Climate scientists are like an exotic tribe – fascinating, sometimes hard to understand and rarely visited. The editor of a science journal warned me that I would find little to interest mainstream readers – the boffins would agree on pretty much everything. The debate, she implied, was over. She was wrong.
While climate scientists agree the world is warming due to man's activities, there are still large areas of conflict, notably over how certain we can be about the predictions.
Assembling any top 10 is fraught with difficulties. Assemble one for climate scientists and the problem is exacerbated by the complexity of their research and the range of specialist fields that make up a broad science.
