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.

analysis for Nebraska that would apply for Estonia or Canada as well with only a few parameters changed. Free 24/7 baseload solar electricity if Hydrogen can be sold for $2/kg (equivalent to 25c/liter gasoline in range). https://lemmy.ca/post/59615631
Nebraska actually gets like 5-10x the useable solar power in the winter months compared to Estonia. We essentially don't see the sun from about nov to mid feb.
All of the H2 would have to be generated between spring and fall and stored for winter. Selling it and then buying it on-demand in the winter wouldn't work because fuels shoot up in price come winter. Cost of my wood briquettes tripled between July last year and February this year for an example, usually it at least doubles... And once I've seen them quadruple. Luckily it's a single house worth of solid fuel, it's easy to stockpile. I'm wondering how a couple of terawatthours worth of H2 storage would work.
To be clear, I'm not at all against solar or renewables in general, I just don't see any energy storage solutions that would work for my country if we tried to fix our shit as a nation. On an individual level it's doable, but payoff period is so long that it makes more sense to just keep using grid power.
analysis I replied with didn't require a separate heating solution, though heating 1000l or 2 of hot water in fall would be a great strategy for every home heating system. The reason H2 electrolysis (just sell it instead of using it for heat in winter, though that is also a solution) works even for "your solar shithole country" is the massive summer daylight. No H2 produced outside of the good months.
