Summary- The study which focuses on North American rattlesnakes. Researchers find that the habitat will be two to three orders of magnitude greater than the average change over the past 200 millennia. Over the next 90 years at best these species will change more than 100 times faster than they have in the last 320,000 years. The researchers make fact that species have been responding to climate change throughout their history and their past responses which can inform what to expect in the future. Projecting the model into the future the researchers calculate the expected changes in range at the upper and lower extremes of warming. Climate change between 1.1 degree and 6.4 degree Celsius. The researchers then calculate that rattlesnake’s ranges have moved about an average of 2.3 meters a year in the past 320,000 years. Also that their tolerances to climate have evolved about 100 to 1000 times slower.

Critique- I think it is cool how the rattlesnakes have moved 2.3 meters a year in the past 320,000 years. You can see now that the climate is changing a lot if the rattlesnakes have moved that much in the last 320,000 years. The climate which has changed between 1.1 and 6.4 degree Celsius will change the temperature a lot if it was per year even to per 5 years.

Impact- This will affect not only rattlesnakes but it will also affect other animals out there. The impact will show that researchers can look where most of the animals will be from calculating from the past to now. So researchers can see where the other animals will be in the future.
