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 cold needs to stay in the Arctic. Instead it is being mixed with warmer air in the mid latitudes. That makes the Arctic warmer and my arse cold AF.

People think it is cold, not realizing that someone is leaving the freezer door wide open.

It feels cold now, but once the arctic loses all that ice, things will heat up quickly.

But no one is going to care unless it effects them. People thinking global warming is coming for them 15 years from now are going to be surprised when the effects are felt 1-2 years from now.
