one of the simplest nudges would be to make roofs white. Messing with the atmosphere is bound to have consequences that exceed the expected or realized benefit.

I recently read something about the emission reduction during pandemic lockdowns resulting in cleaner air which in turn caused the planet to heat up even faster. If we manage to bring back air pollution far enough, the planet’s temp will still rise a few degrees because of that. Which in turn may trigger more chain reactions. So many butterflies, so many effects, so maybe not a bad idea to research the risks and benefits. I agree it sounds like a bad idea but bad ideas can lead to useful insights too.
Cooling down the planet, just dig it. I’m brainwashed with that line from the hundreds of times I heard it. Apparently digging holes in deserts works. Same goes for removing terrace tiles / concrete slabs in cities. Better drainage, less flooding, more vegetation, cooler planet.
Bunds are doing their job: regreening Kenya and reducing flooding | Dutch Water Sector
Together with Maasai communities, Justdiggit dug 78,400 semi-circular bunds to catch rainwater and brought back vegetation to the once degraded areas in Kuku, Kenya. Heavy rainfall in the past months caused serious flooding in low parts of the country, but also boosted the country’s regreening...

I’d like to see that done in a real desert, not someplace with trees.

Aside from all the negative effects all over the world I can’t help enjoying the positive effects like more sunny hours, local beaches feeling like tropical destinations, rivers low and slow enough I can swim across them. At least till things are so clearly messed up. Like roses flowering last winter.
This week it’s high 60s in NL, normally below 60 this time of year. I can smell winter in the air, but that air is still warm. For weeks I put on a jacket and go outside to find out I don’t need it yet. It’s getting weird. Partial solar eclypse helped set the surreal mood. Projection is this will become normal october weather, with higher extremes.

My falls and winters have been warmer here in NW Florida too. But last year we had crazy early frosts, (17 before the New Year) and it did the same last week. We have already had four days with frost when the usual first frost is in December or January.

I think wind might be a better option for northern Europe, but whatever works, however, to make it work we need energy storage, batteries and such, for the grid and EVs.
If a republican congress kills climate change policy for bribes and a moronic base, then America will simply get left behind and will end up buying technology developed abroad and bought from abroad. Eventually economic sanctions will be applied for noncompliance, even to America, which currently controls around 20% of the global economy. EVs will come, even with a hostile government, unless they force the domestic manufactures to produce ICE vehicles. All the automakers have seen the writing on the wall and are betting the farm on electric.
Maga republicans burn books and do all kinds of stupid and evil shit, this would be just another. There are bribes to be gotten from the oil industry and suckers to brainwash in hurricane ally, pay no mind and stick yer head in the sand until the water covers yer ass. Florida don't believe in no stink'en climate change fake news. BTW you know where I can get house insurance for my mortgage, for some reason nobody wants to sell me any, Foxnews says it's Biden's fault and part of a conspiracy!

New solar capacity 10 times cheaper than gas, says Rystad
Operating gas-fired power plants would be 10 times more expensive in the long-term than building new solar capacity in Europe, according to research from intelligence company Rystad. Their study uses the levelized cost of energy (LCOE) for gas and coal-fired power generation at different price...

Dark Brandon strikes again! It's socialism I tell ya! 
Dark Brandon just signed an international climate treaty.... then Mitch McConnell voted for it.
Most of you good readers who are old enough probably remember all the talk about the Ozone layer from the 70’s and 80’s. In fact, climate deniers often use that as an example of how “the science was wrong” because “look, the Ozone layer is fine.” Of...

How super-hot rocks miles under the earth's surface could provide limitless clean energy
Superhot rock geothermal energy can be generated from dry rock that's at least 752 degrees Fahrenheit, which lies at depths between two and 12 miles.

For those who want to find out more about gyrotrons and drilling deep wells with them economically this guy from MIT started Quaise Energy to exploit the technology mentioned in the article above. They use 28 GHz waves that pass right through the plasma generated while compressed air blasts it away and keeps the drill head cool, the borehole is glass lined by melted rock.

Into the Bedrock by Full Bore Millimeter-Waves
Drilling into deep crystalline basement rock is a bottleneck technology to accessing vast resources of geothermal energy and to a possible solution to the nuclear waste storage problem. Commercially available high power millimeter-wave sources developed for fusion energy research could be a drilling game changer by enabling full bore directed energy penetration. This wavelength range propagates well through optically obscure paths and is well absorbed by rock melt, it can be efficiently guided long distances, and sources come in megawatt average power size units that are over 50% efficient. The electricity costs to melt or vaporize through a hard rock formation could be less than 1/10 of current costs of a deep mechanical drilled hole in softer rock. Melt/vaporization experiments of granite and basalt with a 10 mm wave beam have established its feasibility in the laboratory at MIT.

Another potential competitor for Niron magnets though they are much further along in development and a general move away from rare earths, both in magnets and batteries.
