American State

According to scientists, the study will give a clearer idea of what climate change can be expected with accumulation in the atmosphere of carbon dioxide caused by industrial human activities. Because of global warming are less migratory birds fly south for winter spent watching the life of the Pacific black geese in Alaska, biologists have concluded that these birds have in recent years rarely solved on long flights for the winter to the shores of the Gulf of California. This behavior of birds, scientists explain the fact that now the climate in Alaska has become softer, and the once barren lagoon of the American State each year become more and more attractive: the winter is getting warmer, start grow plants that can feed the birds in winter. Over the past 30 years the number of geese who have refused to trip south increased from 4 to 30 thousand, and it is about 30% of the population of this species of birds. Warm weather in the area of habitat geese has reduced the amount of ice, there was more food for birds in the form of sea grass. The warming of the planet forcing birds to abandon long-distance flights for the winter in warmer climates.

In addition, as they note, wintering in the north, the birds may return earlier than the other to breeding grounds, and consequently, faster raise offspring. Confirmation – increasing brood of birds remaining in the winter in Alaska. Scientists offer to turn the Sahara into a tropical forest researchers presented a new project to combat global warming which involves the conversion of the Sahara desert to tropical forest.
