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.

Temperatures are rising as summer kicks off, and psychological scientists are sounding the alarm on what to be aware of in warmer temperatures. It remains to be seen whether summer 2024 breaks the records of last summer: In the United States, heat domes baked the Midwest; El Paso, Texas, saw weeks without a day below 100°F; and Tampa Bay, Florida, issued its first extreme heat advisory. In November 2023, Phoenix reported that at least 569 people had died because of heat-related reasons over the summer.

Extreme heat days are an inevitable consequence of a warming world, and things are not cooling down. Globally, 2023 was the hottest year on record, and the Met Office—the United Kingdom’s national weather service—predicts that 2024 may be worse. It could even be the first year on record to surpass 1.5°C of warming above the preindustrial era.
