Alaska climate change and decreasing in population My name is Zachary Rowe, I am going to talk about the global warming weather effects in Alaska and how it has affected the population of various living animal species. The number of large predators living in the southern Beaufort Sea of Alaska has decreased from 1,500 animals in 2001, to just under 900 in 2010. As the species are decreasing in numbers, they are now listed as vulnerable by the International Union for the Conservation of Nature. Another problem in 2013, a report by the National Oceanic and Atmospheric Administration have seen a decline in reindeer inside Alaskan boundaries. These aren't the only species whose populations has …show more content…

The National Oceanic and Atmospheric Administration have observed that approximately one million reindeer were alive in 2000, now in 2013 only 700,000 units remain. Also, scientists have recorded that many ranging deer herds are significantly smaller than they have been in the past several recorded years. In 2012 the International Fund of Wildlife’s according to the national geographic Jeff Flocked said, “There has been roughly a 60 percent decline from historical high levels, and that the decline was caused by suspected climate change”. Researchers in Finland have found that the grazing of a reindeer could help prevent solar heat absorption, which in the result; can lead to climate change temperature swings. Scientists have also found out that in areas where reindeer don't graze there are higher levels of heat radiation. Wooded areas are showing that the levels of shrubs and trees have also absorbed heat. Swedish scientists has found that reindeer can also prevent the climate change caused of a spread of invasive species in the Arctic Tundra. A study from Redlist Industrial Development and Human Activity shows that poaching animals are also major threats to the reindeers
