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.

Jensen Huang, the CEO of supercomputer chip-maker Nvidia, has for years claimed that his company’s artificial intelligence products, as some of the most advanced scientific tools in history, will help the world solve climate change, warning last year that “climate disasters are now normal.”

Yet Huang is now loudly cozying up to U.S. Energy Secretary Chris Wright, even though Wright is fully on board with the Trump administration’s climate denial policies.

A so-called “climate science” report Wright’s Department of Energy released in July has been condemned by scores of scientists as “biased, full of errors, and not fit to inform policymaking.” The report is part of the administration’s effort to overturn the scientific basis for regulating greenhouse gas emissions as pollution — the 2009 endangerment finding — under the Clean Air Act.

Remember that joke about asking an AI to solve traffic, and when it responds with "Use trains" the user declares it must be broken?

"Stop burning fossil fuels and reduce emissions? That can't be right!"
