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.

Escalating rhetoric comes as new study shows there’s just six years left to keep global warming to 1.5 degrees Celsius at current CO2 emissions rate

Graph showing increasing use of 'climate emergency' in academic literature from 7 examples in 2008 to 96 in 2018 to 862 uses in 2002.

There's no stopping this trend without nuclear energy. Renewable are great, but they can replace nuclear in 100 years. We need nuclear power now to replace greenhouse gas polluting power plants.
