Re: Antarctic sea ice hits lowest minimum on record
#2Important point is that the amount of area covered by sea ice, which as can be seen in the graph has been relatively stable, is often used as a talking point when arguing that climate change has not been happening. However the total mass of ice has been in steady decline:

In other words while the extent/area has been relatively stable, it has been getting thinner.

#3I 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, which can happen again, but the relentless effort to drive anxiety of extinction through the human race just feels so non-helpful to me.

20,000 years the sea was 130 meters lower.

#5Pardon my crudity, but is there a reason to not build a bunch of nuclear power plants + carbon suckers powered by electricity?

#6If 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 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) higher in the Early Cretaceous and roughly 200 to 250 metres (660 to 820 feet) higher in the Late Cretaceous than at present."

Do you want every article about climate change to include at 10 page essay about the geological history as we know it, how we know the current warming is caused by human activities, and what happened during past rapid warming events and what their causes were?

That sounds like it would hurt the oil industry and the reactionaries that prop it up have somewhat of a monopoly on force.

Do we even have an efficient way to extract carbon using electricity?
