How an experimental Minnesota forest is helping predict what could happen in different climate change scenarios

In Northern Minnesota, scientists work at the Marcell Experimental Forest. David Weston, a senior scientist at Oak Ridge National Laboratory, along with more than 100 other researchers, comes to the forest to study how different degrees of global warming might impact the world's northern forests. 

"It's giving us some idea of how far we can push the system and how resilient the system might be. It's absolutely amazing to have a future scenario that you can measure right now today," Weston told CBS News' senior national and environmental correspondent Ben Tracy.

The group pumps heat and carbon dioxide into chambers with the temperature simulations ranging from no warming all the way up to 9 degrees Celsius – or about 48 degrees Fahrenheit.
