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.

This is the first time I've ever read of China or Russia using "vessels with onboard nuclear power plants to source energy through these periods - and then move on to help somewhere else."

I searched and cannot find any source to back this claim, do you have one?

Because the only vessels I know of with onboard nuclear reactors are naval aircraft carriers and submarines, and neither of those ship classes are designed to deliver power to shore.

Sure, here's a Wikipedia article:

Here's IAEA:

Aside from that, nuclear power is used in some of the icebreakers since the Soviet era:

Also, I was under the impression China has such ships deployed, while they are actually being built. Russia has an operational one.

Thanks for the links. So there is only one Russian floating nuclear power plant and it has a permanent location in Chukotka. This isn't much like what you described to be honest.

It's a relatively new technology, and such is its proposed use.

The Russian plant is stationed there for the time being, yes, but it could be moved elsewhere, which is the beauty of it. It's just that Chukotka relies on it for now.
