A study published in the June 10 issue of the journal Nature clearly demonstrates changes in species ranges as butterflies shift north to track a changing climate as the planet warms up.
Camille Parmesan, Ph D., and her co-investigators found that out of 57 species studied in Europe and North Africa, 35 of which there were data for both the northern and southern range boundaries, two thirds had shifted northward. Most of the remaining one third remained stable.
“This puts the nail in the coffin,” said Parmesan of the results. “It’s black and white.”
