Sue them into oblivion.
Luckily for us I believe they will make all the same mistakes as they made in climate change research, and fail to assess the scale on which the global atmosphere responds to small inputs of various kinds (such as greenhouse gases, clouds over San Francisco, etc). They are going to need to send so much salt up into the atmosphere that they will create a huge carbon footprint at source! — thus cancelling out whatever they gain. It will probably just end up prolonging the June gloom around coastal Cali into early July. Big deal.
Big.
Deal.
