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.

Fish are shrinking around the world. Here’s why scientists are worried. | Figuring out the reason why has big implications, with billions of people depending on seafood for protein. (wapo.st)

The pair restarted their work in Massachusetts with about 400 brook trout reared for up to eight months in tanks. The scientists kept some of the fish in waters set at 59 degrees Fahrenheit while others at 68 degrees Fahrenheit. All were fed the same diet.

By the end of the experiment, the difference was stark. The trout raised in warmer waters were on average less than half the size as the other fish.

Sigh. Ignorance is bliss, isn’t it? Not everybody can afford high-priced foods or have access to the same foods you do.

Doesn't matter -- fishing, as an industry, is entirely unsustainable and we're both dredging the bottom of the ocean destroying ecosystems and polluting the waterways with hundreds of tons of plastic refuse every year.

Whos the ignorant one? The one that thinks the vast majority of fishing isn't abhorrent industrial practices. The one repeating known propaganda from the fishing industry.

There is a difference between a negligent fishing industry, plastic pollution, and people who need fish for their diet because they cannot afford otherwise. I’m speaking to the last one, which has nothing to do with the other two; one of which has very little to do with the other. Your argument is all over the place.

Yeah and if there are places that rely on fish to survive then it's kinda evil of anyone in an affluent nation to est fish from our big trawlers depleting their reserves.

Stop eating fish, it's thy only moral option.
