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.

The report itself is here:

Fossil fuel emissions have rapidly worsened European heatwaves in just a few decades

Just weeks after a severe heatwave that broke all-time May records, Europe is experiencing another major heatwave that is breaking June and annual records. This is particularly remarkable given that June is not historically the hottest month in Western Europe. Across France, Germany, Italy, Spain, and southern England, temperatures are reaching 5–12°C above seasonal averages, driven by a persistent high-pressure system. This pattern has transported hot air from North Africa into the region while also bringing clear skies and strong sunshine, which have further intensified the heat.

same problem here, with the cats and all, and it's the kind of things you don't want/can't do when it's so hot

It was so cool this morning outside compared to my living room which only cooled to 29c overnight. Might be time to look at the window net idea. Suspect that the living room would have cooled down a fair bit more if I had been able to open the windows more at night.

Other rooms are more variable as they get direct sun in mornings or evenings. Normally the living room is coolest but now after days of heat it's warmed up quite a bit. Looks like the worst of the heat is over now though so it should start cooling off. Might open the doors when I get home and contain the cat in the bedroom for a bit.
