We have all heard about how CO2 is causing the earth to become warmer and humans are being blamed for it.
Since 1980, scientists have monitored geologic unrest in Long Valley Caldera and at adjacent Mammoth Mountain, California. After a persistent swarm of earthquakes beneath Mammoth Mountain in 1989, earth scientists discovered that large volumes of carbon dioxide (CO2) gas were seeping from beneath this volcano. This gas is killing trees on the mountain and also can be a danger to people. The USGS continues to study the CO2 emissions to help protect the public from this invisible potential hazard.
A preliminary estimate of the current rate of CO2 gas emission at Mammoth Mountain is 1,300 tons per day. Similar rates of CO2 emission have been measured from the craters of Mt. St. Helens (Washington) and Kilauea (Hawaii) volcanoes during periods of low-level eruptive activity.
With sun spots, volcanos, etc. why is man being blamed?
