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.

Honestly plug in hybrids are the worst of both worlds.

There was a study recently from Europe that found the vast majority of people with plug in hybrids hardly every plugged them in, and drove them like normal cars. That defeats the entire point of a plug in hybrid, and now you are carrying a heavy battery everywhere that you are not fully using. Which makes the car less efficient than a normal hybrid!

Yeah, it depends on the user.

I had an alcoholic neighbor with learning disabilities who had a PHEV minivan purchased for them, and they only kept the battery charged for the first few months of ownership. After that, they seemed to lose interest in plugging it in when they got home.

On the other hand, a friend of the family owns a PHEV sedan they keep charged religiously, and they need to buy fuel stabilizer because they almost never use any gas.

An alcoholic neighbour and someone purchased a car for them?
