Rainfall is often treated as a gift of geography — a function of latitude, oceans, and atmospheric circulation. A growing body of research suggests that in the tropics, it is also a product of ecosystems. Forests do not merely receive rain. They help generate it, regulate its distribution, and sustain the conditions that allow it […]

    I’ve been mentioning the Amazon aerial rivers for years, and the biotic pump: they also help cool down the climate https://news.mongabay.com/2023/02/forest-modeling-misses-the-water-for-the-carbon-qa-with-antonio-nobre-anastassia-makarieva/

    The entrepreneurs and other settlers destroying the Amazon now will end up [dying] in a large desert.

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.
