Climate Change And Butterflies
A project has looked at the temperatures in cities and also the first of this butterfly to be seen each spring from the 1940s onwards.
What this has shown is that for each decade the butterflies have first emerged 1.6 days earlier and so therefore the butterflies are now appearing over 10 days earlier than they did in just the 1940s.
Therefore this would seem to suggest tht there is a link between global warming and the changes in the time when this insect has emerged. And therefore if it can be assumed that there is not anything unique about this insect, then presumably it is the same for insects and for other creatures too such as birds and so forth.
