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.

Frankly a highly speculative set of conclusions. Despite the green deal forbidding converting woodland to crops, the author assumes the opposite. Then they basically ignore the organic requirement. The idea that EU will wholesale move their food production (likely the strictest in the world) to Africa is so outlandish as to not be taken seriously.

An analysis of the policy documents outlining the practical measures of the Green Deal shows that it will decrease carbon emissions in Europe, but also increase carbon emissions outside the EU. This increase is more than double the amount of carbon emissions saved by the Green Deal.

Their conclusion is that the Green Deal in its current form will lead to an increase of 244.8% in emissions in countries outside the EU compared to the Green Deal's carbon reduction goal in the land, land use change, and forestry sector within EU borders.

Yes the idea is that other countries will follow suit, but who's gonna ask countries that are still developing to pay extra 25% cost of something that's sustainable.

This is only about land, land use and forestry. So the request is pretty much not to cut down forests. That is asked all the time, for very good reasons.

3billion trees sounds like a lot, but the area it takes to plant those trees is less the 1/1000 of the area of the EU. I highly doubt, that this would lead to a measurable decline in EU farm land and especially high quality farm land.
