giving impressions of doing something by catching pies in the sky and capturing bananas...“I will not sacrifice Great British industry to the drum-banging, finger-wagging Net Zero extremists,” was the headline The Sun in London gave to a piece last week by Prime Minister Sir Keir Starmer, defending the expenditure of 22 billion pounds on the cargo cult of carbon capture and storage. This headline captured the delusion at the core of climate-policymaking around the world: that there is an economically non-disruptive path out of the climate emergency. There isn’t. Entering an age of social and security consequences By David Spratt
Either we close down the fossil fuel industry long before its physical infrastructure is exhausted, strand a whole lot of capital and engage in a non-incremental restructuring of work and the economy; or we will have a world of social breakdown, conflict and economic chaos. This was the picture painted by US analysts 17 years ago in a study titled The Age of Consequences, which warned of the damage at 2.6°C of warming, a target we will likely exceed on present indications: “Massive nonlinear events in the global environment give rise to massive nonlinear societal events… nations around the world will be overwhelmed by the scale of change and pernicious challenges. The internal cohesion of nations will be under great stress both as a result of a dramatic rise in migration and changes in agricultural patterns and water availability. The flooding of coastal communities around the world has the potential to challenge regional and even national identities. Armed conflict between nations over resources is likely and nuclear war is possible.” And the lead author of that report? Kurt Campbell, now the US Deputy Secretary of State. Political stability is significantly built on a fragile social compact in which the state delivers some measure of social and economic progress for the population, and the population tolerates the political process. Failure to deliver — even on the basics such as food security — may result in large-scale political disruption, of which the Arab Spring of the early 2010s is just one example. In Syria, an epochal drought and a climate-driven spike in global wheat prices were factors that led to revolt, state failure and civil war. Social compact failure can be seen around the world today because decades of neoliberalism have resulted in the vast transfer of wealth to the elites and stagnation or declines in living standards and real wages for most people, misnamed a “cost of living” crisis. Too often this has led to racist, populist and authoritarian responses and a growing disenchantment with a politics that is no longer seen as delivering for most of the people. Hence the rise of the Right in Europe, Trumpism, Javier Gerardo Milei in Argentina and so on, aided by the collapse of once social-democratic parties captured by neoliberalism and the fossil fuel industry. Climate change has and will disrupt the social compact even harder by squeezing the fiscal capacity of the state to deliver on the basics. Economic disruption and dislocation will become the norm, in multifaceted ways, reducing GDP and state revenue and/or requiring ever greater expenditures to repair what a more extreme climate has destroyed or to prevent even greater damage.
All these factors will weaken the state’s capacity as more and more state revenue is diverted away from social and service delivery into climate responses. This will further reduce the standard of living and fuel economic grievances, social unrest and right-wing populism. At some point, these economic pressures will also lead to state financial insolvency and/or collapse; and perhaps also to major dislocations in the global financial system. Climate vulnerability will increase state sovereign risk and the cost of capital, reducing the capacity to access the resources to fight climate disruption. The greater the climate impact costs, the more likely is the collapse of the social compact, with consequences including further economic disruption and a growing incapacity of the state to finance increasingly large climate mitigation and adaptation budgets. That failure will in itself worsen future climate impacts, in a climate–economy–disruption feedback loop. Climate impacts, especially in the dry subtropics, have already been a driver of social conflict, insurgency and war, including across the Sahel and in the Middle East. Growing authoritarianism and the likely plunge towards militarism and war will further decrease the capacity of states around the world to deliver on the basics because:
This may also be a feedback loop where the increasing securitisation of climate consequences will have an adverse effect on the capacity of the state to maintain a coherent community with adequate delivery of basic services. At the level of warming the world is presently heading towards — 2.5 to 3°C — economic disruption and crisis will be endemic. “2.7°C is without any doubt a disaster. It’s a point we haven’t seen for the past 5 million years. There’s no evidence that we can support humanity as we know it on a 2.7°C Planet,” says Prof. Johan Rockström, Director of the Potsdam Institute for Climate Impact Research. US President Joe Biden disagrees. On 1 September he tweeted: “On my watch, we’ve responsibly increased our oil production to meet our immediate needs – without delaying or deferring our transition to clean energy. We’re America. We can do both” (emphasis added). Sounds like our Prime Minister, too. https://johnmenadue.com/entering-an-age-of-social-and-security-consequences/

over the limit....
Temporarily overshooting the world's current target for limiting global warming could still result in dire climate outcomes, such as rising sea levels, which are irreversible on human timescales, according to new research.
An analysis of internationally accepted scenarios for limiting average global temperatures to a 1.5 degrees Celsius rise compared to pre-industrial levels, published today in Nature, suggests reversing the consequences of peak warming may take decades.
Staying under the aspirational target of 1.5C by 2100 has been modelled as possible under several scenarios by the United Nations' Intergovernmental Panel on Climate Change (IPCC).
Some of these scenarios include instances where the target is temporarily exceeded in the next 80 years before stabilising by the end of the century.
But study co-author Carl-Friedrich Schleussner said there was overconfidence in overshoot models to reverse temperature rises and their consequences.
"We find that 100 years of overshoot above 1.5C would commit about an additional 40 centimetres of sea level rise in the long run," Dr Schleussner, a science adviser at the not-for-profit climate science institute Climate Analytics, said.
"For some low-lying places, this could well be the difference between having a possibility to adapt and having to ultimately concede and migrate.
"Any potential temperature reversal after overshoot will take decades. That's much longer than the time horizons normally involved in adaptation planning."
Examining the unknowns of climate scenariosThe study, which involved 30 scientists from several international institutions and organisations, sought to better understand the uncertainty in just how high temperatures could peak in the event of an overshoot.
Imperial College London climate scientist and study co-author Joeri Rogelj said an additional 0.1C in overshoot scenarios might sound manageable, but this was only a median figure.
The study showed — based on the IPCC's own assessments — that there was a one in 10 chance warming would exceed two degrees in an overshoot.
"Instead of being able to reverse warming, we might need substantial amounts of carbon removal to stop warming from increasing further in the first place," Professor Rogelj said.
Exceeding the 1.5C target increases the risk of the Earth systems passing critical tipping points, such as melting permafrost or continued sea level rise for centuries to millennia.
The study found every 100 years of overshoot above 1.5C would result in an additional 40cm of sea level rise, on top of a baseline increase of 80cm, by 2300.
Global warming may also produce further warming: an additional 0.02C could be generated by melted permafrost every 100 years of an overshoot, according to the research.
What about carbon capture and removal?Many of the IPCC's 1.5C overshoot scenarios rely on carbon dioxide removal to meet the world's 1.5C target.
Carbon dioxide removal includes initiatives such as reforestation or direct carbon capture for high-emission fossil fuel developments.
Professor Rogelj said the world may need to consider more substantial carbon dioxide removal under the overshoot scenarios than had previously been modelled.
But he said there was also an overconfidence the world could achieve the level of carbon dioxide removal already assumed necessary.
Australian National University climatologist Mark Howden, who was not involved in the study, said there was a lot of attention on direct carbon capture which was feasible, but costly, and small in scale.
"We could invest in this significantly but it is likely still to max out at around 2 gigatonnes of carbon dioxide per year."
Professor Howden said there was an imperative to pursue emissions reductions rather than carbon capture, given the world produced about 40Gt of carbon dioxide every year.
Wageningen University climate policy scientist Niklas Höhne, who was also not involved in the study, said the research showed there was uncertainty around whether temperatures would decline if carbon dioxide was removed from the atmosphere in the second half of this century.
"Knowing that damages can already be extreme at [the] current temperature increase of 1.3C … the paper is a plea to reduce emissions as fast as possible immediately," he said.
"Much faster than currently planned by national governments."
The world is fast running out of its remaining carbon budget for staying under 1.5C.
A recent study in Nature Climate Change suggested the best outcome the world could now reach by 2100 was 1.6C, and that was using the most ambitious mitigation pathways.
Ultimately, the lower the world can keep peak warming, the lower any additional unknown risks from temperature increases there will be, Professor Rogelj said.
