According to the Native people gathered at UAA today, the problem is devastating. For example Russian nomads claimed that an incredible one million reindeer died in the Russian Arctic over the course of the past decade. It's a massive die-off attributed, in part, to an ironic side effect of global warming, ice.
But in recent years the porcupine caribou of North America and these reindeer herds of Northern Russia have had a problem.
It seems that more and more in recent years, the first snowfall of the season is followed by something unusual in these latitudes, a winter rainstorm. The rainstorm can leave a glaze of ice on top of the snow and that can make it impossible for the weaker reindeer in the herd to punch through the snow for food.
No question. Just from, from what everybody's been talking about today, the indicators are all there and the stories are very, very similar," said Patricia Cochran, Alaska Native Science Commission.
Now many scientists agree with the assessment that the earth is warming and that man is at least partly responsible. One reason they say that is because they can measure the output of the sun and that has actually declined in recent years. With the sun not responsible for the warming, computer models do suggest that greenhouse gases input by man are at least partly responsible for the heating of the earth.
Many scientists say global warming is caused by man and that it is a problem, but some scientists disagree with that. There is no debate of whether the earth is warming. It has been measured. The earth has warmed by one degree Fahrenheit over the last century.
The only issue is about how much is man responsible for. About that there is scientific debate. A landmark report from the United Nations Intergovernmental Panel on Climate Change found in 2001 that man is the prime driver and global temperatures are shooting up faster now than at any time in the past 1,000 years. |
