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.

If you start a nuclear project today, you'll get it in 20 years. And that's for conventional reactor designs with all their well known flaws. If you spend the same money on renewables and storage, you'll have it all up and running next year. We don't have 20 years. We need solutions now.

Again, what energy storage are you taking about? See my other reply about it. But perhaps a combination of both might be feasible. And you're right, we're late in any case, some countries even stupidly so by closing nuclear power plants for populist reason.

The German nuclear plants were closed because they were obsolete and nobody wanted to take responsibility for running them way past their design life. You can spread the same tired old myth all you want, that doesn't make it any more true.

Nuclear power plants get extended lifetime if there is will.

Also

Three days later then-Chancellor Angela Merkel – a physicist who was previously pro-nuclear – made a speech called it an “inconceivable catastrophe for Japan” and a “turning point” for the world. She announced Germany would accelerate a nuclear phase-out, with older plants shuttered immediately.

More than 30% of Germany’s energy comes from coal, the dirtiest of the fossil fuels – and the government has made controversial decisions to turn to coal to help with energy security. https://edition.cnn.com/2023/04/15/europe/germany-nuclear-phase-out-climate-intl/

Big win ... for the global warming.
