A key federal opposition frontbencher has voiced his scepticism about climate change.

Opposition defence spokesman, and leader of the opposition in the Senate Nick Minchin said there were still doubts on the science used to back up claims about climate change.

"I do think that the claims being made in relation to climate change generally are often very exaggerated," he told ABC Television.
