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.

There's no difference between two 20A 120V circuit and one 40A 240V circuit. Two 12/2 vs one 10/3. Two breaker slots vs 1. Each conductor in the 240V circuit is the same volts as the hot of the 120V circuit. All fire risks and such are essentially identical.

You should not do home repair beyond your comfort zone, especially electrical. That said, there's nothing particularly spooky going on here.

Wiring up 240V circuits with 60A fuses was literally something many British and Irish kids did before their teens before the 90s. You had to wire plugs for every new item you bought as they were sold separately. Plugs has 13A fuses, so current was more limited... Unless you wired it wrong...
