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.

40% of global ship traffic is simply moving fossil fuels around! Renewables make much of this traffic obsolete (slrpnk.net)

Mandating solar PV in all building codes nationwide, and incentivizing onshoring of all of the processes that go into manufacturing solar PV panels (including using trade protectionism practices such as tariffs AFTER WE ALREADY HAVE PROCESSING AND MANUFACTURING CAPABILITIES IN THE USA) will do wonders for helping average people transition away from fossil fuel Internal Combustion Engine (ICE) cars to EVs.

Many people who cry foul about EVs and renewables adding too much load to a grid that is too old and just can't handle it forget the main counter to disarm their arguments: colocating generation with utilization.

Having solar PV (and other renewable) generation closest to where that power wants to be used is the best for the grid infrastructure (maybe not the grid investors) because it reduces residential/commercial load while maintaining the needs of the original giga users of the grid: Industry.

There are solutions to SO many of today's problems. We just have politicians that are bought and sold by billionaires and their corporations who won't do the public's bidding. Voting progressive politicians in, and preferably ones who vocally claim they're Democratic Socialist or similar, is the strongest way we push back against Big Oil, Big Coal, Big Tech, and all the other mega industries.
