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.

Those ACEEE numbers are predicated on placing an economic cost on pollution. If you assign a larger price to the pollution, even the PHEV's fall right off the chart. The E in their name stands for "Economy". They're focus is framing clean as a function of the economy. In their model, you can kill a bunch more people and the price of pollution only goes up a little. They even say they've left that number constant since 1998. If you value pollution in a logarithmic scale that gets way worse as time goes on, it becomes obvious that the only acceptable vehicles are the ones that have negative pollution costs. Since we dont have vehicles that can remove pollution from the air, getting one that gets as close to zero is the best bet. Right now, EV's get the closest to zero.
