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.

Yes, there was global warming in prehistoric times. But nothing in millions of years compares with what we see today (www.latimes.com)

That's the point I was trying to imply with my sarcastic first comment.

Climate change deniers always like to point out ancient prehistoric changes that occurred on earth thousands or even millions of years ago ... and they are right.

What they seldom understand is that the earth can weather these unbelievable changes but life, especially human life can not.

I never worry about the planet. It will be around for about another billion years in one form or another. It's always a question of whether or not any living thing will survive on it's surface.

I was being stupid with my first comment and I don't mind being stoned for it .... I just wanted to point out that climate change is not a problem for the planet ... it's a problem for the survival of all human life.

Ah, I didn't catch the sarcasm! Poe's law and all that
