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.

Hurricanes are not getting more frequent or violent because of climate change though. They are likely to become more rare with increasing temperature in the northern hemisphere because of even temperatures in the weather systems.

Lex Friedman ep 339 does a good job explaining the difference between more and severe weather and people settling down in huge numbers in already exposed areas.

We had a huge rainfall in Norway last year submerging a lot of properties. People said this was unprecedented and because of climate change. Only issue is that we have historical data on earlier floods, and people had settled down below the markings of earlier floods more than 100 years ago. The issue is not climate change, but regulating properties on a patch of land you know with 100% certainty will get flooded again.

You know how matter changes from solid to liquid to gas at certain points? I believe there are phase changes in ecology and environmental habitability and sometimes things seem fine and suddenly they aren't.

At the risk of sounding prejudiced and offensive, the norse are a very smart and sexy group of people, so perhaps I am wrong in not accepting your illogical and sexy perspective?

I just think 1 variable of change is not the correct barometer of "how close are we to the ecological abyss?"
