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.

Resistive stoves are slow because heat has to move from the coils, to the air above the coils, to the glass top, to the pan, to the food.

Gas stoves are fast because heat can move from the flame, to the pan, to the food.

Induction cooktops are the fastest because heat gets to move directly from the pan, to the food.

Induction uses magnetic fields to directly impart energy into the metal of your pan. Magnetic fields move energy at the speed of light. That's faster than gas can move heat. Which means your pan warms up quicker.
