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.

Analysis of six extreme heatwaves found that when temperature and humidity were accounted for, all were potentially deadly for older people

Anything that doesn't kill you brings you closer to death in some way if it is hurtful.

Heatwaves push EVERYBODY closer to the edge and for many elderly and people with health issues the edge was already right there.

I don't care if a city can claim technically zero heat deaths in the immediate aftermath of a heatwave, people die indirectly from the pure body stress of it excaberating other pre-existing issues and the impact doesn't disappear the next day.

Uhhh exercise can be hurtful (muscle soreness) and I'm sure we can find other examples

Not that I disagree with the rest of your post. I love a good sauna, but the joy of it is that it ends when I get out (and maybe jump into a pile of snow). A heat wave is just... Taxing
