Evidence That There Is Global Warming
By: Owen & Jacob
Looking Back Into The Past
Trees- Trees store information about the the climate in the places where they are located.
Ice- Scientists drill into the core of large ice sheets. Tiny bubbles trapped inside the ice are actually little pieces of earth's past atmosphere, frozen in time.
Lakes and Oceans- Pollen, creatures, and particles fall to the bottoms of oceans/lakes each year forming sediments. Sediments preserve all these bits and pieces which scientists study to learn about the air and water in its time.
Temperature Rises
During the last few years scientists have noticed a large increase in the earth’s temperature. (See Graph #1)
Seawater Warming
Warming Oceans
The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 2004.
Rising Water
Global sea level rose about 17cm in the last century. The rate in the last century is nearly double the height that it was in the century before it.
Melting Of The Ice Sheets
Greenland’s ice sheets have decreased in mass by 150-250 cubic meters per year from 2002-2006, while Antarctica has lost 152 cubic kilometers of ice between 2002-2005.
NON- Global Warming Believers
I know you think of global warming as a light thing, right? Well what if everything doesn’t turn all right? Why let this pass through without preparing for the worst? This Abrupt storm could be the end for many animals…. and for what? So we can fuel our stupid cars! NON believers you don't just not believe in global warming. You just choose not to believe it and
turn your back on reality and on all the other animals lives you're just throwing away.. Think about it
THE END
