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.

Assuming el nino ends, it should be a bit cooler once that happens. But eventually neutral or la nina years will surpass this year's heat.

Though considering the 20 - 30 year lag between creating emissions and feeling their impact, we've still got at least a decade of accelerating heating before it settles into a more constant increase corresponding with emissions plateauing in the 2010s--oh nm, that was just a temporary plateau, it started increasing again during the late 10s. But maybe we're at the peak now and will see the acceleration of heating stop in 20 - 30 years.

I feel like I just read el nino is over a few days ago.

Yeah, it looks like it is weakening. It's not quite over atm but it's close.
