Title: Climate 'tech fixes' urged for Arctic methane
Description: Scientists told UK MPs this week that the possibility of a major methane release triggered by melting Arctic ice constitutes a "planetary emergency".

My Notes
--------
The BBC Science and Environment article, by Richard Black, discusses several connected ideas.
The basic scenario is::
global warming causes
increased melting of Arctic sea-ice, which causes
release of frozen methane from the Arctic sea-bed, which causes
more global warming
The specific news event reported by the BBC, is that a British engineer suggested to Parliament that it may be possible to cool the Arctic enough to prevent this run-away cycle, by building::
100 or more towers pumping seawater droplets into the Arctic atmosphere
