Butterfly Lessons

I didn't know what to expect from this article before I started reading it.  After the first couple paragraphs, I was starting to think this paper was going to be a hard read. Then it got interesting. With all the discussions going on about global warming and climate change, this paper is relevant to today's talks. Personally I believe in the fact the Earth is getting warmer each year because of different reasons with the biggest reason being the increase in CO2 concentration. This paper talks about how this change in climate can be observed by studying various organisms. The major factor that is studied is the change in the range of their habitat. Plants and animals that couldn't survive cold and harsh winters can now live further north than they could have in previous years. This is all because of the warming of our planet due to our civilization becoming more and more dependent on fossil fuels. There are some arguments saying that this is just part of a natural cycle but its hard to argue against the point that humans have definitely sped that process up. This paper opened my eyes to the fact that there are gauges out there that can measure climate change in the form of various organisms. If nothing is done to slow this climate change we are speeding up, some of these organisms might run out of area that they can call home.
