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.

Yeah and what do you think that happens to the carbon when said tree dies?

Trees are a great way to capture carbon once, that's it. If you build a Forrest somewhere, that forest will take x tonnes of carbon and that's it. 30 years later when the first trees there start dying , that carbonnwill go back again and new trees that replace it will take it again, etc.

You will need to plant billions of trees to make even a dent in global warming

Indeed, we will need to plant billions of trees, and losing any more of them that we already have than we absolutely have to isn't going to help anything. Is this really news to you?

Meanwhile, you can cut down trees for materials and let more of them grow. Don't have to level forests to do it either.

Oh, and again, larger trees sequester more carbon on less land versus smaller ones -it's more efficient if we can keep them around.

Its truly bizarre how anti-tree you're being for supposedly also being worried for the world's forests. A substantial portion of the remaining forests are home to evergreens.
