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.

Ironically, New Orleans might be OK because we have elaborate flood control systems and have always dealt with flooding. Vulnerable places like the Netherlands and New Orleans are what we all assume will end up flooded. (And we will.)

But we’re built for it. A river delta floods sometimes anyway. I’m honestly more worried about places where snowmelt creates small streams now but in the future, will just create terrible floods every Spring and then draught immediately after.

To me, the scary part isn’t having water in the streets. It’s climate change. We had an issue recently where there wasn’t enough fresh water draining into the Mississippi to push the salt water back. It ultimately never reached NOLA but it reached plenty of people downriver. And because of a drought in the Midwest.
