TORONTO -- Along the border of France and Spain, bumblebees are moving on up.
Researchers tracked bumblebees in the Pyrenees mountain range, and found that they are moving to higher latitudes – nearly 130 metres higher than they were in the late 19th century, on average.
Climate change appears to be a key driver of this vertical migration. The Pyrenees have warmed significantly over the past century-plus, leading to changes in where certain plants can be found – and bringing along the bumblebees that rely on those plants.
In the video at the top of this article, Â鶹´«Ã½ Science and Technology Specialist Dan Riskin explains why scientists are concerned the bumblebees' great leap upward could ultimately cause them to disappear.
