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.

Is there a list of carbon sequestration projects? (mander.xyz)

There seems to be a huge number of miscellaneous projects for a specific type of environmental restoration or some other activity that is specifically aimed at carbon sequestration. For example, seagrass restoration alone has a plethora(1,2,3). Is there a decent list of these projects? I found this cool list of CCS projects(4), but that’s different.

If such a list exists, I have another question: Is there an objective way to compare their effectiveness?

There are a few reports out that group them by type.

National academy of science and engineering has one on ocean carbon: https://nap.nationalacademies.org/catalog/26278/a-research-strategy-for-ocean-based-carbon-dioxide-removal-and-sequestration

There's also a state of carbon report from last year: https://www.stateofcdr.org/

I'd suggest Carbon Brief as a good source covering some of them: carbonbrief.org

Finally the EU had a call out last year through the Horizon Europe funding program for research groups to create a framework for carbon removal. I believe they funded 2 or 3 different projects, one of which was focused on ocean-based projects. I can't find a link now, but they were €7mil+, 3-5 year projects, designed to comprehensively assess and compare all cdr options. They should have all launched this summer.

Thanks! There’s so much activity in this space and it’s hard to track it all.
