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.

Electrical engineer degree but I'm doing software now.

I'm not against EVs. I'm against y'all bad-mouthing PHEVs and Hybrids when they still constitute the top of the green lists with our current level of technology.

I recognize that better batteries are coming next year and soon Silicon or Sodium batteries will be even better after that. But tomorrow is not today. People making decisions need to make decisions based on today's level of technology.

If all the cars available today, the Prius Prime does the best job. And anyone who doesn't have enough money for Prius or a Leaf or other EV can go buy a Honda Accord Hybrid or Corolla Hybrid and feel good that they still got a top15 vehicle on the green lists.
