Dangerous effetcs of Global Warming

Global warming effects have occurred in many parts of the world. More frequent disaster such as storm and flood, drought, and the decrease of agricultural yields are just some examples of it. The news is getting worse when Drew Shindell, at NASA Goddard Institute for Space Studies, New York stated that methane has more global warming effect when combined with aerosols. He ran a range of computerized models to prove it.

Aerosols can be defined as a suspension of fine solid particles or liquid droplets in a gas. Aerosols are generated naturally from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Ten percent of the aerosols are generated by human activities, such as the burning of fossil fuels. In the atmosphere it refers to atmospheric particles such as dust, sea salt, sulphates, smoke and black carbon.

Methane is creating global warming effect 25 times more than carbon dioxide, this statement is supported by The International Panel on Climate Change (IPCC) and treaties such as Kyoto Protocol. It means that with the same volume, methane is able to warm this planet 25 times more than carbon dioxide. The condition is worse when aerosols are also present in the atmosphere. The relative global warming potential (GWP) of methane is significantly increased to 33. It means that the actual effect of global warming is worse than calculated before. We miss one important fact here, that the mixture between aerosols and methane will increase the global warming effect.
