The corals are casualties of surging global temperatures which have smashed historical records in the past year — caused mainly by fossil fuels driving up carbon emissions and accelerated by the El Niño weather pattern, which heats ocean temperatures in this part of the world.

Question one: way over my pay grade. I’m closer to a CCNA than a software developer.

Question two: flipping breakers on and off is really the best way to figure out how your house is wired. It is MUCH easier if you have someone who can help you. Lights will be easy and obvious. Things like wall receps will take some time. Especially if you have an older house where past owners have made modifications. There are circuit tracers for this but they don’t work that well. You’re better off using a voltage tester or outlet tester that will beep when it has power. Any breaker that is a double or two pole breaker will have a specific purpose. If it’s 40 amps there’s a good chance it’s an electric oven or drier, if it’s 60 amps it almost certainly your HVAC.

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.
