Butterfly Lessons in Class Post

Kolber makes many observations about how human caused climate change is affecting species worldwide.  She talks about how butterflies in Europe are moving north, a species of frogs in New York are mating ten days earlier because of average temperatures increasing, plants moving further up mountains to areas where it is cooler, etc.  She believes all these changes are happening too quick and is trying to send a message to humans.   She wants human caused climate change to drastically slow down.  This relates very closely to my project.  Levels of water in the Colorado River are dropping very quickly.  Part of this is because of overharvesting water from it, but another part can be blamed on climate change.  Due to warmer temperatures, snow on the Rocky Mountains is melting much earlier than it usually does.  This is reducing the amount of run off; therefore less water is actually making it to the Colorado River.   Some researchers have found that climate change has caused a 10% reduction in flow of the Colorado River, and there is a 25% chance that reservoir storage will be completely depleted by 2057.
