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.

In our new study published in Nature Communications, we explore what the mitigation scenarios compiled in the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report (AR6) say about phasing out fossil fuels.

We found that, across all scenarios, global coal, oil and gas supply must decline by an average of 95%, 62% and 42%, respectively, from 2020 to 2050 in order to limit long-term warming to 1.5C with no or limited “overshoot“.

I feel like this is 1.5C thing is like the $15 minimum wage in the USA. It’s been so long and things have gone so poorly that we need new targets and ideas.

Yeah these people are looking at a fantasy. They're acting like this isn't a capitalist market and money is more important than facts most of the time.
