Atmospheric Sciences professor at U. Utah. Believer that it really is turtles all the way down. Opinions predetermined and not my employer's.

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 .

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...

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

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.

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.
essopenarchive.org
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...

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.

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.

Wrote a paper a while back about how climate change should cause inflation. Poopooed for sure. Admittedly it was very big picture without a specific mechanism, but we're certainly seeing how now with increased insurance rates driven by e.g. the LA fires.

I developed an economic theory that underscores how energy and matter are the twin cornerstones of economic activity and growth, how mitigating climate change will require a fundamental restructuring of society. @fardos created this nice video about it.
