Butterflies Reacting to Global Warming – New Study
Friday, 19 March 2010
A new University of Melbourne led study has concluded that butterflies are changing their lifestyles and living patterns because of global warming. The study noted that butterflies are emerging 10 days earlier than they did just 65 years ago, a change that corresponds with rising temperatures and earlier springs. The earlier to rise butterflies in the Melbourne area have been casually linked to the measured rise in temperatures of 0.14°C per decade in Melbourne, and the warming has been shown to be human-induced (anthropogenic). Another recent study also has found that mountain butterflies in the Sierra Nevada Mountains of California are moving up in elevation to flee from warmer temperatures. A big reason why scientists are extrapolating conclusions from the lives and habits of butterflies is because we have always looked at butterflies. Their beauty and elegance capture the attention of people, and therefore the records that have been kept regarding their habits have been very detailed for a long time. These changes in butterflies may seem small, but they are a great indicator of the larger changes going on in the world. Please do your part to reduce your own carbon footprint.
