M WATSON, obviously a climate change sceptic, complains that figures regarding air pollution lack details as to what measurements were done, where they were done and what instruments were used (HAS, Oct 16).

He then uses the same approach he has complained about with a claim that scientific work exists to show that warming, ongoing since 1850, may soon cease.

In response I am entitled to ask where can I read the report, is it in a reputable peer reviewed journal, who are the scientists involved and is the work sponsored by those with vested interest in the results?
