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.

Decades after the US buried nuclear waste abroad, climate change could unearth it | melting ice sheets and rising seas could disturb waste from U.S. nuclear projects in Greenland and the Marshall Isla (grist.org)

It’s my understanding most “nuclear waste” is “stuff that has some residual radiation from being inside the radioactive area of a nuclear power plant” like machinery and general trash. In addition, radioactive water can be cleaned up enough to reuse in the steam cycle, and then you just have to get rid of the fairly radioactive resin once it’s spent.

And before someone asks, no, the water some plants have coming out of their cooling towers is not that radioactive water, it’s a separate loop of water that is used to cool the primary loop.
