Climate Change study predicts hazy future for Europe's birds
14-01-2008
On January 15th, BirdLife International welcomed the publication of ' A Climatic Atlas of European Breeding Birds'. This Atlas marks a major advance in understanding the potential impacts of climate change on wildlife. It shows that in the course of the 21st century the changing climatic conditions will force most species to move into new areas. For many of them this will prove difficult, and combined with other threats this will increase their risk of extinction in Europe.
The study, based on the use of 'climate envelope modelling', predicts that without vigorous and immediate action against climate change, the potential future range of the average European bird species will shift by nearly 550 km north-east by the end of this century and will reduce in size by a fifth compared to the current range. For some species, the potential future range does not overlap with the current range at all. Arctic and sub-arctic birds and some Iberian species are projected to suffer the greatest potential range loss. Projected changes for some species found only in Europe, or with only small populations elsewhere, suggest that climate change is likely to increase their risk of extinction.
The Climatic Atlas not only shows maps of the potential range of each species breeding in Europe at the end of this century, it also provides ways of responding to this challenge. Most of all we need to protect and restore today's wildlife, and secure healthy populations of birds within their current ranges. Central to this will be the strengthening of Natura 2000, the European network of protected areas. The sites must be better protected, managed and connected to provide a 'backbone for biodiversity' and to accommodate the expected changes in distribution. At the same time, the landscape outside these areas must become more 'permeable' to species movements by providing stepping stones of high quality habitat and by more sustainable land-use policies.
Dr. Clairie Papazoglou, Head of the European Division of BirdLife International concluded: "The implementation of the EU Birds and Habitats Directive across the EU is a precondition for helping our wildlife against the impacts of climate change and for supporting Europe's ecosystems on which we depend ourselves if we want to come through the climate crisis."

这个欧洲繁殖鸟类气候地图的一些补充资料:
随着气温的上升, 四分之三在欧洲繁殖的鸟需要向东北面转移, 减少牠们在欧洲出没的地方的面积. 在本世纪末, 一般鸟类需要向东北转移的距离约560公里, 一些在英国的外来和少见的鸟种, 例如主要在欧洲大陆, 非洲西北面和地中海出没的戴胜, 将成为英国的留鸟. 既然气候变化能影响鸟类, 它对人类的影响将不容忽视.

其中有一个理论是,地球变暖导致北美洲北部冰川溶解,注入北太平洋的淡水增多,会改变墨西哥湾洋流的流程,所以,欧洲不是变暖,而是变冷啊(不要忘记英国的纬度相当于纽芬兰),到那时候可能是北极圈鸟类增多,而英国的观鸟人是双腿发抖的看鸟吧?
