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.

Will America ever stop building more highways? As emissions rise, some environmentalists are turning their attention to widening roads as well as pipelines (wapo.st)

No. “America” won’t. It’s a grift and a jobs program all rolled into one.

Or...we can find a way to not need building highways.

Just because something has been happening doesn't make it an inevitability

probably just as soon as city sized arcologies are built and everyone moves into them

If we have wider roads, we can increase the number of electric vehicles which is good for the climate.

With wide enough roads we could even reduce congestion. The future is ours!
