Glaciers, Ice and Global Warming Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world. The numerous ice ages documented on this planet that have shaped its contours, offers us incredible…show more content…
It has reached the point in human evolution, with facts proving a half degree Celcius increase in the past century, with more exponential increases expected for the future. One half degree doesn't sound like an overwhelming amount, but just the sheer magnitude of humans being able to change GLOBAL temperatures is astounding. There are several reasons for this global warming crisis namely the presence of greenhouse gases and the depletion of the Ozone by tricky synthetic chemicals such as CFCs. Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives. Global warming should be one of the gravest concerns to the future of human kind and making an effort on every individual level will decrease the factors that have the greatest impact such as combustion emissions and hazardous chemicals. No scientist would deny the increase and temperature and none would stop at even saying that the problem will only increase exponentially. Along with greenhouse gases and CFC (Chloroflorocarbons) humans must realize that they are very significantly at the heart of the crisis. Not only does this threaten coastline properties and the health of the planet overall, habitats
