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.

Representatives of more than 50 nations gathered in Santa Marta, Colombia, this week at what was billed as the first global summit on phasing out fossil fuels. A panel of scientists will be advising them

Shipping and flights are the tricky ones because the energy density of fossil fuels is hard to beat, but we're still going to replace majority of those.

It's all in the works, just not happening fast enough. Net zero 2050 is still technically achievable, decarbonising electricity and lowering electricity prices is a crucial first step which makes other green solutions more attractive.
