Is this the new Greenie version of the global warming scare? First they abandoned "global warming" in favour of "climate change". Will it now be "climate unpredictability". I hope it is because that will mean that they have finally got it right
As the climate heats up, scientists expect all sorts of animals to move to cooler places. But that may be easier said than done.
When researchers mapped out the escape routes that a variety of amphibians would need to take in the coming decades to adapt to changing climate conditions, they uncovered some serious trouble.
Because of unpredictable rises and dips in temperature, many salamanders, frogs and newts will get stuck in unfavorable conditions along their travels -- enough to threaten their survival.
The findings are likely to apply not just to amphibians, but also to insects and other types of animals as well as plants. The study adds fire to a longstanding debate among conservation biologists and wildlife managers.
Some experts argue that threatened species need to be bred in captivity or that animals should be moved to places that will foster their survival. Others cite infamous examples like the invasive cane toad in Australia and argue that introducing species to new environments is simply a recipe for disaster.
"What conservationists have been planning for some time is that we might be able to use green habitat corridors so species can jump from place to place quite easily," said Regan Early, a climate change ecologist at the University of Évora, in Portugal. "We're finding it isn't going to be that simple. If we put corridors in place, we are going to have to do a lot of work to help species along."
