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

Global Sea-Level Rising: Polar Ice Caps Essay

1048 Words5 Pages

The impact humans are having on mother Earth is increasing its effects with the rising of sea levels. Global warming is causing polar ice sheets to melt, which is a major cause of adding volume to our oceans. Furthermore, the troposphere thickens, due to greenhouse gases, increasing the amount of radioactive waves that causes the seawater to warm up, resulting in ocean expansion. Most climatologists are expecting a rise in oceans around the world to be between 1.5 and 5 ft by the end of this century.(Harkinson) Some members of our society feel that because climate change is not certain, they are not willing to make a difference to help. Many people are unaware of how rapidly we have impacted mother Earth. The melting of the polar ice…show more content…

(Gardiner) The melting of the polar ice caps affects the whole world.
Coastal lands, agriculture, weak permafrost, increase in disease, weather patterns, ocean circulation, and biodiversity are few elements affected by this emergency. There is major concern for coastal flooding. IPCC estimates that 43% of coastal wetlands will be asphyxiated, beaches will wear down 100 to 200 ft., and 5,000 square miles will be overwhelmed with sea water. (Greenpeace) In Chesapeake Bay, beaches have already been lost, resulting from more than an inch increase in sea level. Many islands and low surface level countries will be inundated . Millions of people could be affect in Bangladesh, China, and New York due to flooding. Any country with a small economy can suffer greatly being unable to adapt and replenish resources. Pests that use warm weather will have more time to reproduce and feed on infected species, usually passing on infections. Allergens and viruses will be more persistent. Forest fires will increase. An example for agriculture damage is Kansas’ ability to be 4 degrees warmer during winter which is bad news for the winter wheat grown with cold air usually sent southward from the Artic ice. Also, during summer Kansas can lose valuable cropland from soil losing 10 percent of its moisture. (NRDC) Shrinkage in fresh water supply will result in water stress for people that rely on spring water, such as the Himalayans
