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.

Young Democrats...didn’t vote

In 4 of the 7 key states, Harris received more votes than Biden did in 2020. In the 3 where she received less, Trump still would have won based on how many more votes he got even if Harris's vote count was unchanged compared to Biden in 2020.

This "Democrats lost because of Gaza" angle is convenient. Both sides like it use it. "Moderates" like to blame the "far left" for discouraging voters by calling out the inaction on the genocide. Leftists blame the moderates because they refused to actually denounce the genocide or commit to stopping it. Both side's arguments are based in assumptions that do not bear out once you look at the actual votes.

I mean a whole lot of voters did put the biggest reason they sat out as Gaza. There was a poll on it by YouGov. Now let's not get that wrong; Harris lost because her campaign was a shitshow, so blaming Gaza voters in particular is improductive, but even with a moderately good candidate it would've probably been close as they would've had to win without Michigan and Arizona.
