Climate - truthful information about climate, related activism and politics.

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.

The action is one of the Biden administration’s strongest against the fossil fuel industry under provisions of a 2022 climate law

Pessimistic as I am, the combination will be fees that are cheaper than fixing the problems as well as passing that extra cost on to the consumers. It's better than nothing, but I usually find that phrase used when a lot more could have been done but wasn't because it was good enough to quieten some of the noise.

I forgot another possibility - lawyers and lobbyists to neuter any actual teeth the law ends up having.

Also, I have to put out the reminder since the "80x CO2 greenhouse effect" was used - that half life average (still used by many including the IPCC) isn't all that valid if methane emissions continue to rise. It gets worse as methane breakdown/methane addition ups the total amount at any given time.

The fees, starting at $900/ton and rising to $1500/ton are high enough that it's a lot cheaper to fix leaks of any size.

Lol you're forgetting that oil companies will be expected to self-report on excessive methane production.

EPA, the State, and independent certified authorities can do inspections by satellite, plane, tower, and from their vehicles on the road.
