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...?

Glen, what are the uncertainties on the emissions? Could they be underreported for political reasons that introduce a flattened trend eg post Paris?

The monitor packaging said 50% brain capacity at 1500 ppm which seems exaggerated. I’m frequently 50% at much lower levels

I find I can do scientific writing up to 5000 ppm. 40,000 is what I read as the limit. Like non-vented gas fireplaces are widely sold. Seems like a bad idea to me but presumably there’s other reasons humanity cognition is cratering

I got my cabin up to 6000 ppm recently. Exercise in paleo time travel

Of course, but comparing numbers with different units is the sort of thing education is supposed to fix

Different units as one is annual. The two numbers can’t be compared as presented

Through a research program for undergrads sponsored by the Dean’s office I am able to accomplish research goals it would be harder to do otherwise through my grants, impossible through department overhead. Does the Dean’s cut matter if it’s well spent?

Can you elaborate on what that 10% of indirects you mention went towards? It's not obvious how the dean controlling the money is a problem.

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

Are there basic physical constraints on future anthropogenic emissions of carbon dioxide? - Climatic Change Global Circulation Models (GCMs) provide projections for future climate warming using a wide variety of highly sophisticated anthropogenic CO2 emissions scenarios as input, each based on the evolution...

YouTube video by Economic Growth and Collapse FAQ on the Garrett theory of economic growth

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. Here's a nice video produced about it

What do you mean clouds are heavy? As a cloud physicist that strikes me as an odd comment. Relative to what? Their density is on average the same as surrounding air

Human history is the tension between boundless exponential expansion and the harsh reality of resource depletion and pollution. Can innovation forever keep us afloat, or will nature hasten our demise? A new video:

FWIW I’m a professor of Atmospheric Sciences. This stuff is just a side gig. You should make your own content !

YouTube video by Economic Growth and Collapse The physical origins of economic Wealth

New video. Our economic models are unscientific: their assumptions cannot potentially be disproved. Starting ground-up from thermodynamic principles, we can build new economic models that make the testable predictions we need to guide our economic future

YouTube video by Economic Growth and Collapse The physical limits to economic growth

We must face the limits to our economic growth. Civilization thrives on high availability of energy and material resources, but at the cost of pollution and depletion. Traditional economics trivializes these constraints and risks hastening our collapse

YouTube video by Economic Growth and Collapse Humanity’s economic conundrum

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:

Economic Growth and Collapse

The basis is non-equilibrium thermodynamics, which may sound daunting, but these concepts underlie our lives. I think the animations led by Michael Fardos really help develop an intuitive understanding of economic growth and decline. I hope you enjoy

Key topics covered by the channel include efficiency, innovation, climate change, climate damages, energy and raw material resources, consumption, depletion, pollution, GDP growth, and economic inflation

The goal of the channel is to describe in a very accessible way some of the findings from work I've done describing how the global economy evolves, using concepts from physics rather than traditional neoclassical economic growth models

Economic Growth and Collapse

I'll be posting a series of videos on economic growth and collapse from this @YouTube channel spurred by Michael Fardos

Why oil rather than eg natural gas?

Economic Growth and Collapse

Check out this new @YouTube channel about economic growth and decline. Civilizations rise exponentially, only to become fragile as resources deplete and decay sets in. The path of expansion, discovery, and collapse seems defining. But can innovation sustain us?

The first five enabled humans to thrive to the point they harmed the last four. Science is great. It is also the engine driving our ability to consume and pollute at planetary scales
