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.

It's worth noting that he also fired many of the staff who know how to ensure that they're actually safe, as well as the staff who would approve financing.

The cost goes up entirely due to red tape and lobbying from fossil fuel organizations. Remove the boot that is nuclear fear induced largely by oil companies and actually commit to nuclear R&D and the cost will drop. And even the recent breakthroughs China made with Thorium made are genuine, even more so. And unlike every other power generation industry, nuclear operators are mandated by law to put aside funding to handle waste. Tell me which solar industry members are doing anything about PFAS generated in their production or wind turbine operators who give a damn about how many landfills they are flooding with expired turbine blades.
