Dr Wratt, who is also on the steering group of the intergovernmental panel on climate change, said arguments denying global warming often featured in the media, the most recent claiming temperatures were falling rather than rising.

All the data showed while temperatures variations were numerous, there was a continual upward trend, meaning those arguments could be "robustly rebutted", he said.

Research showed the climate was changing because of greenhouse gas emissions and would do so increasingly unless something was done.
