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.

The latest flooding is a reminder of how even the ruling Communist Party struggles to tame the unpredictable weather gods.

“Climate change is another motivating factor for China to focus on food security,” said Darin Friedrichs, the agriculture market research director at Sitonia Consulting. “A common idea in state media and official speeches is the idea that, given its size, China cannot rely on other countries to feed it through imports.”

Glad to see their talking points focus on food security rather than agricultural companies' interests like the EU. Though I wonder if they'll come to the sensible conclusion and cut down on the meat industry.
