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.

If this is true, I have questions about Ecosia tree planting efforts.

Ecosia supports over 20 tree-planting projects in 15 different countries; Peru, Brazil, Madagascar, Nicaragua, Haiti, Colombia, Spain, Morocco, Senegal, Burkina Faso, Ghana, Ethiopia, Uganda, Kenya, Tanzania and Indonesia.

If the map from the article is true, that would mean that planting trees in Morocco, Senegal, Kenya and parts of Ethiopia are actually counter productive and will increase climate than reducing it.

This article talks about albedo but ignores changes in the water cycle. I wouldn't take its results at face value.
