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.

If they censor the news, no one will notice when Galveston floats away...

Isn't Galveston the site of the worst natural disaster in US history?

So we had to sacrifice the planet, big deal.. the rich will be just fine. /s

The rich will be fine for a bit longer. But once economies collapse, even their money will be worthless. How long until their private security people realize who holds the real power?

I do at least appreciate that Texas and Florida are getting it the worst.

There was an excellent allegory for this from Tamino many years ago that stuck with me. For those not in the know, he's a statistician who works with climate scientists (amongst other things) like Professor Stefan Rhamstorf

https://tamino.wordpress.com/2016/02/03/how-to-destroy-a-megalopolis/

In fact I did it every day. One large pot of boiling hot water. The idea wasn’t to kill all the ants, or to eradicate their megalopolis in one crushing blow. The idea was simply to make it too costly, in terms of energy and time, for their complex of ant cities to be sustainable.

It worked.

After about two weeks, the ants were gone. Completely. I believe they just couldn’t stay there any more, it was just too difficult with such regular demands on repair. I don’t know whether the megalopolis died out, or they moved to a different location. But any way you look at it, I succeeded in destroying their megalopolis, because amid the continual assault of disasters, they simply weren’t able to keep up.

This is what can happen to us. Global warming isn’t going to come in one astounding assault and kill us all with one blow. It’s just going to make survival harder — a lot harder — with regular assaults like floods, droughts, heat waves, killer storms.
