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.

I'll note that while methane is responsible for something like 30% of the observed warming oil and gas leaks are only part of that.

Here are some animations from 2017 with a similar mission object.

There is also this Map from 2016 by Nasa titled "Mapping Methane Emissions from Fossil Fuel Exploitation":

Here is some real data from Sential 5P an ESA satellite:

Satellite to ‘name and shame’ worst oil and gas methane polluters

That's fascinating! Looks like there are some seriously leaky pipelines in Russia and Algeria. They need to get on that.

I wonder why there is a large emission source along what looks like the northern Appalachians? I wasn't expecting that.
