Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Taking CO2 out of the air would be an absurdly expensive way to fight climate change (www.theverge.com)

I wonder how expensive the damages from climate change will be.

across the US. Big companies including Microsoft and Amazon are also paying startups to capture some of their pollution. And the fossil fuel industry has embraced the technology, even using it to market supposedly more sustainable oil. Apparently, that still isn’t enough.

“More sustainable oil”. Sure dude. Just keep doing the same thing you’ve always done that cause this problem in the first place. But wait…

There are so many limitations to the most studied CDR techniques — including tree plantingand** machines that capture CO2 **— that Romm says the money would be better spent researching other ways to reduce greenhouse gas emissions.

Oh, so do nothing while things keep getting worse? We need to hemm and haw over the things we haven’t thought of that will also be too expensive?

But why put a Band-Aid on the problem if we aren’t stopping the bleeding?

Well, because it’s not a perfect solution we should do nothing is the gist I’m getting from this whole thing. Other than what we’re already doing - attempting to lower emissions.

Lowering emissions doesn't increase shareholder value. Try again, and this time think of the shareholders.
