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 for most purposes, when people talk about going to 2°C above what it was in the late 1800s, they usually are talking about the long-term average, not one-day events.

I thought making it plural made it clear already, but I wasn't just talking about this one article.

I'm also not sure where you got 2 degrees above average for a month? The article is about a single day.

Typo, I'm prone to them early in the morning.

TBH though if you look at the state of climate journalism and think it's alarmist, you're just a climate denier at this point. Anyways, if you're annoyed about climate alarmism, shouldn't you find a climate alarmist article to complain on instead of a reasonable, well-reported article on the matter?

I'm not having a conversation about shit I didn't say.
