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.

The Arctic region has been a massive store of carbon for thousands of years. Now it's warming between 3 and 7 times faster than the global average and that carbon is escaping into our atmosphere. The latest research suggests that more than a third of it is now a net emitter! And in case you're wondering...that's NOT good!

To be fair to the Boomers, there has been more change in the last 50 years then all of human history combined. Also, there are errors that even (especially?) the intelligentsia are prone to. Also, Rome fell as well - so even though it happened on their watch, wasn't it inevitable, really?

Certainly I have made mistakes in my own personal lifetime, and I would hate to find out that ending civilization was one of them (but in fairness, it very well may be part of the issue). Like, what if 20 years from now, we were to find out that using Lemmy will have put an end to the freedom of people being able to use the Internet, bc of so many messages about Luigi that kept getting powerful people killed, so "they" start banning the protocol and going after it harder than they ever did piracy (which has always been more of a nudge wink just don't let it get out of hand situation)?

All we can do is be as responsible as we know how to be.
