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:

We're headed for 3 or even 4 degrees. The version of 'deep fast cuts' We're getting is data centers burning through seas of diesel, corruption stomping on clean energy progress in favor of petro-corp profits, and a global consumer base willing to save the planet, but only if they can sacrifice no comfort or convenience in the process.

We are heading for 3 degrees by 2050, that much seems pretty certain and baked in now. Past that is murky but given how little action has been taken so far it seems we will probably speed run up to 6C by 2100. Throughout this entire period we have followed the worst case scenario that everyone called unrealistic. Turns out the IPCC has been underplaying the impact of CO2 for 50 years. Humanity can't change, unless we have a technological breakthrough this ends with only millions of humans left and most species on the planet extinct.
