Animals and plants are shifting their natural home ranges towards the cooler poles three times faster than scientists previously thought. In the largest study of its kind to date, researchers looked at the effects of temperature on over 2,000 species.

"Dr Thomas. Take the polar bear, it does most of its hunting off the ice, and that ice is melting - this July was the lowest ever recorded Arctic ice cover - it has nowhere to go."

The part about the polar bears may or may not be true, but July ice being the lowest ever recorded. That is an outright lie! Yes ice is low, but not as low as it was in 2007. It may get that low before it begins to refreeze, but it isn't there yet.

When people like Thomas make completely false statements like that it tends to discredit the entire findings even though many of them may be absolutely true. How sad that people try to drive home their perception of the world by lying.

There are so many conflicting stories that I am struggling to see what the truth really is, a cynical person might think that this is the intention. All I know for sure if that summers (in the UK) are generally warmer and dryer than when I was a child and that last year we had the coldest winter I can ever remember.

Our fellow travelers on Spaceship Earth are much smarter than we think! I read not too long ago how tigers are finding new habitats, up in the mountains, far from us vicious little humans.

Well, how d'you think they survived the freezeout and hotspot fluctuations of the past? It's recorded in the tree rings and religious histories that we've had cold and hot periods in the past and the animals just come back when the climate steadies again. The animals (well, maybe except for sheep and some humans) have the common sense to move to where they'll survive, and the plants ride the winds, animal fur, or animal digestion to follow.

Minor, brief variations do not impact overall trend. "After a period of slow melt from late July through early August, Arctic ice extent is again declining at a brisk pace, but remains higher than for 2007, the record low year. Data also indicate continued thinning of the ice. With about a month left in the sea ice melt season, the amount of further ice loss will depend mostly on weather patterns. As of August 14, 2011, Arctic sea ice extent was 5.56 million square kilometers (2.15 million square miles), 2.11 million square kilometers (815,000 square miles) below the 1979 to 2000 average for that day, and 220,000 square kilometers (84,900 square miles) above the extent on that day in 2007."

Ice melt in early July in fact was fairly dramatically high. The melt rate did slow in late July, but that does not contradict the overall trend discussed by Chris Thomas.

i was in Nova Scotia this summer and it looks like European garden spiders and Rose Beetles have already moved up from Maine. go figure.

The bottom line is that we need to stop polluting and damaging the earth now before the changes become permanent and we can't go back to they way it was.

I'm about ready to shift myself closer to the north pole! This summer was KILLER! The heatwave was unbearable! So if this is what we have in store for us in the future, I'm outta here! I can't blame plants and animals for wanting to do the same. It's all about survival!

noted, just remember some animals already have nowhere to go and soon many others maybe in that category! there is no other planet for life, lets sve the one we have....

If only the climate change deniers were as smart and the animals and birds. Unfortunately, they seem determined not to listen until its too late. Shame on them.

High altitiude species like picas and wolverines have nowhere else to go. The thick coats that help pika survive winter can roast them if temperatures rise above 77 degrees Fahrenheit for as little as six hours.
The Fish and Wildlife Service has rejected a bid to extend endangered species protection to a rabbit-like creature that environmentalists say could be pushed to extinction by rising temperatures.
"Listing the pika would have forced the Obama administration to take a hard look at climate change, and a very important part of that is bringing the Endangered Species Act tool kit to the fight against global warming."
