International Online Zhuangao: According to British "Daily Mail" reported July 27, as U.S. President George W. Bush during the White House had to delete the scientific reports on global warming, part of, and limit public mention of this topic, or even to conceal evidence of global warming. Recently, the Obama administration declassified some top-secret photographs of the year, including global warming in Alaska, the devastating effects of pictures.

These photos in the Bush administration has been classified as top secret, has recently ordered the exposure of Obama. One of the pictures taken in July 2006 shows that Alaska's Chukchi Sea coast there is still a large number of sea ice; while in July 2007 photographs show that there are no more ice in seawater.

These photographs suggest that the disappearance of sea ice in the summer of 2007 than in 2006, more than 1 million square kilometers, global warming is changing the Arctic environment and climate. NASA Goddard Space Flight Center索尔森马库斯said: "These photos are taken the ratio of 1:100, you can clearly see the Arctic summer, the huge picture, it makes us feel so frightens the . "

2008 was even worse than in 2007, 2009, sea-ice extent be further reduced. Scientists warned that the loss of summer sea ice indicates great danger, many animals rely on ice shelves to survive will face severe threats. Sea ice as polar bears hunting seals and sea food platform, a large number of polar bears disappearing means that these animals will face a similar threat of starvation. In addition, the sea ice can reflect solar radiation, a large number of disappearing sea ice, the Arctic waters of the rapid increase in temperature may then lead to accelerated global warming.

President Obama has called for the United States Congress and the Republican Party to take action, through measures to mitigate the threat of global warming. Obama has been appointed as the National Oceanic and Atmospheric Administration biologist Jane Lubchenco to head the new Secretary, said: "We need to do now is to act quickly, ongoing climate observation, close attention to the current danger."
