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...?

1-According to the Global Carbon Project, global CO2 emissions from fossil fuels and industry decreased by approximately 6.4% during #Covid in 2020 compared to 2019. This was the largest annual drop in emissions since World War II.....

6- Despite efforts to chart a course towards a sustainable future, there are inherent physical constraints that cannot be ignored. Our world operates according to fundamental laws of physics, and any attempt to divorce society from these natural laws .....

If I lose my job for speaking out, for speaking the truth, for standing up for all that is good, it will be a badge of honor

Joined @racheldonald.bsky.social on Planet Critical to talk about the rot in Silicon Valley

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

Cannot stop thinking about how Octavia Butler wrote a book in 1993 about climate change. It opens with deadly fires in LA in 2025. In the story, a fascist President has just won office with the campaign slogan "Make America Great Again."

She was a modern day Nostradamus. If only we'd listened.

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:

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

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

What's the relationship between our energy consumption, our material footprint and our economies?

I spoke with the funnest physicist I know @nephologue.bsky.social to find out.

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 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
www.youtube.com/channel/UCA6...

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

I'll be posting a series of videos on economic growth and collapse from this @YouTube channel spurred by Michael Fardos
www.youtube.com/channel/UCA6...

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:

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
