  • **FILE** Philipino farmers plow their rice fields in San Fernando, Philipines as nearby Mount Pinatubo erupts with smoke and volcanic ash in a Monday, July 8, 1991 file photo. The Pinatubo eruption shot so much sulfurous debris into the stratosphere that it is believed it cooled the Earth by .9 degrees for about a year. This precedent is noted by some scientists who have suggested that, if the sun warms the Earth too dangerously, the time may come to deliberately launch a layer of pollutants into the atmosphere to cool the planet.
