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.

Instead of essentially requiring automakers to rapidly ramp up sales of electric vehicles over the next few years, the administration would give car manufacturers more time, with a sharp increase in sales not required until after 2030

...

Ali Zaidi, Mr. Biden’s senior climate adviser, declined to discuss the details of the final regulation. But he said in an interview that Mr. Biden’s climate policies, combined with record federal investment in renewable energy, would still help to reach the president’s goal of cutting the country’s greenhouse gas emissions in half by 2030.

Plenty of time for the administration to benefit from making the promises, but not actually still be in power when it comes time to see if they follow through.

Sorry not an American, but why are the unions pro combustion engines? Seems like they want to loose their jobs to cheap import evs long term.

They work for car companies which came late to EVs (Tesla isn't unionized) and are afraid that there will be fewer parts in electric cars, and therefore less labor involved in building them. So management can stampede them into doing their bidding.
