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.

"Nearly three in four of us will face extreme weather changes within the next two decades, a new study predicts.

"In the best case, we calculate that rapid changes will affect 1.5 billion people," says physicist Bjørn Samset from the Center for International Climate Research (CICERO) in Norway.

This lower estimate would only be reached by dramatically reducing greenhouse gas emissions – something that is yet to occur.

Otherwise, CICERO climate scientist Carley Iles and colleagues' modeling finds that if we continue on our current course, these dangerous changes will hit 70 percent of Earth's human population.

Their modeling also suggests that much of what's to come is already locked in.

"The only way to deal with this is to prepare for a situation with a much higher likelihood of unprecedented extreme events, already in the next one to two decades," explains Samset.

We've already lived through examples of these extremes..."

Well let’s wait and see! I bet most will agree it will feel extreme.
