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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Heat pumps don't really work in extreme cold. My office has only electric heat and it runs constantly when it's really cold, never getting up to a comfortable temp. My home stays warm with gas heat and the furnace runs far less.
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.
Yeah older heat pumps can't stand >5°C temps (at least my 20yo one), newer ones seems to be way better even in cold temp.
