The thickness of ice on the north pole is tend to decreasing each year on. It even reach its lowest point on summer 2007. This is a serious fact of the global warming.
The ice thickness on summer summit last year is about 23 percent lower than the minimum level of 2005. If the trend continues, it is not impossible that predictions of some experts will come true that whole ice on arctic will melt on summer.
Christian Haas from Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany along his teammates estimated the sea ice thickness during summer in 2001, 2004, and 2007. They discovered the average thickness during summer 2007 is 1,3 meters. As comparation, the thickness of ice is 2,3 meters on 2001, and 2,6 meters on 2004.
The team left for the arctic with the ship RFV Polarstern on august and september of 2001, 2004, and 2007. Meanwhile, they use helicopter-borne to measure the ice thickness. Before that glassiologist measuring the ice thickness directly above it. According records, the ice thickness in 1991 is 3,1 meters.
We must unite in real action to slow down the speed of global warming by living a simple life, simple life means less energy, less waste, less garbage, and less carbondiocside. The key is simple, stop being greedy.
