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.

More nefarious than that IMHO. The science community works on consensus.

So when we say temperature will rise by 2.5 degrees and we are fucked That's the number they all agreed on.

99% of scientists may agree that a 1 degree rise means we are fucked. The 1% says 3 degrees. So if big business or shit government gets to that 1% they can control the narrative around what is socialized.

I'm a child of the 70's. Scientists have been ringing the warning bell for decades. Look at how ocean acidification is swept under the rug in all climate discussions. Scientists know it's a huge problem and has been since at least the 80's but do ALL scientists agree we are fucked?

If I was a scientist I'd be so damn jaded at the state of the world.

At least we can all be happy we are helping people get rich. Thats what is important after all.
