Romney on Climate Change

Mitt Romney has a difficult relationship with the thorny issue of climate change, with attacks on his flippant remarks about rising sea levels. But the starkest flip-flop he has made involves the effect of human activity on climate change. The change of heart is starkly illustrated by two quotes from Romney, made just a year apart. The first featured in his 2010 book “No apology”, where he says “I believe that climate change is occurring…I also believe that human activity is a contributing factor”. A year later, speaking at the Consol Energy Center in Pittsburgh, Pennsylvania, he said “My view is that we don’t know what’s causing climate change on this planet”. So, what’s it to be Mitt? Or does it depend on which side is more powerful at the time?
