A Modest Proposal For Sequestration of CO2 In the Antarctic

First time accepted submitter Alienwise writes "Judith Curry reports a scientific concept of an atmospheric CO2 sequestration plant. It would be based in the Antartic to profit from the cold weather, which would facilitate the creation of CO2 snow — which would then be buried. The plant could be powered by windmills." The lead author has agreed to let Curry link to a copy of the final manuscript, if you'd like to read more.

I had wondered about artificially creating methane hydrate crystals either for storage in deep water or to be used as a cleaner fuel source. They should burn as clean as natural gas. I'm not a hundred percent sure of the process but I believe cold and pressure would cause the crystals to form so it'd involve mostly pumping CO2 into the deep ocean. You'd probably want to keep it semi closed to avoid raising acidity of the ocean water. I never liked the idea of underground storage since some of the biggest disasters in known history have been caused by major releases of CO2. Hydrate crystals are really stable so long as the temperature is stable. Raising deep water temperatures one degree would involve such a massive increase in global temperatures we'd all be dead anyway.

Be careful. If you overdo it, you'll kill billions by inducing an ice age. There's evidence these can come on in as few as a couple of years.

Global warming is moving in from the seas over 100-300 years. Nobody dies.
