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.

How is that possible? We banned it. We had a whole vote on it any everything.

Plus it's not even real. It snowed just last winter.

I have some thoughts on that river, which I visited often and heard the stories.

It always floods, and there are always drownings. One would think from reading the headlines that it’s a very tame river which did this surprising thing.

And it was a particularly bad storm, at a bad time of night, on a bad date ( the holiday) and climate change made it worse and/or more probable.

But places on that river have always flash flooded. And the water has raised that much before, that fast. And looking back, it has sometimes flooded at night during holidays.

The only difference is that more people now live there than before; more camps and buildings were allowed to be set up in bottom lands, in the flash flood areas . And more people, new to the area, were ignorant of its dangers.

Its also the case that this kind of sudden intense rain is more likely in a warmer world, and that local and state politicians were unwilling to either restrict development in the floodplain, or even set up the kind of warning system which would let people evacuate

Yes, all three, it’s a slow creep that can catch people unawares

Thw entire thing is weord becase climate change plays a part in EVERY weather event. The quetion is, how much it goosed it froma baslen of 100 years ago..

Even thats mostly irrelevant because ... All we're doing is making it worse.
