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.

Absolutely.

Survival of the fittest means the ones most suited for their environment survive enough to pass on their genes. When the environment changes (a new predator moves in, humans tear down your habitat to build condos, the ocean heats up so you don't have enough food for everyone, etc) only the members of your species that can handle the new condition will survive to pass down their genes.

Maybe as oceans warm, the remaining crabs will evolve to survive their changing environment better. Or maybe they will go extinct because they can no longer compete with species that are better suited for the warmer oceans. Either way survival of the fittest still applies 100% whether the cause is climate change or some other evolutionary pressure.

Does that clear up why it makes no sense to say that this somehow proves Darwin wrong?
