Yes, Folks, it's All Global Warming's Fault! Yes, The reason your car won't start or your coffee doesn't taste the same or your news paper isn't at your front door, Yes you all know it's because of Global Warming!
Well now they've found that for the past 40 years, bee's Tongues have Shrunk,,, YES,, didn't you know that 40 years ago, back in what 1985, they measure bee's tongues? YES! Just so they could ckech to see if they'd Shrink, and Guess What,,,, They DID and it's Global Warming's Fault!
OH,,, but we're not done yet,,,, because the temperature is so much more higher than is was in the 60's they say. I thought in the 70's we were going to be in an other Ice Age!
All Hail Honey Bee's and their Global Warming Changing Tongues!

Global warming and evolution are reshaping the bodies of some American bumblebees, a new study finds. The tongues of two Rocky Mountains species of bumblebees are about one-quarter shorter than they were 40 years ago, evolving that way because climate change altered the buffet of wildflowers they normally feed from, according to a study published Thursday in the journal Science.
In one of these species, the tongue had been half the size of the bee's body — the equivalent of a human tongue going down to the waist. But because the flowers where the long tongue is required have dwindled, the bees didn't need that much tongue. Keeping long tongues requires bees use more energy, so the bees evolved a shorter tongue that allows them to sample a wider variety of flowers, said study lead author Nicole Miller-Struttmann at the State University of New York, Old Westbury.

While biologists have tracked how global warming has altered the developmental, migration, timing and other behavior in plants and animals, what makes this study unusual is the physical changes in the bees, said study co-author Candace Galen at the University of Missouri.
"It speaks to the magnitude of the change of the climate that it's affecting the evolution of the organisms," Galen said. "It's a beautiful demonstration of adaptive evolution."
Because these were so isolated and so high — more than 10,000 feet — pesticides and pathogens, often blamed for bee declines, weren't a problem, the scientists said. Something else had to be an issue.
The team of biologists studied the bees on three isolated mountaintops in the Rockies, where they had been the most dominant species around. Not so much anymore, Miller-Struttmann said. The longer tongued of the two bees, the golden belted bumblebee, shrank from 50 percent of all the bees to 20 percent, she said.

They compared the bees to those of 40 years ago or more and found the tongues dramatically shorter. They also found that the temperature in the area had warmed by about 3.6 degrees since the 1960s and the type and amount of flowers had changed.
