In this year global warming has caused a drastic increase in temperatures, which made this winter season much hotter than years before. Some studies have found that this increase in temperatures can have small benefits in America. According to an article by the Associated Press, the benefits can be related to the increase in physical activity by people who would be more inclined to leave their houses and enjoy the warmer weather outdoors. However, this global warming side effect will not be beneficial for everybody. In some states such California, Nevada, and Arizona these high temperatures will keep people inside their houses.
The Barnes Ice Cap, considered the last remaining piece of the major glacier Laurentide Ice Sheet that once blanketed Canada and much of the northern United States is being threatened by global warming a new study says. In a recent article by Brian Kahn at ClimateCentral.org, he wrote “Humans are in the process of changing the planet in a way that hasn’t happened in 2.6 million years.”
The ice cap reached stability on Baffin Island 2,000 years ago. But rising temperatures has made the island stable no longer, and as a result, the bowling pin shaped Barnes Ice Cap is becoming smaller and smaller. The ice cap started getting smaller at a steady pace around the 1990’s and as of now, is only the size of the state of Delaware. The blame is attributed to human carbon pollution which has driven up global temperatures. Scientists say if rising temperatures keep up at the same pace, the Banes Ice Cap will be gone in 300 years.
Africa is the continent which is facing terrible consequences due to the climate change. According to the article written by Claudia ten Have of United Nations University, published in July 06th 2008, titled “Africa and Climate Change”, many deleterious changes from climate change is to be expected for the future. According to Claudia, “Africa is set to experience:
- Significant increases in temperature by 2010, particularly in the Sahel and part of southern Africa;
- Dramatic decreases in precipitation, declining by more than 20% compared to levels 20 years ago; and
- More frequent and intense tropical storms—parts of the continent will see a 20% increase in cyclone activity.”
It is urgent that the leaders from each part of the world contribute in the amelioration of greenhouse gases.
