Skeptics may have been right on occasion in the past about certain issues, but that doesn't mean that global warming deniers are right today. Most of America's business leaders, the U.S. military, 200 nations around the world, and (confirmed by FactCheck) 98% of scientists who have expressed an opinion - they all agree; the science is settled. According to an email from one of ExxonMobil's own scientists, ExxonMobil became aware of global warming more than 30 years ago. Today, the company publicly acknowledges the risks of climate change. Who denies it? Only the descendants of flat-earthers.
Moderator's Note: There has been global warming and freezing since the creation of the earth. The question is: Is man's activity having a negative impact?
