AMS president and Georgia Athletic Association Professor of geography Marshall Shepherd is quoted in CNN's rundown of the top science stories of 2013. On climate change:
Scientists are also hoping to help our own species understand the perils associated with climate change. The phenomenon raises the likelihood of severe weather events and is predicted to damage agriculture, forestry, ecosystems and human health.
A key symbolic moment was when the average concentration of atmospheric carbon dioxide hit 400 parts per million in Mauna Loa, Hawaii, in May. Such levels haven't been seen in about 3 million years, said J. Marshall Shepherd at the University of Georgia.
Happy New Year. Let's resolve to do our part as individuals to lower this crucial indicator - the atmospheric carbon inventory. You can do it - you only have to decide to. Thanks to Dr. Marshall for continuing to be an important voice on this issue.
