Weather bureau denies political pressure

The Bureau of Meteorology has denied it is under political pressure from the federal government to play down the impact of climate change.

Director of Meteorology Rob Vertessy says there's no "strategic attempt" to diminish the bureau's work on climate change.

There had been a restructure within the bureau but although climate divisions had been renamed, there had been "no material change at all" in the architecture of climate change within the bureau, Dr Vertessy told a Senate estimates hearing in Canberra on Monday.
