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.

Guess it's back to electrify everything then.
Induction and heatpumps are the only answer.
For home heating and cooking, they're definitely a good route.
Ordinary coil stoves are fine to cook on too (I did for decades) but don't meet the need for upper-class signalling in the way that induction does.
It's not their effectiveness that's in question, just their efficiency.
Obviously the conversion of electricity > heat is always the same (100%) but induction is better at getting more of that heat into the food rather than the surroundings.
I wonder if geothermal is something they can do there.
It's common in the Nordics and is usually the cheapest way to heat homes.
Last winter electricity was so expensive that district heating won.
But geothermal has otherwise been cheapest.
Most of the time when people suggest heat pumps they mean ground source ones. District cycle heat pumps would be the best solution from a cost and efficiency perspective, but require common action to install new infrastructure and so are harder to get than building level solutions.
Outside of that, unfortunately geothermal electricity tends to be very location and geology dependent. We absolutely should be taking full advantage of it where we can, but there are unfortunately limits on where is practical.
