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.

“Any additional greenhouse gases that might have been released by Australia as a result of low emissions targets would have caused no more than an almost immeasurable increase in global average temperatures,” Wigney said.

Ah yes, the Noone Is Responsible problem. Noone could individually fix it so none of us are obligated to do anything. Future is looking bright.

British / Australians claim ownership of the land, Australians siphon out taxes from aboriginals, but also Australia isn't obligated to them.

Governments around the world continuing to prove that collective action from the people is the only path forward.

The government should be obligated to shield them from the causes of climate change. But I suppose that ship had sailed.
