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.

Beware of any history that makes the current state of affairs seem inevitable. There are always countervailing forces.

There are dozens of articles if you do a search online, but here is one article from Bloomberg.

Americans have grown up with versions of the “car culture” thesis: This is a nation that simply likes cars, and this preference is the biggest factor in the extent of car domination. Maybe clever marketing and interest group lobbying has something to do with this (the thesis concedes), and maybe the preference is not rational; still, we prefer cars, even in settings that are poorly suited to them, and even to the point of putting up with their high financial, social, environmental, and safety costs. All over America in the 1950s and 1960s, residents, particularly women, organized demonstrations against car traffic.

Anti-car protests were successful in places like New York City and Vancouver, Canada, which is why they are some of the only places in North America without highways cutting through them. San Francisco also had major protests, but highways were forced through anyways.
