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.

On Tuesday famed climate scientist Kate Marvel joined the more than 10,000 people with PhDs in science, engineering and mathematics who, according to Science, are reported to have left the U.S. federal workforce since President Donald Trump took office in January.

“I thought I’d spend my entire career working at this wonderful place,” her letter stated. But she “never expected that science itself would come under attack, simply because it—like journalism, history, and even the best kind of art—is a way of seeking the truth. I’m leaving because I want to tell the truth.”

But it turns out there are these older mass extinctions before the dinosaurs that were caused by huge eruptions of carbon dioxide into the atmosphere from these mind-bending volcanic eruptions. The one I focus on is the End Permian mass extinction. It’s the biggest mass extinction by far.
