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 above and beyond what overfishing does. Per the article

“Historically, overfishing has been the main driver of biomass declines in many of the world’s fisheries [and] according to the FAO [UN Food and Agriculture Organization] the proportion of overfished stocks globally continues to rise,” said Ortuño Crespo, who was not involved in the study. “The current challenge is that this overfishing crisis is being further exacerbated by ocean warming and deoxygenation.”

Welp, we're cooked. My kids and their kids will be cooked. Great. Not what I had in mind when I was growing up and imagining what I'd be like as a dad. My two young ones will have a rough time.
