We’re racing down “highway to climate hell” (UN Chief)

William P. Hall on November 8, 2022

UN Chief, Antonio Guterres warns world leaders at COP 27 summit that nations must cooperate or face “collective suicide” from climate change.

Guterres pulled no punches in his opening address to heads of state and other national leaders attending the climate summit: “Humanity has a choice: cooperate or perish,” “It is either a Climate Solidarity Pact or a Collective Suicide Pact,” he added…. “We are on a highway to climate hell with our foot still on the accelerator,”

World risks ‘collective suicide’, UN chief warns climate summit

The UN’s chief warned Monday that nations must cooperate or face “collective suicide” in the fight against climate change, at a summit where developing countries reeling from global warming demanded more action from rich polluters.
Nearly 100 heads of state and government are meeting for two days in Egypt’s Red Sea resort of Sharm el-Sheikh, facing calls to deepen emissions cuts and financially back developing countries already devastated by the effects of rising temperatures.
“Humanity has a choice: cooperate or perish,” Guterres told the UN COP27 summit.

In his own words:

These are no empty words — Guterres is reporting on what the best science available to us we must do to avoid the highway to climate hell

Supporting Guterres’s stark warnings is a vast array of physical evidence (i.e., satellite and direct measurements) on climate change and theoretical modeling. This shows beyond any reasonable doubt that humanity is indeed accelerating down the “highway to climate hell”. Some of this evidence was reviewed in David Spratt’s series of articles in Climate Code Red, beginning in January. Those articles and my contextual comments covering them discussed some of the tipping points we may be passing on our progress towards the point of no return where positive feedbacks in Earth’s climate system.

The featured image in the present post and in my seven posts on the Spratt series is from a 2018 article by Steffen et al. in the prestigious science journal, Proceedings of the National Academy of Sciences (PNAS), “Trajectories of the Earth System in the Anthropocene“. The image is a highway map showing the alternative roads: to “climate hell” and suicide, or to planetary stewardship and survival on a “Stablized Earth”.

The “Trajectories” paper identifies various tipping points in the climate system where intrinsic temperature-related positive feedbacks would continue driving global temperatures higher when global warming reached those points. If the warming is not stopped, a “planetary threshold” (i.e., ‘point of no return’) will soon be reached where the intrinsic feedbacks become so strong that nothing humans could plausibly do would stop global temperatures being pushed high enough to produce a “Hothouse Earth” and global mass extinction (including humans). Fig. 1 (below) and the featured image provide a map illustrating how humans might be able to divert the evolution of our climate away from the heat driven highway over the planetary threshold (point of no return) where societal collapse and extinction becomes more-or-less inevitable.

**Fig. 1.** A schematic illustration of possible future pathways of the climate against the background of the typical glacial–interglacial cycles (*Lower Left*). The interglacial state of the Earth System is at the top of the glacial–interglacial cycle, while the glacial state is at the bottom. Sea level follows temperature change relatively slowly through thermal expansion and the melting of glaciers and ice caps. The horizontal line in the middle of the figure represents the preindustrial temperature level, and the current position of the Earth System is shown by the small sphere on the red line close to the divergence between the Stabilized Earth and Hothouse Earth pathways. The proposed planetary threshold at ∼2 °C above the preindustrial level is also shown.

As Guterres said, if we act soon enough and with enough vigor to stop carbon emissions and do whatever else is necessary, we may be able to find the left turn off the highway to climate hell. By being good stewards of our limited resources we may be able to find our way along the less probable road to a “Stabilized Earth” where Earth’s climate can return to the kinds of tolerable conditions humanity evolved and flourished in. After 45 years of hiding from the problem and allowing it to become progressively worse, saving our species from the highway to hell will take global mobilization of a monumental effort.

Otherwise, If we continue with business as usual supporting our fossil fuel puppet masters, the highway to hell will inevitably take us over the cliff to our doom. We have a choice. “Cooperate or perish”.

What must we do?

In Australia our present governments are still at least partially in league with the fossil fuel industry. Science tells us that we must stop all carbon emissions as fast as we possibly can. Yet all of our governments continue various subsidies for the industry, allowing them to continue developing new projects, trying to extend the life of coal-fired generators and selling cheaply produced natural gas (even in the states where it is produced) for some of the world’s highest prices to make astronomical profits for mostly foreign owners. Most of these schemes were perpetrated under COALition governments, but today’s national and Victorian Labor governments continue to support them.

We need to work to ensure no major party/coalition can achieve government without Greens and/or climate friendly community independents in the balance of power. This was achieved by one vote in the Senate (the ACT’s David Pocock). In Victoria, Labor’s Dan Andrews enjoys a presently dictatorial lead over a Liberal/National Party coalition. If we are to achieve the kinds of sweeping climate goals we need, Community oriented climate activists are going to need to be elected in both COALition and Labor Party held seats. Vote Climate One’s Climate Lens is designed to help you select climate friendly and trustworthy candidates, and to use Victoria’s preferential voting scheme most effectively to give your selected candidates the best opportunities to win the seat.

Using our Climate Lens in Victoria

In Australia, states probably have more capacity for effective climate action than the national government. Victoria’s upcoming state election should be an election focused on the only issue that really matters, climate.

The Victorian ballot is far too complicated and is deliberately designed to keep all the power in the hands of whichever major party is in the majority.

Vote Climate One emerged to help people cope easily with complex ballots to focus on electing the kinds of candidates who we think can be trusted to legislate and lead effective climate action. We do this in two major ways: using our Climate Lens help you assess who is pro climate vs those who are not; and using Climate Sentinel News’s searchlight to highlight and explain the facts that show why climate change is so dangerous and climate action is so important.

The fork in the road in Fig. 1 is shown here as the two divergent pathways of the Earth System in the future (broken arrows). Currently, the Earth System is on a Hothouse Earth pathway driven by human emissions of greenhouse gases and biosphere degradation toward a planetary threshold at ∼2 °C (horizontal broken line at 2 °C in Fig. 1), beyond which the system follows an essentially irreversible pathway driven by intrinsic biogeophysical feedbacks. The other pathway leads to Stabilized Earth, a pathway of Earth System stewardship guided by human-created feedbacks to a quasistable, human-maintained basin of attraction. “Stability” (vertical axis) is defined here as the inverse of the potential energy of the system. Systems in a highly stable state (deep valley) have low potential energy, and considerable energy is required to move them out of this stable state. Systems in an unstable state (top of a hill) have high potential energy, and they require only a little additional energy to push them off the hill and down toward a valley of lower potential energy.

Have we reached the point of no return on the road to runaway warming ending in near-term global mass extinction (including humans)?

William P. Hall on February 3, 2022

Part 7 – concluding David Spratt’s guidebook to events along the road to Hothouse Hell: Have we triggered so many tipping points already that we are already at or past the point of no return?

Clearly, we wont know if we have passed the point of no return until it is too late to do anything about it. Spratt’s concluding comments to his guidebook need no embellishment from me. He lists 7 points. Basically I agree with all of him, except that I would state several of them even more strongly than he does:

Have tipping points already been passed for critical climate systems? (7) Summing up: Faster than forecast, cascades loom

Reflecting on the evidence presented in this tipping point series, a number of conclusions may be drawn:
1. At just 1.2°C of warming, tipping points have been passed for several large Earth systems. At just 1.2°C of global average warming, tipping points have been passed for several large Earth systems. These include Arctic sea ice, the Greenland Ice Sheet, The Amundsen Sea glaciers in West Antarctica, the eastern Amazonian rainforest, and the world’s coral systems. The world will warm to 1.5°C by around 2030, with additional warming well beyond 1.5°C in the system after that. Yet even at the current level of warming, these systems will continue to move to qualitatively different states. In most cases, strong positive feedbacks are driving abrupt change. At higher levels of warming, the rate of change will quicken. The meme that “we have eight years to avoid 1.5°C and tipping points” should be deleted from the climate advocacy vocabulary. It is simply wrong.

2. System-level change is happening faster than forecast. In each case surveyed above, abrupt change is happening earlier and/or faster than projected only two decades ago. The 2007 Arctic sea-ice collapse was “100 years ahead of schedule”; in 2014 the tipping point for Amundsen Basin glaciers was one that “none of us thought would pass so quickly”. It was said that the guardrail for coral reefs was warming under 2°C, then 1.5°C; it is now clear that it is under 0.5°C. In 1995, the IPCC projected “little change in the extent of the Greenland and Antarctic ice sheets… over the next 50-100 years”. The 2001 IPCC report suggested that the Greenland and the West Antarctic ice sheets would not lose significant mass by 2100. Both have now passed their tipping points. The effect of the permafrost carbon feedback has not been included in the IPCC scenarios, including the 2014 report. And on it goes.

It’s an Emergency!

In this now completed series of posts, Spratt has done an excellent job of summarizing the scientific observations that sound the klaxon fire alarm warning us that our planet is on fire. If we don’t wake up, smell the smoke, and mobilize global action to fight the fire, it will consume us humans along with most other complex life who share the still green(ish) planet with us.

The puppets show and tell — Captain Humbug (a.k.a. Scotty from Marketing) behind his then leader’s back, showing Barney Bulldust and the parliamentary puppet troop what he is promoting. ““Don’t be afraid, don’t be scared, it won’t hurt you. It’s coal.” With these words Australia’s Treasurer Scott Morrison taunted the Opposition, attempting to ridicule its commitment to renewable energy.” – The Conversation (15-02-2017). Note: The fourth man — the holy ghost – later stabbed in the back by Scotty, was also previously a marketeer of the merchant banking type, by and for the special interests.

Following on from Tony Abbott’s almost religious commitment to denying climate science, Scotty’s marketing backed up by his troop of puppets, buffoons, and knaves in Parliament have been for years almost totally successful in blocking any effective action against the climate emergency. This has been achieved through a rich mix of humbug, denial, lying, misrepresentation, blocking, delaying, and distracting smoke and mirrors.

If our children and grandchildren are to have any hope of surviving into the future, we have to remove the humbug troop from Parliament and replace them with sensible people who can be trusted to put action against the climate emergency at the top of their priority lists if elected. Vote Climate Ones, Traffic Light Voting System is designed to help you rank your preferences to do this, without telling you who you should vote for. With a new Parliament focused on what needs to be done to protect our burning house, we might be able to offer our families a viable future in a still functional biosphere.

Will they have a future in the world we leave them? That is up to us. If we get it wrong, it will be too late for them…..

Thawing permafrost in the Arctic warns we are probably crossing several critical tipping points on the road to runaway warming and near-term human extinction

William P. Hall on February 2, 2022

Part 6 of David Spratt’s guidebook to events along the road to Hothouse Hell: Burning Siberian tundra, taiga forests and peat soils are all contributing to thawing permafrost and pushing greenhouse gas emissions past an important tipping point

Spratt focuses almost exclusively on the consequences of permafrost thawing without much consideration of the overall environment of which the thawing permafrost is only a part. Even looked at in isolation it is clear that greenhouse gases are being released sooner and in greater quantities that in earth system models and conservative IPCC reporting.

I spent several months last year researching the interacting dynamics of the 2020 Siberian wildfires (burning taiga forests, arctic tundra, and even the underlying peat soils) on the underlying permafrost and the likely impacts on greenhouse gas emissions from both the burning overburden and underlying permafrost. None of the modeling has the full complexities of the likely internal positive feedbacks within this permafrost system. In other words, although all authorities seem to accept that the Arctic permafrost is a dangerous threshold we could already be tripping over, I think most still badly underestimate the dangers it represents for flipping us past the point of no return on the road to Earth’s Hothouse Hell climate state and global mass extinction.

Have tipping points already been passed for critical climate systems? (6) Permafrost: Beyond the models

Permafrost is permanently frozen ground. It covers one-quarter of the land mass of the northern hemisphere, and contains 1.5 trillion tonnes of carbon, twice the amount currently in the atmosphere and triple the amount emitted by human activity since 1850. Permafrost buried beneath the Arctic Ocean holds 60 billion tons of methane (in structures known as methane clathrates) and 560 billion tons of organic carbon.
Permafrost is releasing significant amounts of greenhouse gases, and feedbacks are under way, but the dynamics are not yet well enough understood to be able to judge whether tipping points have been reached or not. As previously noted (in part 1 of this series), University of NSW researchers point out that: “We do not know exactly how close we are to a tipping point, or even whether we have already passed it… There are tipping points that while not yet triggered may already be fully committed to.”
As permafrost thaws, soil microbes awaken and feast on the warming biomass, creating heat as they do so: a positive feedback that drives more defrosting. Russian permafrost scientist Trofim Maximov describes the global feedback: thawing permafrost releases greenhouse gases which cause warmer temperatures, melting the permafrost further: “It’s a natural process… which means that, unlike purely anthropogenic processes, once it starts, you can’t really stop it.”
A 2018 study estimated that stabilisation of the climate at 2°C may eventually result in release of 225–345 gigatonnes (GtC) of thawed permafrost carbon. That is equivalent to two-to-three decades of human emissions at the current rate. Some scientists consider that 1.5°C appears to be something of a “tipping point” for extensive permafrost thaw.

If rapidly thawing permafrost doesn’t sound the alarm that shouts, ‘Your house is on fire. If you don’t put it out your house will be gone!’ I don’t know what does. Unfortunately, in Australia we are living in a country whose national government seems to be a troop of wooden-headed puppets and knaves working for the fossil fuel industry. Here they are doing everything possible to drown out, stifle, and misdirect the alarm so it either won’t be heard at all, or will at least be ignored by the citizens they are supposed to protect and keep safe.

If we continue to follow the lead these puppets are trolling us with, nothing will be done to stop and reverse global warming until we are irrevocably committed to the Hell the fossil fuel industry is tipping us into. Think of the future when you decide who to vote for (and place last in your list of preferences) in the upcoming election. Hopefully, you will give your top preferences to candidates who can be trusted to put action on the global climate emergency at the top of their to do list if elected, and puppets of the fossil fuel and related special interests at the bottom of your list.

To help you, we are making available what we know about each candidate via our electorate specific Traffic Light Voting System.
