Donald Trump says ‘nobody really knows’ if climate change is real

Despite overwhelming scientific consensus, President-elect Donald Trump claimed “nobody really knows” whether climate change is real when confronted Sunday with his inconsistent statements on the issue. Fox News anchor Chris Wallace asked Trump where he stands on the environment, given that he’s variously called climate change a hoax and said he has an open mind about the issue. The vast majority of scientific organizations have said the scientific evidence for the climate system’s warming is unequivocal.
