Solar Geoengineering to Cut Warming
Adding Calcium Carbonate to the Skies to Fight Global Warming Source: 1991 US Govt. Photo of Mt. Pinatubo Erupting Harvard University Research Harvard researchers have a unique& innovative remedy to stall Global Warming. Add calcium carbonate to the atmosphere. Calcium carbonate is used in antacids. They believe it could cool the planet and help to slow Climate Change. The concept is based on the impact of volcanic eruptions on the atmosphere. Modeled on Volcanos Erupting The idea is to block sunlight or deflect it from the earth's surface. It's based on what happens from volcanic eruptions. The volcanos spew sulfur particles into the atmosphere and the particles cause sudden, though temporary, changes to the global climate. An example cited by the Harvard researchers is the 1991 eruption of Mt. Pinatubo in the Philippines. That event caused temperatures in the Northern Hemisphere to drop 0.6 degrees Celsius.
