Antarctica melts, Africa dries: Two new scientific studies on climate change are predicting a massive melting process at the icy South Pole and warn of severe water shortages in the third-largest continent on earth.
Antarctica melts: Contrary to expectation, the ice is shrinking at the South Pole by climate change, to grow instead. Since 2002, the Antarctic has to measurements by U.S. researchers annually lost up to 152 cubic kilometers of ice - the equivalent to 50 times the water consumption of the ten-million-metropolis of Los Angeles.
The UN IPCC (Intergovernmental Panel on Climate Change) in 2001 had just predicted the opposite: According to his forecast, the Antarctic ice shelves in the wake of global warming in the 21st Century to grow because of climate change there also increasing rainfall is expected. The massive melting process takes place mainly at the ice sheet in West Antarctica, Isabella Velicogna and John True Report of the University of California in Pasadena on the basis of satellite measurements. Every year he had raised sea levels globally by about 0.4 millimeter, they write in the journal Science (DOI: 10.1126/science.1123785). But this western ice sheet would thus the sea level by about seven meters, lift it if it were to melt all over again. Even worse would be the Erosion of the ice sheet in East Antarctica: it is eight times larger than the western.
This is the result of a study. Weils halt grad so nice to be a car salon with the ever-increasing boxes passt.Wie in this forum has already written more often, will the climate change with us due to the slowdown of the Gulf Stream in increasing external cooling. But who now says he would end up with walk out to the south, has cut herself. By rising sea levels of living space in Italy is considerably reduced, and even further south is as follows:
Africa however, threatened with a unchecked emissions of greenhouse gases a dry future. By the end of the century a quarter of the continent is likely to be haunted, according to a study of South African researchers from severe water shortage. The also of "Science" (DOI: 10.1126/science.1119929) study published estimates are that many rivers and lakes dry up for lack of sufficient rainfall. Worst hit were densely populated areas in the south and west of the continent and regions on the upper reaches of the Nile.
For the calculations, the researchers linked to Maarten de Wit and Jacek Stankiewicz of the University of Cape Town data on Africa's rivers and lakes with different climate change scenarios. You divided the continent in to a grid of 37 squares, for which the annual rainfall were examined separately. Scientists warn to the fact that politicians in countries with transboundary waters in the future more than ever need to regulate access to the precious liquid.
Merry prospects.
The bad news is growing, but still lacks very many of our fellow citizens to realize that it can not go on as before. It is itself the question: Does driving blind or stupid? Or both?
