Climate - truthful information about climate, related activism and politics.

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.

Echoing the other sentiments - We’re pretty hosed on this.

The forests in Canada aren’t going to un-burn themselves. And even if we could instantly stop emitting any more carbon, or start to decrease our emission levels, methane is being released via melting permafrost and early evidence indicates some self-reinforcement from that.

Our best bet is to do the best we can, try to get our governments to not listen to moneyed interests, and hope that technology breakthroughs and dumb luck slow down the speed of the transition to the point that humanity can safely migrate to climate havens and figure out how to build out infrastructure to cope with climate change, rather than go to war and exterminate ourselves.

But lets be real - fixing/maintaining things has not really been humanity’s strong point. We’re definitely going to mess up managing our mess up.
