The arc of history is long but it bends towards a lethally hot supercontinent 250 million years from now

@PeterBrannen1 New energy sources like renewables do not replace,or add, but rather they spur the old by encouraging overall systems growth. Unless it gets really hot…

“The Arctic Ocean became a net CO2 source…contributing to prolonged carbon input, temperature rise and ocean acidification during the PETM. These findings highlight potential major perturbations to Arctic carbon cycling under future climate change.”

💡What powers the world🕯️ Humanity's energy demands are constantly increasing, relying on a growing supply of fossil fuels & "renewable" energy."Civilization grows by efficiently using an energy surplus to transform the earth's crust into the stuff of us" x.com/nephologue/sta…

In a world sustained by combustion, even just maintaining the GDP at current levels accelerates CO2 emissions and the rise in concentrations. To stop this either: 1. We proactively collapse the economy now, or 2. Wait for climate change to do it for us later🧵

We just checked and there’s still no snow in the forecast.   In the 1940s, the study of snow science and avalanche mitigation in North America began right here at Alta, thanks to the work of intrepid USFS Snow Rangers. 🎥: Sverre Engen 🤠: Monty Atwater and Ed LaChapelle

@Rob66733000 Current concentrations are determined far far more by past emissions than current emissions (or their changes). That's why the plot is actually a little non-obvious to interpret. Also, the US isn't isolated from trade. If "offshores" emissions to e.g. China

@nephologue Yes, and the US now contributes much less relative to GDP. US leveled off near 5 billion tons, while developing, but the remainder of the world didn't do its part. Today US is abt 13% of CO2, but 30% of global GDP.

Not the first time I've posted this, but I always find it quite fascinating how well it continues to hold. For over *two thousand years*, atmospheric CO2 perturbations have scaled with the world GDP. Aren't the implications for climate change mitigation pretty simple...?

@Rob66733000 Emissions aren't concentrations. And from the atmosphere's standpoint, only global emissions matter

@nephologue Not all countries follows linier over time. US has reduced its carbon/GDP by a factor of five since it peaked 100yrs ago and continues to go lower.

@Revkin Yes, this is fundamental to the larger point I argue academically, which is that civilization can be modeled deterministically, like a superorganism growing as any other into available resources, driven by a balance of depletion and discovery as the resources are there to exploit

This could be better framed as asking “what will the OBBB bill do for the global economy?”. The global economy is stably carbon based. So, if it hurts the economy through idiocy then it reduces CO2 emissions
Jesse D. Jenkins@JesseJenkins

Compared to what Trump can do via executive action alone, if the Senate-passed #OBBB becomes law: 1. US greenhouse gas emissions would increase by ~190 million metric tons per year in 2030 & 470 million tons in 2035

@oikeios CO2/GHG are the waste products of a combustion-driven & interconnected civilisation and must be addressed globally. UK emission cuts are irrelevant amid rising global CO2 levels.what Arnaud as a China Lobbyists is defending is the growth paradigm. x.com/nephologue/sta…
Tim Garrett@nephologue

We're collectively growing at an extraordinary pace of about 2.4% per year, fast enough to add as much to our daily resource demands in the next 30 years as we have since the dawn of civilization. If you feel it's hard to keep up, there's a reason... 🧵

@YvanDutil At the time of power generation, yes. However, there are dynamic feedbacks in the system that I believe cause renewables to spur fossil consumption, by powering the material construction of an energy hungry civilization that must increasingly be fed whatever the power source

@nephologue Les renouvelables, c'est bien, mais sans réduire notre appétit énergétique, on tourne en rond. La sobriété, c'est la clé !

@YvanDutil True. That part is discussed often, legitimately. The role of the recent additions of renewables less so
