Interesting article but it bizarrely completely misses what is likely to be by far the biggest source of climate change-related death: famine. Humans can shelter from the heat and we can displace our air pollution (thanks EVs) but our crops are still stuck in the field and you can pretty accurately predict yield losses from increased temperatures and increased/decreased rainfall.

This is bad enough in developed nations, where food prices will increase, choice will decrease, and general inequality will worsen. But things will become way worse in developing nations. These mostly practice inefficient, environmentally-damaging subsistence farming and when they start to produce even LESS food, they will just become failed states and hotbeds of civil war. This will bring about much more death and migration, most of it only visible to your average westerner on their TV screen as talk points for your local left/right-wing politicians.

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.
