Earth’s annual healthcheck — and our future

Climate News Links on March 5, 2023

A compendium of graphs plots key indicators of our changing climate. Unless trends are reversed today’s lethal extremes will be ‘lethal ‘new normals’.

Climate scientist Zach Labe shows us in a collection of simple graphs from his WordPress page how many of Planet Earth’s vital signs have been changing over recent decades. He plots the best available data, and lets the plots tell the story without adding his redundant commentary.

However, If you want, you can still follow links that explains how the data was collected and analyzed. Click on Climate Visualizations at the top of the screen to open a pull-down menu, and then on FAQ and my methods at the bottom of that menu.

Plotting the reality

Four critical variables (the three critical greenhouse gases and global average temperature) show us how our changing climate is progressing.

The collection of graphs shows completely unambiguously that ever more heat energy is being loaded into our planetary climate system to make it hotter and more humid — where heat and humidity are the drivers for all kinds of extreme weather events.

If you look at the most recent years of Rising Temperature (beginning with 2020) you might think temperatures have stopped rising. However, this is almost certainly dangerously wrong. We have just finished an unusual three successive periods of La Niña conditions that result in below average global temperatures. GIven the generally increasing rate of temperature rise, the next El Niño periods are likely to be substantially hotter than the last ones (2014-2019) when Australia suffered the record-breaking bushfires of our Black Summer that even burned temperate rainforests that survived previous fires for many hundreds of years.

What do the graphs tell us?

In the past VoteClimateOne’s Climate Sentinel News has posted many articles attesting to the increasing frequency, extent and ferocity of extreme weather and the increasing chaos and costs these cause.

As the energy in the climate system continues to rise, catastrophes will increasingly overlap such that more damage and chaos will be caused by following events before recovery from earlier ones is complete. We are already seeing examples of this in NSW’s Northern Rivers and southwestern areas. At some point (in the not distant future — if global warming is not reversed) the still growing social and physical costs will lead to social and physical collapse of society.

Can you do something to change the picture?

At this point both major political parties in the NSW government are still defending and even subsidizing the fossil fuel industry’s (coal and gas) continuing increasing emissions of greenhouse gases.

It is time for you to help elect a government able to act effectively against the climate emergency by ensuring neither party has a majority to do things without people’s support. Hard-right members in either party who will do deals with anyone to stay in power to enforce their religiofascist dogmas tend to ignore even stark objective realities such as the climate crisis shown by Earth’s vital sighs. Such people need to be replaced by electing teals, other community-oriented independents and Greens who accept the reality of the climate emergency and are willing to prioritize acting on it.

My Climate Sentinel News article, Is Premier Perrettet a far-right puppet, or the puppet master?, documents and explains how the kind of ultra dogmatic hard-right politicians got into power that most need to be replaced by parliamentarians who will represent and work for the voters’ benefits. As the now deceased Lyenko Urbanchich, ex MLC David Clarke, federal Senator Alex Hawke, the Tudehope family and the Perrottet family have shown on the far right of the NSW Liberal Party, if your faction can fill key positions in party and factional organizations with collaborators who can organize cadres of ‘storm troops’, it is easy to put whoever the faction ‘leader(s)’ may want into Parliament. The party’s ‘safest’ seats are taken over by using the cadres to subvert preselections by branch stacking and simple thuggery or by bypassing preselection entirely with direct appointments (as has been demonstrated many times over the 40 years of history covered in my article).

Here I focused on the Liberal hard-right. But it should be recognized that Labor also has had and probably still has a very similar hard-right. This was made most evident in the impact Bob Santamaria had on the Labor Party in the 1950’s that led to it a near-lethal split to form the Democratic Labor Party. I have not had the time to adequately research the NSW Labor Party, but its leader, Chris Minns shares many characteristics with Dominic Perrottet, and has even backed and defended him over the treatment of climate protester Violet Coco. Like the Liberals, Labor also safe seats giving factions many opportunities to subvert real democracy. To me this is more than enough reason for VoteClimateOne to advise voters in such seats not to vote for factional puppets in hopes of making the seat marginal. Even if you don’t get rid of the puppet this time, you may be given a real opportunity in the next election to preselect someone actually representing you (rather than someone dogma) in the next election.

How to vote?

We won’t suggest who you should vote for. However we try to show you in our NSW voting guides where we think each candidate in your electorate stands relative to action on the climate emergency and whether we think there are reasons a particular candidate might be considered to be a puppet or less trustworthy on issues than others in the electorate. These recommendations won’t be complete or final until we have had a chance to work our way through those on the ballots provided by the Electoral Commission.

Health Minister Minster Mark Butler says ongoing trauma can manifest in increased rates of anxiety, post-traumatic stress and domestic and family violence: “Mental health is one of the government’s highest priorities and I recognise that these flooding events have been hugely traumatic for many people,” he said…. For some of these communities, this has been their fourth flood in 18 months.”

Proof that humans caused rapid global warming

William P. Hall on October 22, 2022

US National Oceanic and Atmospheric Agency summarizes evidence that humans are responsible for huge CO₂ emissions driving rapid global warming.

Rock solid evidence leaves no other explanations able to explain the observations. Humans caused the problem. Humans should be able to do something about it!

By Rebecca Lindsey, October 12, 2022 on Climate Q&A

How do we know the build-up of carbon dioxide in the atmosphere is caused by humans?

The most basic reason is that fossil fuels—the equivalent of millions of years of plant growth—are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts as high and as quickly as they have risen. The increase between the year 1800 and today is 70% larger than the increase that occurred when Earth climbed out of the last ice age between 17,500 and 11,500 years ago, and it occurred 100-200 times faster.

In addition, fossil fuels are the only source of carbon consistent with the isotopic fingerprint of the carbon present in today’s atmosphere. That analysis indicates it must be coming from terrestrial plant matter, and it must be very, very old. These and other lines of evidence leave no doubt that fossil fuels are the primary source of the carbon dioxide building up in Earth’s atmosphere.

Carbon dioxide over 800,000 years

The featured image is from the article above. It shows the variation in atmospheric CO2 concentrations over the last 800,000 years of time. The caption explains:

Global atmospheric carbon dioxide (CO2) in parts per million (ppm) for the past 800,000 years based on ice-core data (purple line) compared to 2021 concentration (dark purple dot). The peaks and valleys in the line track ice ages (low CO2) and warmer interglacials (higher CO2). Throughout that time, CO2 was never higher than 300 ppm (light purple dot, between 300,000 and 400,000 years ago). The increase over the last 60 years is 100 times faster than previous natural increases. [my emphasis] In fact, on the geologic time scale, the increase from the end of the last ice age to the present looks virtually instantaneous. Graph by NOAA Climate.gov based on data from Lüthi, et al., 2008, via NOAA NCEI Paleoclimatology Program.

Also from Climate Q&A, see two related articles: What evidence exists that Earth is warming and that humans are the main cause?; and Which emits more carbon dioxide: volcanoes or human activities?

Why is this important?

Many articles on Climate Sentinel News provide evidence that global temperatures are already reaching very dangerous thresholds. If we do not stop human generated/activated carbon emissions, positive feedbacks driven by the increasing temperatures will increase natural greenhouse gas (GHG) emissions fast enough to keep temperatures rising even if we completely stop human GHG emissions (e.g., the warming process will run away – see Climate Crisis! The only issue that matters, Tripping down the road to Earth’s Hothouse Hell and Global Mass Extinction, and Apocalypse will come if global warming is not stopped.

If we do not stop global warming, there is probably enough carbon readily available for emissions in soil, permafrost, and biomass to drive temperatures high enough to exterminate most complex life on Earth (the 6th global mass extinction).

What can we do about it?

Because the climate crisis is a global threat for the whole of humanity, there is very little a single human can do in isolation to stop and turn around the warming process. Effective action has to be guided and managed at international, national and state levels before individual actions become effective. Consequently, the single most effective things individual people can do is to elect representatives to government who will respond actively and seriously to ensure that our governments are taking appropriate and effective actions.

Where governments are concerned, state governments probably have the most power to directly manage and control responses to climate change through their controls of environmental regulations, planning and permitting. In Australia, Victorians will have an opportunity around a month from now (on on 26 November 2022) to elect members for the next Parliament of Victoria. All 88 seats in the Legislative Assembly (lower house) and all 40 seats in the Legislative Council (upper house) will be up for election. The most important thing you can do to respond to the climate crisis is to elect upper and lower house representatives committed to effective action on the climate crisis.

Voting in Australia’s preferential voting system requires careful consideration if you care about the result.

Applying your decision to preferential voting on the ballot

If you believe that our present Victorian Labor government will govern in your interests rather than their corporate and union 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 long and happy lives, Vote Climate One can help you elect a government that will actively lead and support this work.

In general, we think a minority government led by Labor, where the balance of power is held by Greens and pro-climate community independents will give us the parliamentary representation that will give us the best outcome.

The trouble with party led majority governments is that the large parties are all disciplined to follow a party line. All too often super wealthy special interest patrons including non-citizen overseas entities strongly influence parties via large ‘donations’ and campaign support. Far better to give the last word on parliamentary decisions to MPs owing allegiance to the citizens who elected them than to people constrained to follow party disciplines..

Vote Climate One was formed for the specific purpose of studying and ranking all political parties and independent candidates on their policies and promises relating to climate and related environmental issues. What are they committed to do, and can you trust them to keep to their commitments. This is expressed in our Climate Lens Traffic Light Assessment process. (The results and their presentation are still being processed for the Victorian Election as this is being written).

Questionnaire used along with other kinds of evidence in our evaluation of candidates.

Our Climate Sentinel News provides access to factual evidence about the growing climate crisis to support your thinking; and our Traffic Light Voting System gives you easy to use factual evidence developed through our assessment process about where each candidate in your electorate ranks in relation to their commitment to prioritize action on the climate emergency. This should make it easier to decide your voting preferences before confronting a long ballot paper in the voting booth. We do the work so you can easily cope with Victoria’s complex party-based preferencing to plan your voting before you enter the booth.

We need to turn away from the the Apocalypse on the road to hothouse hell, and we won’t do this by continuing with business as usual!

It seems to have taken the clear thinking of Greta Thunberg, a 16 year-old 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 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.

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. As individuals, our most effective fire axe is to elect the right people to government who can lead and coordinate the fire fight.

Let’s hope that we can stop global warming soon enough to leave them with a future where they can survive and flourish

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.

New liquid-based CO₂ capture tech for industrial emissions

William P. Hall on February 13, 2022

Shows capacities for high CO2 capture under power plant operating conditions, minimizing energy-intensive temperature swings of other techs

by Mohen S. Yeganeh, et al. 11/02/2022 in Science Advances
Solid with infused reactive liquid (SWIRL): A novel liquid-based separation approach for effective CO2 capture: Economical CO2 capture demands low-energy separation strategies. We use a liquid-infused surface (LIS) approach to immobilize reactive liquids, such as amines, on a textured and thermally conductive solid substrate with high surface-area to volume ratio (A/V) continuum geometry…. [The technology] shows stable, high capture capacities at power plant CO2 concentrations near flue gas temperatures, preventing energy-intensive temperature swings needed for other approaches.

VC1 Editor’s comment: The science behind this technology appears to be valid, but implementing it will be too costly and engineering intensive for applications other than mitigating already concentrated carbon emissions from power plant flue gases and other large-scale industrial emitters. However, in this application the technology described here would seem to have significant advantages over other proposed technologies.
