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.

Continuing to punish individuals for basic living needs isn't going to do anything more than continue to make life more unaffordable

In an ideal world, yes, we'd keep the carbon tax cranked. But fuck that. People with oil heaters would get off them if they could. If they're still on oil, there's probably a reason.

The current subsidies of heat pumps look like they're structured as loans. And they're complicated. Don't do that. Just install the damn heat pump for free, and call it a day.

I think they should get an exemption as it is literally keeping them alive.

I think a better solution would be to heavily subsidize heat pumps, resistance furnaces, and electric space heaters and make them more cost effective to use. People will switch to save money. Of course the cost of electricity has to be significantly cheaper than the oil.

Electric furnaces are very common in Canada, though I don't think quite as common as oil/LNG.
