Pardon my crudity, but is there a reason to not build a bunch of nuclear power plants + carbon suckers powered by electricity?

Apart from the time it would take, and the total carbon released during the building process, and the fact that it would still not get close to net zero?

If the temperature drop becomes inevitable, I wonder if it'd be worthwhile to just colonize Antarctica to make up for the lost landmass elsewhere. Maybe it's time to have more than scientists living there.

The extreme seasonal summer/winter swings in light levels makes this undesirable, independent of the temperature.

It won't just be worthwhile, it will be necessary. If and when the time comes, that landgrab will be a massive struggle in itself.

I am not a "denier", I can recognize that anthropomorphic activities are changing the climate over time and we're not prepared to deal with that. But this sort of article annoys me because "on record" represents a nanosecond of geologic time. There are mountains, and plant fossils [1] under the ice at Antartica, so at some point in the geologic record there was little to no ice at all! And no humans likely either, wh…

The scientists know this. Paleoclimatology is one big part of climatology. But the outcome is the opposite - you should be more scared, since it shows that climate can change massively. That affects things like agriculture or sea level. What would you assume the sea level was, when those plants were alive? For example, with very quick search: "In general, world oceans were about 100 to 200 metres (330 to 660 feet) hi…

I just went looking for a map to see how different coastlines would look with a 200m sea level rise. It's, unsurprisingly, significant!!

Difficult to build housing. For example, Greenland housing shortage is severe:

>> These staff residences are important for attracting employees, as the waiting time for a municipal rental property in Nuuk is between 10-12 years for a private individual.

“carbon suckers”: perhaps the fact that we don’t even have a popular phrase for the technology, let alone having built anything practical, will answer your question sufficiently. That, and there are a lot of other inputs to that equation such that when I read what you typed, I kind of paraphrase it as, “why don’t we just wave a magic technology wand and make it go away?” :-)

The vast mass of humans who will be displaced by sea level rise will come from hot, humid regions of the world, primarily southeast Asia, https://www.climatecentral.org/news/report-flooded-future-gl...

Suggesting that people who are both biologically and culturally adapted to hot, equatorial climates migrate to Antarctica as a primary solution to this displacement strikes me as absurd.

Having said that, I think colonizing Antarctica will certainly be a thing, but mostly for resource extraction, not for habitation of tens of millions of displaced poor people.

The article mentions that "on record" only covers the last ~40 years 5 separate times, including in the first sentence and visually in a graph. Is there any way it could be more clear? It also says in the subtitle and body that this change is probably not due to global warming. How are you reading it as an "effort to drive anxiety of extinction"?

It's honestly hard to imagine a more mildly-framed climate-related story that is still accurate. Do you have an example of some climate-related coverage that you find acceptable?
