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.

Its nice to see we're reaching a point where fossil fuels just dont make sense economically anymore.

You can politicise it all you want but if everyone makes more money by avoiding coal then thats how things are going to go.

Of course in this case Trump just wants to divert money to his friends, and he will probably succeed, but at least its getting harder and harder to do as the wins for renewables just keep stacking up.

My small city just announced theyre going to shut down the gas network in 3 years. Basically their modelling says that with reduced demand due to cheaper electricity from renewables and better electrical tech, no one will want to pay for gas.

Obviously its become a political issue, but its only going to get more difficult to argue against the economics as time goes by.
