action against the warming. In fact they have expended considerable effort to deny the science, punish the institutions doing the science, misrepresent the facts, and try to divert interest to anything else but action on climate change. Beyond this they are continuing to support and subsidize continued expansion of the fossil fuel industry. Basically, all they doing is throwing coal on the fire and rearranging the furniture in the burning house to be incinerated along with anything and everyone we may care about.

In Greta’s words, “even a small child can understand [this]”. People hope for their children’s futures. She doesn’t want your hopium. She wants you to rationally panic enough to wake up, pay attention to reality, and fight the fire…. so our offspring can have some hope for their future. Vote Climate One’s Traffic Light Voting System will help you use your preferential votes wisely on behalf of our offsprings’ future.

Our young ones are walking into an unknown future. Give them hope and not the Ukraine.

First-of-its-kind detection of reduced human carbon dioxide emissions

For the first time, researchers have spotted short-term, regional fluctuations in atmospheric carbon dioxide (CO2) around the globe due to emissions from human activities.

Using a combination of NASA satellites and atmospheric modeling, the scientists performed a first-of-its-kind detection of human CO2 emissions changes. The new study uses data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) to measure drops in CO2 emissions during the COVID-19 pandemic from space. With daily and monthly data products now available to the public, this opens new possibilities for tracking the collective effects of human activities on CO2 concentrations in near real-time.

Mass extinctions and climate change: why the speed of rising greenhouse gases matters

[G]reenhouse gases are rising faster than at any time since the demise of dinosaurs, and possibly even earlier. According to research published in Nature Geoscience this week, carbon dioxide (CO₂) is being added to the atmosphere at least ten times faster than during a major warming event about 50 million years ago.

We have emitted almost 600 billion tonnes of carbon since the beginning of the Industrial Revolution, and atmospheric CO₂ concentrations are now increasing at a rate of 3 parts per million (ppm) per year.

With increasing CO₂ levels, temperatures and ocean acidification also rise, and it is an open question how ecosystems are going to cope under such rapid change.

Wildfires devastate the land they burn, and they are also warming the planet: The 2021 wildfire season broke records globally, leaving land charred from California to Siberia. The risk of fire is growing, and a recent report warned that wildfires are on track to increase 50% by 2050. These fires destroy homes, plant life, and animals as they burn, but the risk doesn’t stop there. Researchers detail how the brown carbon released by burning biomass in the northern hemisphere is accelerating warming in the Arctic and warn that this could lead to even more wildfires in the future.
