Thanks for nothing
While humanity may not survive a doubling of CO2, economists assume that unsurvivable futures can be treated as essentially trivial costs, barely worth talking about.
Policy over the past 30 years acted as if this weren't insane. Now, the window of action is essentially closed. What else is there to say?
Fair point that some lifeforms, mammals & humans may survive even an end-Permian-like supercharged new mass extinction. Just not humanity in its present form, which is what matters for most of us. This isn't a paper exercise, we talk lots of lives here.
What’s messing with my perception of reality is that economists have so completely lost touch with global dynamics. 1.5°C by 2030 is locked in by past emissions, and rapid decarbonization would even accelerate warming. At some point we need to move beyond kindergarten dynamics

Current climate research and policy remain shallow and caught in optimist groupthink at every layer. What we should be asking: will we go to war to decarbonize other countries? Urgent, entirely open questions that international law is unprepared to answer.
We've been warning for years that current climate policy is naive as it doesn't reflect thermodynamic and political constraints, and doesn't take its own warning seriously. Extremely glad @MuellerTadzio is writing a book about peaceful sabotage: #friedlichesabotage
Some have been asking these questions, but at the risk of their own reputations and resources: @RoyScranton @scholarswarning etc. Our institutions lack the expertise in science, engineering, and humanities to prepare for what's ahead. newrepublic.com/article/157160…

"Fundamentally, the economists have totally misrepresented the science and ignored it where it contradicts their bias that climate change is not a big deal because, in their opinion, capitalism can handle anything," —incredibly important warning by @ProfSteveKeen
“the repercussions of climate change were foretold in the 1972 publication “The Limits to Growth” — a divisive report on the destructive consequences of global expansion — but economists then and since failed to heed its warnings, preferring instead to rely on market mechanisms.”
“I think we should throw the economists completely out of this discussion and sit the politicians down with the scientists and say these are the potential outcomes of that much of a change to the biosphere; we are toying with forces far in excess of ones we can actually address,”

Is macroeconomics a science? Many of our problems come down to our misuse of economics. Accessible starting point for impactful analysis: @nephologue nephologue.blogspot.com/2018/08/is-mac…
Why this matters: Economics evolved for a growth regime, not for a full world, that approaches biophysical limits to growth. To share + accentuate @KevinClimate's concern: Do the physical climate sciences reflect & address the limitations of economics yet?
Can we learn to use economics in better, more humane ways?

This questions goes beyond natural sciences & engineering: many social scientists, & scholars in the humanities, routinely use sophisticated quantitative & qualitative toolboxes. Let's use them where it matters 🙏

and love this writing. Whoever said academic writing must be boring. Ocean acidification vs. Plastic pollution — the battle is still David vs. Goliath, but this dramatically improves the odds... /#Plasticene Image

The feedback structures in high-order nonlinear feedback systems persistently draw attention away from high-leverage points (social change), towards low-leverage points (technology, consumption).
We need to learn to distinguish symptoms (greenhouse gas emissions) from causes (structures that generate activities causing direct or embodied GHG emissions). Yet most sustainability and climate science focuses on symptoms that cannot possibly solve deeper structural problems.
just a quick reminder to whomsoeverhereontwitter it concerns that when we call out <deep structural systemic problems that currently have no solutions> that may sound like 'giving up' to y'all (but just because you read shallowly); I never say that, it's lit a problem of language

To atone for past sins, I'm reading Jay Forrester and am sorry to report that where I google, past people *thought*
That's sobering 😂 (here: World dynamics 1971) 🥰
Useful 2016 review of the LTG discourse: @appg_L2G limits2growth.org.uk 🙏
