Global environmental challenges
from Summit Notebook:
Scientists may face an uphill battle in trying to warn the world about the looming perils of global warming, but one of Britain's top academics wouldn't trade places with the politicians tasked with negotiating a new global treaty to cut greenhouse gas emissions.
"Although the science (of climate change) is difficult and still uncertain, it's a doddle compared to the politics," said Martin Rees, president of the Royal Society, Britain's science academy.
Thousands of international delegates will convene at UN climate talks in Copenhagen in December. All early indications suggest those talks, seen as critical to agreeing a successor to the Kyoto Protocol after it expires in 2012, will be anything but a cake walk.
That said, Rees thinks UK policymakers have done a good job so far.
"We must give (the UK) government credit for its leadership in this area, going back to the Gleneagles G8 summit in 2005 when climate change was pushed up the agenda," Rees said at the Reuters Climate and Alternative Energy Summit this week.
