Iceberg Scientists who advocate renewable energy and think climate change is a real issue have been described as more credible than their sceptical peers.

William Anderegg at Stanford University carried out a study of those experts who have written papers on the issue of climate change.

The research, published in Proceedings of the National Academy of Sciences, showed that those who believe man is contributing to changing temperature patterns across the world have published more papers on the issue than those who deny the problem.

Mr Anderegg concluded that this gives sceptics less credibility than those who regard climate change as a reality, since they are less productive and not actual specialists in this field.

However, Lorraine Whitmarsh of Cardiff University has stated that the survey "deliberately" selected scientists who have published high-profile public documents.

Speaking to PhysicsWorld.com, she said this means behind the scenes researchers with less extreme views may have been excluded.

Judith Curry of the Georgia Institute of Technology added that the research was "completely unconvincing".
