Thread: New paper in @EGU_ESD with @ProfSteveKeen and @prof_grasselli shows a 50-year fixed relationship between world economic "wealth" - not the GDP - and global primary energy consumption. Implication? Our future is tied to even our quite distant past https://t.co/LxK79jba1v

Abstract. Global economic production – the world gross domestic product (GDP) – has been rising steadily relative to global primary energy demands, lending hope that technological advances can drive...

“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.”
Article: Enhanced aerobic oxidation of methane in the Arctic Ocean intensified carbon dioxide emissions during the Palaeocene-Eocene Thermal Maximum, potentially extending the event @MethanoClimate @ChemClimatology

💡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" https://t.co/uhceecF2Jl
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

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...?

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
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

Latest news: We need to return to 353 ppm CO2 to restore the energy balance and stop global warming https://t.co/pSBcuvS2DB That requires rewinding civilization energy demands back to 1960. https://t.co/rq5icoQlvV Good times ahead.

@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.
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... 🧵

When will we draw a link between an accelerating rise in CO2 emissions and the surge in renewables? Renewables do not replace, they do not simply add, but by catalyzing the construction of a hungry civilization, they spur
Jaw dropping: "Not just a little record, but 25% higher than the previous record."

"A potentially more concerning explanation for the drop in cloud cover is an emerging low-cloud feedback, whereby low cloud cover decreases with rising temperature, which...could lead to more future warming than currently anticipated"

The neoliberal dream of fossil fuel billionaire Charles Koch was always the destruction of US democracy and the elimination of government (except for its repressive organs police, courts, prisons, military ofc), and now he has won. What now? A short 🧵. 1/ https://t.co/FKxxmLyfce

Big graupel and water totals at Alta today. Peak hourly water equivalent so far is 0.41" The record at that site is 0.54" from 10-11 UTC 5 Jan 2008. Radar image below. Snowfall generated over the Alpine Ridge in a southwesterly atmospheric river just ahead of a cold front.

In 2017 at a small meeting in Switzerland on energy and the economy, experts scolded me that the economy would collapse from resource depletion and debt, certainly by 2025. I argued inertia would keep it growing longer (not forever). Here we are. Physics actually works! Always.

So it turns out snowflake settling is full of surprises. Not just size, not just shape, not just density, not just turbulence, but perhaps more than anything it is the mean wind horizontal winds speeds that controls how fast snowflakes fall https://t.co/7drtiobsSb

Numerical model predictions of precipitation rates rely heavily on representations of how fast hydrometeors fall, assuming settling is determined only by the opposing force balance of gravity and...

Civilization grows by efficiently using an energy surplus to transform the earth's crust into the stuff of us. However, growth has limits. Resource depletion and internal decay will tip us towards collapse. A new video: https://t.co/iPewE4tAI8

The major problem that humanity faces is the persistent failure to understand that we’re fundamentally no different than any other system in the universe
the major problem that humanity faces is that we are really bad at foreseeing and, if necessary, correcting the emergent collective trends of individual actions in the context of the systems we have created for our interactions

There will be intensifying constraints on growth, and deepening uncertainty. Ultimately, you cannot make an unsustainable system resilient -by definition.
Low growth and higher uncertainty pose new challenges for monetary policy in the euro area, says ECB Vice-President Luis de Guindos. And in this environment, preserving the strength and resilience of euro area banks is crucial.

I’ve argued for some time that a kid with a ruler would do as well as complicated climate/societal models predicting rates of temperature rise. Turns out I was wrong. No wait! The models didn’t predict it either… hey kid, got a moment?
Both 2023 and 2024 were significantly warmer than we'd expect based on the approximately linear rate of warming (and variations around that trend) the world has experienced since 1970. It is further evidence that the rate of warming may be accelerating.
