Sounds pretty serious, and carefully judged.
The ozone hole was a dramatic story that affected political and economic judgements world wide.
This story of open sea water at the North Pole looks decisive. It can be easily pictured mentally. It will grab the imagination of decision makers. As a result it will become impossible for them to think of capitalism in a purely laissez faire manner without a framework for environmental responsibility.
In turn this has implications for would-be revolutionary socialists. The enemy will be dealing in reforms and environmental responsibility, if not social responsibility.
There is no point in supposedly revolutionary strategy that refuses to tackle capitalism on the terrain of reforms.
