Solar geoengineering — climate-solution or Pandora \'s box?...

[Fred Bloggs]

The science already has enough experience with vulcanism to bound the so-called risks of this last chance technology. Unfortunately, the path to action is being obstructed by the worthless job justification types.

\"It may sound reckless, but proponents point out that we already pump about 10 times more aerosols into the lower atmosphere, as a result of regular pollution. This too has a cooling effect but is associated with other health and ecological hazards.\"

10x refers to \"The principle was demonstrated by the 1991 volcanic eruption of Pinatubo in the Philippines. Its blast was so powerful that it injected about 15 million tons of sulfur dioxide right into the stratosphere. The eruption cooled the planet by more than half a degree Celsius over the following two years.\"

Dumping SO2 into the stratosphere is dramatic and quick-acting, so all the snake oil merchants love it.

Crushing millions of tons of dolomite and spreading it on beach or croplands everywhere would soak up enough extra CO2 to solve the problem permanently, and without side effects, but it isn\'t as quick and it isn\'t flashy.
