Indicator Species Polar bears are one species that are currently feeling the effects of a warming climate. Over the past twenty years, NASA satellite data has shown a 2.9 percent decline per decade in Arctic sea ice, resulting in shorter feeding seasons for polar bears. ...
For example, the Arctic, which is the polar bear's home, is experiencing the effects of global warming more than any other places. As the temperature is increasing, ice sheets are becoming smaller and fewer; as a result, polar bears have to spend more time on swimming in the sea to find icy places for hunting and living, which impacts their reproductive capacities and the cubs' chances of survival (NatureCANADA.ca, 2012). The fact is that the population of polar bear has declined by 22 percent over the past decade (NatureCANADA.com, 2012). ...
In the Sahel of Africa, climate change has caused many trees to die back, exposed sandy soils to wind erosion, and shifted the vast ecological zones of the Sahel, Sudan and Guinea 3southward towards the Equator. The changes of seasons have altered the life cycle events of plants and animals. Climate...
Although scientists have came along with many ideas to reduce our carbon-footprint, we can't realistically make a difference in fixing the issue of global warming because it would be simply too difficult to change the comfortable lifestyle we all seem to live by. On another note, no matter how much ...
