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.

“Over a dozen young Americans as well as a coalition of environmental and public health groups on Wednesday filed a pair of legal challenges against President Donald Trump’s administration for repealing the “endangerment finding” that enabled federal policies aimed at combating the fossil fuel-driven climate emergency.

“Environmental Protection Agency Administrator Lee Zeldin announced the long-anticipated move last week. The coalition of groups responded with a petition at the US Court of Appeals for the District of Columbia Circuit that names him and the EPA.

“”The endangerment finding has been the backbone of climate policy for 17 years, protecting us from air pollution that endangers public health and welfare—including greenhouse gases that are driving climate change,” explained Lawrence Hafetz, legal director at Clean Air Council, one of the groups behind the case, in a statement.”
