Besides carbon dioxide, there are two other gases that accelerate global warming. Both are methane and nitrogen trifluoride derived from ancient plants and technology, flat-panel screen.
According to observers environment, the gas is the second cause greenhouse gases such as carbon dioxide. In fact, both gas gives almost the same effect like the carbon dioxide caused. Recent research shows in the past few years, the second gas effect is increasing outside estimates. The weather increase also surprised observers.
This methane gas is still the biggest concern after carbon dioxide. The gas is considered a greenhouse gas effect after the second based on the amount of carbon dioxide warming effects and the number produced in the atmosphere.
Methane comes from natural gas, coal mining, and sewage plants. The most worrying scientists is that the plants decompose. Several thousand years ago, billions of tons of methane formed from decaying vegetation in the Arctic North Pole. Plants that decompose and become immobile on the seabed. When the north pole start warming, methane stored in the seabed can accelerate the warming in the area.
Scientists have been trying to learn how the process will begin. Currently, the data collected are still preliminary data, there has been no conclusion. But the scientists said what they see in the beginning is the beginning of the release of methane in the polar north.
Based on their observations, in the last eight years the rate of methane in the atmosphere is still stable, it is estimated that every 40 minutes by supervisors monitor near the seaside cliffs. But in 2006, the results indicate increasing of methane gas. The amount of methane gas in the air jumped from around 28 million tons in June 2006 to October 2007. Currently, the number has reached 5.6 billion tons of methane in the air.
“If this continues to happen, then the effect will be worse,” said MIT scientist atmosphere Ron Prinn, head of the study methane, as said in the geophysical journal Research on Oct. 31 edition. “When the rate of methane continues to increase, of course, will accelerate climate change,” he said.
On the other hand, the rate of nitrogen in the air triflorida is estimated to increase fourfold the last few years, and 30 times since 1978. However, the increase was only contribute 0.04 percent of the total effect of global warming caused by carbon dioxide. Gas is usually used as solvents, such as in manufacturing television and computer monitor, and the panel.
The nitrogen triflorida with the scale of the dihiting per trillion in air during this threat is considered insignificant. According to Ray Weiss geophysics professor at the Oceanographic Institution, an initial effort to know the amount of gas in the air to diremehkan considering the amount that is not too large.
But gas is actually classified as one of the gas that is more dangerous because hundreds of times more powerful than carbon dioxide. Meanwhile, methane is 20 times more harmful than carbon dioxide from per molecule basis. Carbon dioxide gas that is still the most dangerous because the measure is very high and fast growth.
According to scientists, environmental Orjan Gustafsson of the University of Stockholm, a survey this summer found the rate of methane in the east Siberian Sea increased from 10,000 times higher than normal rate. Scientists in the field of environmental Stephen Scheneider from Stanford University, also warned the increase in two gas is a new phenomenon.
“We need to be sure with all these new things as a global trend that needs to skeptical,” he said.
