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.

Unregulated carbon offset tokens are nothing but greenwashing.

You can buy a clump of forest and sell carbon offset points because “you have a forest that offset carbon”, but if you didn’t buy the forest, due to zoning laws, it would still be a forest.

Or alternatively if zoning permits you cut it down a year later. But you still made heaps from selling “carbon tokens”.

It goes beyond that. You threaten to cut down the forest unless someone pays carbon credits to save it. Then 5 years later you do it again.
