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.

"President Joe Biden’s administration on Wednesday finalized approval of $1.1 billion to help keep California’s last operating nuclear power plant running. "

Because renewable energy sources are too expensive?

this on its own, without government subsidies. When will the industry find some way to insure itself without the US government’s help? Oh, and when will become cheaper than renewables?

If you want to talk about subsidies, let's talk about how renewables (and even fossil fuels) get MORE subsidies than nuclear energy. Tell us, why is it okay for renewables to get so much subsidies but it's wrong when nuclear gets a fraction of that? Oh and by the way, nuclear doesn't need subsidies to compete with renewables. Wanna know how I know? Because every nuclear plant that was shutdown in the US was replaced by fossil gas, NOT renewables. Fossil fuels get the biggest subsidy which is not having to pay the health consequences of pollution and the climate consequences. But sure, let's waste time about renewables this and nuclear that while fossil fuel keep fucking us up the ass instead of just using renewables and nuclear where each make sense to decarbonize. I don't care how many good intentions you might have, your narrative holds back the energy transition, it doesn't help it in the least bit, especially when we are talking about nuclear plants that are ALREADY BUILT and operating. What do you want? have diablo canyon replaced with more fossil gas just like indian point and san onofre? Because that's what happened and that's what is going to happen again. https://www.eia.gov/analysis/requests/subsidy/pdf/subsidy.pdf

why is it okay for renewables to get so much subsidies

Renewables are a nascent technology and promise a future that doesn't leave a legacy of radioactive waste. Nor are nuclear power plants ripe targets for terrorist attacks. With the help of public investment, the cost of renewables has decreased significantly.

In contrast, after decades of government support, the cost of nuclear power has not decreased.

Save your time. Your support for nuclear is unfortunately preceded by decades of lies by other nuclear supporters.
