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.

A realistic understanding of their costs and risks is critical.

What are SMRs?

  1. SMRs are not more economical than large reactors.

  2. SMRs are not generally safer or more secure than large light-water reactors.

  3. SMRs will not reduce the problem of what to do with radioactive waste.

  4. SMRs cannot be counted on to provide reliable and resilient off-the-grid power for facilities, such as data centers, bitcoin mining, hydrogen or petrochemical production.

  5. SMRs do not use fuel more efficiently than large reactors.

See the Australian conservative opposition (Liberal and National parties), for example. They are bought and paid for by the fossil fuel industry, have no actual plan to roll out nuclear, but are using it as a delay tactic. See also how conservative parties are attacking renewables but not directly talking about coal (for the most part) because they know that the general public won't accept it anymore. Conveniently, attacking renewables and talking up nuclear is an easy way to keep coal around for a little longer.

Your points are more historical, I'm talking more about the last few years or so, the period where most conservatives now won't admit to being climate change deniers, but incidentally have positions that worsen climate change.

It's more your characterization that only conservatives are advocating for nuclear (and by extension that nuclear advocacy is only to serve the interests of fossil fuel companies) that I'm taking issue with, since it's overly reductive, regressive, an opinion which can be trivially shown to be incorrect and is a direct insult to me, personally. You're coming across like an asshole that spouts blatant conspiracy theories when I seriously doubt you'd give that impression IRL.
