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.

I'm of the opinion that a technology should be evaluated on it's own merits, otherwise people start to point out that the field of modern engineering as a whole is the product of the military industrial complex and it gets all reddit-comment-thread-y. I'm not about to argue that there's no astroturfing or outright propaganda in the energy industry (because I don't like looking like a fool or losing arguments because I'm clearly wrong...) though. I wholly agree that it's a hugely manipulated issue, and the mountains of evidence supporting that idea are so large that they threaten to bury you and I and the rest of this comment thread in an avalanche of carefully documented conspiracy and related rat bastardry.

However, I do take issue with painting all proponents of a particular thing as being some kind of fake 'smoke screen'. While I'm sure some percentage of commenters are serving any number of nefarious agendas, they can take their attempt to de-legitimize an entire opposing perspective by painting them all as "shills" and kindly fuck right off. That's trump-supporter shit, and furthers absolutely nothing except to divide voters on an incredibly important topic. That style of wedge-driving is the kind of thing you find in The Foundations of Geopolitics and is what the 'smokescreen' people actually do use to drive potential allies to infighting instead of coordinating an effective campaign for energy reform.

(Not that I think the above poster actually is some nefarious shill, but it's a somewhat amusing juxtaposition)
