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.

I'll note that there is no legal basis for the claim of "emergency" here, US fossil fuel extraction has already been at a record and additional extraction is simply exported

President Donald Trump signed an executive order last week to end the federal procurement of paper straws. 

The order, which claims that paper straws are “nonfunctional” and says it wants to end the “forced use” of them, immediately undoes part of a Biden-era initiative to eliminate single-use plastics, including straws, in all government operations by 2035. More broadly, Trump instructed White House staff and “relevant agencies” to issue a “national strategy to end the use of paper straws” within 45 days. The strategy would aim to eliminate all executive branch policies “designed to disfavor plastic straws” and address the federal government’s contracts with states and and other entities “that ban or penalize plastic straw purchase or use.”

Bill Gates presents himself as a climate champion, but his trust has actually increased its fossil fuel investments since his divestment pledge. It's just the latest example of the billionaire appointing himself to solve problems he helps perpetuate.
