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.

While the Republican majority in the House means that this kind of thing won't pass this session, it gives a sense of what Democrats might try to pass if they win enough seats.

The problem is that people are conditioned to blame the president for the current cost of gas, and that gas should always cost the same. If not, then inflation is too high, never mind that keeping the cost the same means the real cost is falling. Or that right now gas costs two cents lower than it did in 2013 pre inflation.

Amaricans would absolutely blame the current government for gas going from $3.52 a gallon to the sill subsidized to an extent EU average $7.31 a gallon. Throw in the more realistic costs of actually cleaning up said co2 with direct air carbon capture at a $100 a ton and you get $8.20 a gallon, which is actually nowhere remotely near as bad as I expected it to be, though that would require someone to actually do carbon capture at scale. Electricity of course beats the pants off of all of the above at an US average cost of about $1.90 per gallon equivalent.

You also have the inflationary effects of the US being very dependent on trucks for most goods transport, due in no small part to rail companies entering a state of ‘managed decline’ and looting said infrastructure for scrap at a time where everyone from China and India to Ethiopia and North Korea were electrifying, and thusly being stuck with trains that cost nearly twice as much to run as electric lines run by an industry of managers who think that their customers are going to replace a single train with gravel with several thousand trucks any day now so might as well sell the tracks off.

That being said, a high vehicle registration tax on gas and diesel vehicles combined with an effectively free one on new energy vehicles seems to have demonstrated more of an effect, though admittedly places that have tried that have also tended to have a far less subsidized cost of fuel in the first place so it may only have an potent effect in combination.

Functionally the US also needs an equivalent to or allow import of the French Ami and similar such cheap city cars as well as Canadian style legislation demanding that landlords must install L2 chargers if asked if it wants for cars to still be an option for poor rural people, which unfortunately given the need to cut carbon now and the demonstrated ability of US cities to take a decade and millions of dollars to put in a bus lane it probably does. City dewellers will of course just use bikes if they can get their city to stop wasting money on far more expensive to maintain per person-mile car lanes.

All in all this problem needs a lot of complex legislation to solve, but I sopose the benefit of WAITING THIRTY FUCKING YEARS AFTER IT DECIDED THAT CONTINUED EMMISIONS WERE A CLEAR AND PRESENT DANGER TO THE VERY EXSISTANCE OF THE NATION is that most of the possibilities have already been tried before so you can pick what works and skip what doesn’t.
