Volcanic eruptions that emit lava and clouds of volcanic ash up to several kilometers into the atmosphere it takes a lot of carbon gases. But a research study found that the environmental impact caused by the volcano was much lighter than human activity. According to research, carbon dioxide (C02) produced by humans in three to five days can equal the amount of gas that was brought around the volcano on earth for a year.
"Carbon dioxide emissions anthropological pogenik make global C02 emissions volcanoes seem very small," said Terrance Gerlach, study researchers from the United States Geological Survey (USGS). C02 is the main greenhouse gas responsible for climate change.
Gerlach describes the amount of carbon dioxide released a volcano erupting in several previous studies, namely 0.13 to 0.44 billion tonnes of C02 per year. For comparison, the rate of human C02 emissions for 2010 alone reached 35 billion tonnes.
Human activities that release carbon gases is large enough. Land use, for example, release 3.4 gigatons per year. Motor vehicles, like cars and trucks, spraying 3 gigatons each year. Production of cement supply the 1.4 gigatons of greenhouse gases into the atmosphere.
In Eos, the weekly newspaper of the American Geophysical Union, Gerlach wrote that human carbon emissions could even surpass the current C02 emitted by the eruption of a volcano, including a giant eruption of Yellowstone National Park in the United States. Volcanic eruption events of that very rare, and unusually large explosion was occurred in the last 74 thousand years ago in Indonesia.
The researchers calculate, to match the human-generated C02 gas, it takes more than 850 cubic kilometers of magma per year. For comparison, Lake Ontario in Canada holds about 1640 cubic kilometers of water, while the capacity of the reservoir Jatiluhur about 3 million cubic kilometers .*** [LIVESCIENCE|KORAN TEMPO 3566 ]Tuesday, July 5, 2011
Humans spend a lot more CO2 than volcanoes
