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.

To be fair, Desantis immediately interrupted and said they weren’t going to raise their hands “like children”. No candidate would raise their hand after a comment like that. All their specific answers were certainly not climate friendly, but they are at least a little bit more nuanced than the title implies

Desantis didn’t have an issue raising his hand when the question was whether they would support Trump should he receive the nomination.

“Pick me daddy trump! Did you see how fast I raised my hand?”

I didn’t watch. Was it akin to a Bellamy salute?

He had probably already gotten his bit out of the way and didn’t know what to do hahaha

That's not nuance, that's an excuse.

That definitely still demonstrates a ride or die mentality. If one sleaseball can sway the room in such a way where than budging against it would lead to ridicule, that still shows the sort of internal pressure there is to tow the party line no matter what

And the dude on the far right of the stage started to, but then quickly lowered it when he saw there would be no vote.

But then some of them did on later questions, so... take that for what you will.

At least we seem to be progressing past the point we were at when Senator James Inhofe literally carried a snowball into the Senate as irrefutable proof that climate change isn't real
