Global Warming and our Earths Systems

Illustration 1: Marine Bio. The Greenhouse Effect. 1990. Photograph. Our Earths population is getting bigger and bigger everyday. More people being added means more CO2 is being added and that is a huge pollutant to our Earth. Every year three billion metric tons of CO2 are added to the atmosphere every year (“Global Climate Change” ). Pollution has increased atmospheric concentrations of water vapor, carbon dioxide, methane, and all greenhouse gases that help trap heat near Earth’s surface (“Effects of Global Warming” ). The heat is shifting rain patterns and is causing animals to become endangered and go on the move. Global warming has been a threat to our environment and ecosystems for years but now that threat is becoming even greater. In the 1700s people started to admit large amount of greenhouse gases (“Basics of Global Warming” ). Greenhouse gases were being admitted because fossil fuels were to run factories and power plants. We have been burning a huge amount of fossil fuels to run our cars, planes, factories and power plants. All of these things to more and more gases being added to our atmosphere. The gases stay in the atmosphere for centuries, and the more gases being added are being built up and is create an extra big heat blanket around the world (“Basics of Global Warming). Global warming is warming the planted from north to south and everywhere in between. The worlds mercury is up for than 1 degree Fahrenheit and the effects are seen even more in the polar regions(“Effects of Global Warming” ). The Alps southern regions are receiving 10% less rain 10 years and its northern regions are facing flooding(Alexander). The snows of Mount Kilimanjaro are beginning to melt and disappear. Since Australia is experiencing a big change in its climate,it is putting the Great Barrier Reef at risk. Frequent flooding is happing and is wipingout our crops, spreading disease and killing out homes of humans and animals. Since the planet is getting warmer so are the seas. The warmer the seas are getting are causing stronger hurricanes. Hurricanes in the Atlantic Ocean have been more frequent more than ever in the last decade(Alexander ). Even though Global warming and its effects are seen in the Polar Regions, it is making a great effect in the Sahara desert. Rising temperatures are causing the Sahara desert to expand and it is eating our farming and...
