Mail & Guardian: Governments remain silent about bids to geoengineer the climate

„Unwilling to do more to stymie global warming, governments have turned to geoengineering. This covers anything that changes weather patterns, helps to store carbon emissions, and stops the sun’s rays coming through the atmosphere. The activities range from spraying chemicals into the sky to create rain clouds to putting mirrors in the atmosphere to reflect the sun’s rays. One experiment in Canada — a rare case of these being made public — involved dropping iron filings into the ocean to kill plankton so it would sink to the bottom of the ocean and trap carbon dioxide.“
