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.

I used to work for a property insurance company about 10 years ago and by that time, no one on the industry was a climate skeptic.

Here's something they did about earthquakes we might start seeing in areas where climate change hits hardest:

This is on the west coast of Canada, and this company jacked up premium prices in areas they thought would be hardest hit by the anticipated mega-earthquake that may happen any time between now and a hundred years or so. They were hoping to dump those customers except it turns out all the other companies had the same idea. This started a gouging war between them, believing the only solution is higher and higher premiums. So many people just ended up paying more with no option, or without realizing they had one. There was only one major carrier that didn't do this and if your broker didn't sell their policies, you just had no option but to pay way more.
