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.

As countries scramble to secure oil, gas and fertilizer, China’s bets on clean energy and coal are cushioning its dependence on oil and gas imports.

The coal part isn't so great though.

The Trump administration is reviewing proposals to break up one of the world’s leading climate and weather laboratories, transfer its work to universities and private companies, take away its aircraft, and sell its property in Boulder, Colo.

The lab in question is NCAR, the National Center for Atmospheric Research.

The key thing here is that they're good for two kinds of things:

  • LLMs can do things like write SQL queries or visiualization software
  • ML can be used to do a better job of approximations in some situations

It's almost like Republicans want oil to be ridiculously expensive and to force us all to buy it.

Cycle lanes, electric cars and other interventions have helped 19 global cities slash levels of pollutants by more than 20%

Notice how the main approach was to avoid burning stuff. That's a key step which both reduces the amount of warming we'll get, and avoids significant local pollution.
