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.

36,000 tons a year and how energy is needed to sequester this piddling mount of CO2? Leaving the pre-sequestered stuff on n the ground is definitely cheaper. Bring on the carbon tax.

I shared the article because it is relevant to this community but I personally do not like carbon capture. You don’t need to capture what you don’t create

Thanks for the article. Your thoughts are probably similar to mine in that carbon capture probably is part of the solution but it’s hard to see how the volume of CO2 captured can be ramped up enough to be meaningful. It is certainly meaningless if we don’t stop burning fossil fuels.
