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.

It will be all of these and more, and it will continue to work to kill us slowly. Not a single event, but thousands over years, it has already begun and we're only accelerating it.

Some of us will survive to see the later parts of this century, but it will be a different world than pre-2000.

Heat has already been a killer.

Floods and hurricanes have already wreaked havok.

Water scarcity has caused deaths.

Ecosystems ravaged by humans are past their first stages of collapse.

And it's all getting worse.

We can try our best, but it won't be enough.

I just hope to care for those around me and try to spread good.

To help a starfish.
