Animals are migrating further than previously thought, and it’s all because of global warming.
Birds, mammals, insects, spiders and reptiles from North America and Europe are found to be traveling the greatest distance in areas of high global warming. Those that can’t move or adapt are at greater risk.
Animals are moving to higher levels of altitude and away from the equator, meaning global warming is having a stronger effect on animals than previously thought.
This new information could aid in a model for species migration.

The Comma Butterfly is featured in the press release with the claim that "Meanwhile, the comma butterfly has moved 220 kilometres northwards from central England to Edinburgh, in only two decades."
However the Comma Butterfly has previously been common in Scotland (-see link below). Seems what goes around comes around, and the simple message that "climate change" is responsible is much more complicated.
From the Glasgow and SW Scotland Branch of Butterfly Conservation:

"The Comma is known to have a very dynamic range in the UK. It was known in eastern Scotland in the early-19th century being found as far north as Fife and Alloa, Clackmannanshire in the east but it was absent in western Scotland. After 1850, the Comma was in decline with the last 19th century record being for Denholm, the Borders in 1868."
