26 March 2013 – The UK government chief scientific adviser John Beddington has stepped down from his post with calls for more urgency on climate change  and warned there would be more floods and droughts over the next 25 years.

He told the BBC there was unequivocal evidence that climate change was happening and warned that long delays in carbon dioxide levels impacting upon weather patterns, means the next 20 or 30 years will be determined by current activity.

The UK Institution of Chemical Engineers chief executive officer David Brown said this was a world-wide problem and called on the UK government to back the sentiments and to work more closely with industry in climate action.

“Governments and industry must work together to accelerate research and application on a large scale of efficiency improvements, cleaner and renewable energy, including nuclear, and the introduction of new low carbon materials and processes – or future generations will condemn us for our obstinate folly.”
