对许多人来说,全球气候变暖似乎距离他们还很遥远,但这种气候现象却被认为正在改变北极熊的行为习性.因为人类大量使用化石燃料,导致温室效应,北极冰川融化,导致北极地区固体冰减少,北极熊被迫要在水中停留更长时间.
研究人员通过监控北极熊的活动,跟踪它们的行为,来确定气候变化对北极熊的影响.研究人员在跟踪时发现成年北极熊会把小北极熊驮在背上游过冰冷的海水.这是他们第一次发现这种现象,研究人员认为,这是由于北极地区在夏天冰雪融化,北极熊只好进行更长距离的游泳,致使小北极熊不堪重负,只能趴在妈妈背上旅行.趴在妈妈背上意味着幼仔能够直接与妈妈的皮毛接触,而且身体大部分将远离冰冷的海水,从而减少它们的热量损失.鉴于北极熊幼仔还没有长出足够多的脂肪以对抗在海水中长时间游泳时需要面对的严寒,所以,这种做法对幼崽的生存至关重要.
北极熊常常在海冰的冰面之上进行捕猎和繁殖活动,而近年来,北极海冰面积却在逐年减少.随着北极冰雪不断融化,北极熊游泳的距离可能会不断增加.这让北极熊的生活充满危险.
作为普通市民,我们应当从现在开始推崇低碳生活,遏制气候变暖.为北极熊的生存尽一份力.

For many people, global warming seems far away from them, but this climate is deemed to change polar bears' behavior. Because human use a large number of fossil fuel which leads to the greenhouse effect, the glacier in North Pole is thawing. Reduce of the solid ice compels polar bears to stay in water for longer time.
Researchers confirm the influence of climate change on polar bears by monitor and tail their behavior. Researchers found that adult polar bears would carry baby polar bears on their back to the other side of the cold sea. It was the first time they have ever saw this behavior. Researchers thought that was because polar bears have to swim a longer distance for the ice in North Pole thaws in summer so that baby polar bears have to stay on mother's back. Baby polar bears could contact with mother's fur and put most part of their bodies far from the cold water by this way to reduce the loss of the calorie. This behavior is considerable crucial for cubs' survival as they have not enough fat to Resistance to cold when swimming for a long time.
Polar bears always hunt and breed on the ice surface. However, the ice area in North Pole is decreasing year by year. With the thawing of the ice in North Pole, swimming distance of polar bears may continue to increase, which cause danger to them.
As ordinary citizens, we should promoting low carbon life now to restrain the climate warming and make an effort on survival of polar bears.
