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.

Tornadoes Are Coming in Bunches. Scientists Are Trying to Figure Out Why. The number of tornadoes so far in the United States this year is just above average. But their distribution is changing. (www.nytimes.com)

While the timing of this trend lines up with the planet’s rising temperatures, scientists are hesitant to definitively attribute tornadoes’ clustering behavior to human-caused climate change.

“The link between climate change and tornadoes is still pretty tenuous,” Dr. Fricker said. “It’s a really open and difficult question for us.” One difficulty is that tornadoes are too small on a planetary scale, and too ephemeral, to show up in the global mathematical models that scientists use to study climate change.
