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.

The article said “.25 - 6 hr per day”. I interpreted that to mean 1/4 of the day (6 hours). While not as good as 24 hours, it is definitely not a paltry 15 minutes.

Between 15 minutes and 6 hours of the day per the tweets from the prof the article posts about.

I know the tweet I'm linking is quoting the article, but it's the prof quoting the article stating the range, so I take that as an endorsement of the validity of the range.

Thanks, that makes sense.

To add on to what NegativeInf said and linked, "0.25" is a weird way to say a quarter of a day. It makes more sense, to me, that the zero at the front was left off and it should read "0.25-6 hr per day".

Yeah, I agree; my brain went off into left field I guess.
