Humans are not causing global warming.

Although the evidence is not yet 100% certain, it is moving in that direction. Top climatologist Stephen Schneider says, "Is there global warming? I'm not 99% sure, but I am 90% sure." Klaus Hasselmann, of the influential Max Planck Institute for Meteorology in Hamburg, says he is 95% certain that the recent increases in global temperature are tied to human-caused carbon dioxide. Much of the evidence is circumstantial, but it is growing, and becoming increasingly difficult to dismiss. For example:

 

The ten hottest years in recorded history (since the 1860's, when reliable measurements began) have all occurred after 1973.Average annual temperatures have gradually been climbing.The polar caps are melting, and giant cracks are appearing in their enormous ice shelves. An 800-square-mile ice shelf called the Wordie has disappeared from Antarctica. A gigantic iceberg the size of Rhode Island also broke off the Antarctic in January, 1995. If even a tenth of the ice in Antarctica melts, it would raise sea levels 12 to 30 feet around the world. (4)Forests are climbing farther north into the polar region, thanks to warmer weather and receding glaciers. There has also been a proliferation of plant life in Antarctica.Disease outbreaks have been increasing all over the world, due to the fact that diseases thrive better in hotter weather.El Nino seems to be staying longer. (El Nino normally arrives every three years; it is an upwelling of warm water from the deep Pacific Ocean that rises up all along the Western American coast. It usually has a profound effect on weather.) For the last ten years, El Ninohas been causing conditions from extreme drought to extreme rain on the West Coast.Marine animals have been migrating to newer habitats. Creatures who normally live in warm water have been expanding their habitat, whereas creatures who live in cold water have been retreating farther north and south.

Answer to: Why is global warming a problem?

1.Climate change is causing sea levels to rise.

 

2. Floods will become more frequent and more severe in some areas, while droughts will similarly become more frequent and more severe in others. Analysis of hurricane activity shows that severe hurricanes are becoming more frequent and more destructive, as a result of increased atmospheric thermal energy. Frequent storm damage to properties will cause insurance premiums to rise until some can no longer even afford to insure their houses.

 

3.Wildlife will suffer from loss of appropriate habitat and from heat stress.

Global Warming Effects on Earth

What is Global Warming- Global warming is the rise in the average temperature of the Earth's atmosphere, caused mainly due to increasing concentration of greenhouse gases in the atmosphere of the Earth. These greenhouse gases are mostly produced as a result of human activity.

 

What is affected by global warming- animals, plants, climate, land... you name it and it will be affected by global warming. In fact, some species of plants and animals are already on the verge of extinction. Studies indicate that around 15 to 37 percent of plant and animal species will be wiped off the planet by the year 2050. Changes in climatic patterns have already started to show, sea level is rising.... to make it short, we are just heading for destruction.
