IlmuPengetahuan.Org - Scientists have spent decades figuring out what makes the cause of global warming (Global Warming). They have seen the natural cycles and events that are known to affect the climate. But the amount and pattern of warming that has been measured can not be explained by these factors alone. The only way to explain the patterns to include the effect of greenhouse gases emitted by humans is to examine what causes the greenhouse effect itself.
To bring all this information together, the United Nations formed a group of scientists known as the Intergovernmental Panel on Climate Change (IPCC). IPCC meets every few years to review and share the latest scientific findings and write reports and summarizes all that is known about global warming. Every report that reported a consensus or agreement among hundreds of leading scientists are members of the IPCC.
One of the things studied by scientists that greenhouse gases are responsible for global warming. Most biggest contributor comes from burning fossil fuel vehicles, factories and electricity production. Gas responsible for global warming in large part to the carbon dioxide (CO2). Other contributors to the methane released from landfills and agriculture (especially from the feces of farm animals), Nitrous oxide (N2O) from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests.
In order to deal with the impact of global warming, scientists tend to discuss about all the gases generated by the greenhouse effect. Since 1990, yearly emissions have gone up about 6 billion metric tons of CO2 worldwide, an increase of more than 20 percent.
