NIMBY never gets out of fashion, does it?
I expect that a fair number of people are considering doing solar roofs as they have to replace them. My mom is considering it, and we've been considering it here as well; and since Sally did damage our roof, but in a sneaky manner, hopefully that will be soon.How it started (Bell Labs, 1954):
How it's going:
For reference, the world's total energy consumption of all kinds is around 18,000 GW. 200GW of new solar translates to 50GW of average output, or 0.28% of world energy supply. We need a couple more doublings of the installation rate, which might take 10-20 years.
At some point in the future, what is left of humankind will view the world like this. with habitable land falling inside the Arctic Circle. The ice will be gone, and the Arctic Ocean will be as balmy as the old Mediterranean Sea. Residents of these upper latitudes will fight off the hordes of Southern Mutant Barbarians who threaten to overrun them when the harvests are good.
It's not like we don't already know what the obvious solutions are, it's just a collective unwillingness to make the changes fast enough.It is possible you are right Beebo, but there is a possibility as well that students in 2121 smile when they research old newspapers and Internet archives and discuss how on earth it was possible that the people in 2021 did not stumble over the obvious solutions right before their noses.
Presumably, given enough time, the world's temperatures will revert to a mean average, simply by the laws of mathematics.
If the thermohaline circulation is disrupted then no more Gulf Stream and Europe gets chillier among other effects. And some of the other effects are more serious in the long term. These ocean currents take cold, saline, oxygenated water from the poles along the ocean floor and upwell at lower latitudes entraining nutrients from the ocean floor. The Gulf Stream (and other poleward moving warm surface currents) are the return flow.
Only in some locations, and not on a global level.
I knew it was a symptom, and no, its not a good thing - the last study I'd seen on it suggested it was in fact a very bad thing, because it would cause a lashback of freezing near the poles, as well as an overheating in southern climes because they didn't get the cooler water because they system would be broken. But I guess that was 15 or so years ago.Only in some locations, and not on a global level.
The thermohaline circulation moves warm waters from the equator up to the northern latitudes, buffering places like the British Isles from the cold temperatures that they would otherwise experience. So if infusions of fresh water disrupt the circulation pattern, that warmth is no longer dispersed along those coastal areas in the north and they revert to the same cold weather the rest of us have to deal with every winter.
This doesn't CREATE cold weather, so it's not much help against climate change. Instead, it's one of the symptoms of accelerating climate change.
