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.

Joe Biden just did the rarest thing in US politics: he stood up to the oil industry; The Biden administration suspended new permits for natural gas terminals. Can we see more of this kind of backbone? (www.theguardian.com)

So in Montreal everything runs off of electric heat and it gets super cold out and it's pretty warm indoors with the heating running on super low. Maybe you guys just don't know how to use electric heating properly.

Your comment made me curious because I know I have read about heat pumps not operating well in cold temperatures. So I looked it up a little, apparently there are cold climate heat pumps and they aren't installed in most places in the US. Where I live, heat pumps work okay a lot of the year, but we do get cold snaps where they just can't keep up. Apparently you actually have a better heat pump it would seem.

Yupp, they work fine in Norway and it gets cold enough here.
Had spells of -30 °C this winter.

You'd be hard pressed finding a any home here heated with gas. Its all electric or wood fired.

Funnily enough, most of our heating is done using baseboard heaters, or resistance heating. Newer constructions have heat pump/air conditioning combos but I don't know exactly how widespread they are, my parents have one and it's definitely more efficient than the baseboard heaters, but not by a huge margin.

I don't know if you know his channel, but Technology Connections did a couple of videos on heat pumps that were pretty eye opening, I imagine as much for Americans who have been hit hard by gas and oil lobbying, as for me as a Canadian who hasn't ever really seen anything other than electric heating.
