David, Just wondering were I can find concrete data that supports your statement that species such as polar bears, butterflies, frogs and pine trees are struggling amid the climate changes.

You state that you will take the safe side when it comes to global warming. The U.S. economy can not afford to take the same stance based on faulty, possibly fraudulent data.

If you want to use the better safe than sorry philosophy, I would recommend that you not ride in an automobile (or participate in other everyday task) where the data is indisputable that your life is at an increased risk. I believe that you will quickly find that it is an unacceptable choice for your personal economy.
