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.

They believe that their actions are justified because they believe that they are morally superior. They are self-absolving. That is the hallmark of extremists of all types.

That's why.

Why do you think that about them? Is that based on anything that's actually in reality?

It is obvious that they feel justified in inconveniencing or endangering hundreds or thousands of people at a time by blocking roads and bridges, invading the stage at performances, etc. Any one of those people could be rushing home to meet their children, or to a hospital to see a dying parent, or facing the loss of their job if they're late. An inattentive HGV driver could plow into the back of stopped traffic and kill people. But, it's totally ok because their motives are pure. That's self-absolution. That is the hallmark of an extremist.
