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.

This is about species as a whole and their physical characteristics. All humans are the same species and religion is a social construct, so that does not apply. Eugenics =/= Darwinism and it is intellectually dishonest to equate the two.

Also, there is nothing about winners and losers in Darwinism. It is simply an observation about the natural world. The world is always changing and is never static. Those who can handle the change will make babies and pass on whatever quality they have that makes them suited for their current environment. In the future, that quality may or may not be selected for. Or maybe you have a quality that is not beneficial for your environment, but is not harmful for your survival either, thus it may continue to be passed down (e.g. my shitty eyesight that was passed down, but with correction doesn't impact my survival).
