"We have a moral dilemma: How do we protect the health of the poorest people in the world and allow them to develop," Maslin said.
"There are so many public health issues associated with global warming that certainly, once it becomes a significant problem, it will be the most significant public health problem at that point in time," Donnelly said.
"This is a problem that affects the entire planet, and the longer it takes 'us,' the people on this planet, to take action, the more difficult it will be to resolve the problem," Donnelly said. "We urgently need to take at least minimal action to try to reduce emissions and move toward taking more significant action to reduce global warming."
The U.S. Environmental Protection Agency has more on global warming.
