New climate theories
Air pollution is an increasing environmental concern, and rising global warming temperatures are not the only consequence….
Climate change is now an indisputable phenomenon. Scientists have identified two distinct and worrying developments. While global warming, which has been predicted for some time, is clearly taking place, there is also growing evidence of global dimming – a reduction of sunlight.
According to BBC Online, the term global dimming was created by Gerry Stanhill, an English scientist who lives in Israel. Stanhill found that sunlight had reduced by 22% in Israel over the past few years. He also noted similar changes in the United States (with sunlight down 10%), in parts of the former Soviet Union (with a reduction of 30%), and in parts of the British Isles (with a loss of 16%) the cause appears to be air pollution.
Climate change impacts humans and animals
Air pollution caused by fossil fuel emissions, will also probably cause a further rise of 0.6 degrees Celsius of global warming, according to professor Stephen Schneider, a leading climatologist from Stanford University in California. He points out that in the past century there has already been a 0.7-degree temperature increase.
According to Schneider, the results will endanger species such as polar bears. The traditional life-style of the Inuit people of the Arctic will also be impacted. At the same time, the British Antarctic Survey has revised its predictions about the col-lapse of the Antarctic ice sheet. It used to be believed that it would remain intact until the turn of the 22nd century. Now there is a risk of a much more imminent collapse.
