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.

TLDR, they are focusing more on the newer technology found in Stratos that pulls CO2 from the air vs Century, the 13 year old plant, that gets it directly from emissions generated from a gas plant. And that gas plant hasn't been producing enough for the Century plant to be cost efficient.

This not a climate change article. It's an investment/economics article about Occidental Petroleums outlook and market performance in its attempt to make Carbon Capture a very profitable business.

Here's the thing: in almost all cases, it's cheaper to not emit in the first place than to pay for carbon capture. So the economics of it actually matter quite a bit.

Yeah, this is the sneaker. Unless they're powering carbon capture with green energy or perpetual motion (spoiler alert), they're basically burning a whole lot more carbon to claw back a little already emitted carbon.
