New global warming evidence presented

Scientists reported Friday they have detected the clearest evidence yet that global warming is real — and that human industrial activity is largely responsible for it.
Researchers at the annual meeting of the American Association for the Advancement of Science cited a range of evidence that the Earth’s temperatures are rising:
— The Arctic regions are losing ice cover.
— The populations of whales and walrus that Alaskan Eskimo communities depend on for food are crashing.
— Fresh water draining from ice and snow on land is decreasing the salinity of far northern oceans.
— Many species of plankton — the microscopic plants that form the crucial base of the entire marine food web — are moving north to escape the warming water on the ocean surface off Greenland and Alaska.
