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.

Good, and I use one. It's mind boggling that anyone wouldn't use one? It uses so little energy that I don't even notice. My stupid always-on smart TV uses more power...

I wouldn't say I don't notice as it's most of my energy use. Monthly in summer we use 150-200kWh, in winter its 550-650. Heat pump does heating and hot water so the shower uses it too.

True, my old place couldn't setup the pump for water heating also, plus my place is smaller and in an area that doesn't get too hot or cold. It's mostly a very inexpensive AC for me.

The water heater is on the todo list but it's a but tough to afford everything at once.
