Message: <blockquote data-quote="jurek" data-source="post: 1599101" data-attributes="member: 3357">Yes and not.The details are not agreed upon. For example, 5 years ago scientists seriously considered the rise of sea level of as much as 8 m, or switching off the North Atlantic current circulation which would start the next ice Age. Both scenarios are now considered unlikely.And these 'little details' are of outmost importance if other scientists estimate the effect on birdlife, on human economy, or on counter measures.Yes, precisely. And it is most important to look criticaly at various propositions of governments to qchieve this.Yes, precisely. Shorter migration is usualy beneficial for birds - less dangers. That's why I objected to pushing the news about the black brant into 'because it is different it must be a danger'.Every public debate, needs objective information - although some well-meaning activists try to turn everything into propaganda.</blockquote>
