Us and Global Warming

The global warming, the warming of the earth temperatures. This has already been dealt with in detail in the recent time, and the scientists are trying to find ways for that to slow or stop global warming.
The biggest problem with global warming is to know how to do it in the world balance throw. With the warmer temperatures and increasingly hot, it can begin to make the ice cap, and let the harmful ultraviolet rays of the sun PO These effects will cause immense damage to the earth and how we live life.
Greenhouse gases are the gases present in the atmosphere which reduce the loss of heat into space and therefore contribute to global temperatures through the greenhouse effect. Greenhouse gases are essential to maintaining the temperature of The Earth; without them the planet would be so cold as to be uninhabitable. However, an excess of greenhouse gases can raise the temperature of a planet to lethal levels, as on Venus where the 96.5% carbon dioxide (CO2) atmosphere results in surface temperatures of about 467 °C (872 °F). On earth, the term greenhouse gas is applied to, in order of relative abundance: water vapour, carbon dioxide, methane, nitrous oxide, ozone and CFCs. Greenhouse gases are produced by many natural and industrial processes, which currently result in CO2 levels of 380 ppmv in the atmosphere. Based on ice-core samples and records (see graphs) current levels of CO2 are approximately 100 ppmv higher than during immediately pre-industrial times, when direct human influence was negligible.
