Resumo de The Makers Of Rain :history And Futur Impact Of Climate Changing

The antartic fauna fells intensely the effects of climat changing.

The population if the emperor penguin are twice time less numerous that there are thirty years, while the numbers of penguin of the Adélie land have decreased of seventy per cent during the same time. All that because of krill who reduce enomrely and that depend the species who eat them, as a whale, seal, albatros, penguin and so on...
To measure that the ice mealt , the population of krill (species of penguin) live in the south hemisphere. We have observed the changing in this population after 1976, for precedament, there had no variation to year in year. After 1976, the populations of Krill have decreased of fourty per cent during a decade.
In antartic, it?s the caribou who are the most menaced, because he eats the lichen during the winter ; the lichen is the only food who eaten. The temperature warm , the rain enormous that spring cover of frost the lichens. When the layer inferior frost, the caribou don?t reach the lichen. He must scratch the floor and lift the roots. A long time must past for the reconstitution of lichen.
An other factor who contribute to decrease the herd, is the fact that the modifications of climate to result in the flooding who drown the small animals by thousand, to moment of migration. The white bear is an other species menaced. For found the goods, the white bear has need to large ice which give him his resistance course : the seal. This aminal is a mammal the most numerous in the great Nord.
They are at least 2,5 millions to swim in the cold water by the icebergs. The climate conditions are such that the seals can?t reproduce, can?t built their house of snow on the ice. He leave more to North, certain goes into the Siberian. And the bears? Those who have sufficiently of fat following the seals, but many can?t move and died of hangry.

Each winter is more warm that the precedent, the tall bears died slowly of hangry. Without important falling snow , the females can?t dig their lairs. Even the population of seal in Groenland, whi live in the Saint ?Laurent Golf, are menaced of endanger species. Like the seals ?anneles?, they can?t have the baby if it not enough ice for give birth, that what happen in 2000, 2001 and 2002. This years without progeny , who are cover this century, we must worry us. When the year without ice more long that the live-reproductive of female, as a twelve years maximum, the population is menaced to disapear.
Same the stong walrus don?t espace to power of sea ice, for the limit whether productive the ices, is his principal house. If nothing is done for decrease the diffusion of gas polluting the admosphere , a day will come where they will haven?t the life in Antartic. I will stay a enormous sea dark and stormy. The high of temperatures will give born to the polar desert. After have survived during the millions of years, all the fauna of great North will have disapeared for always.
