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.

In southern Italy, in Sicily, it's just 44 °C (111°F). Up north in Milan, there was a tornado and now massive ice floes are going through the city.

I found myself in a tent in the mountains around Bergamo last week. After continuous lightning for several hours, around 4:30 at night our (pretty safe looking, not at the bottom of the terrain) tent spot turned into a river with 15 cm of water and hail running straight through the tent. The tent of course also filled with water, and we had to evacuate in the middle of the night.

Thankfully there was a rifugio/mountain cabin just a bit more than an hour from there that we had passed the day before, that we could get back to and seek shelter in. In the morning another round of the storm came along, blowing away huge outdoor tables along with the fence of the rifugio. Some people were arriving in the beginning of the storm as the forecast had been just fine and they had set out in the morning.

In the end, looking at the weather in the North now, I'm just happy it wasn't even worse.
