Climate change will bring greater extremes in weather, the Government’s chief scientific adviser has warned as he called for action to deal with global warming. Professor Sir John Beddington says the effects of climate change on the weather are already being felt in the UK.
“In a sense we have moved from the idea of global warming to the idea of climate change, and that is rather important. Temperatures are increasing and there are more changes in our weather,” he said.
Even if effective action is taken now on global warming, he says there will be great climate change over the next 20 to 25 years as a result of past global problems.
“We have serious problems in the world --- in 12 years there will be another billion people on the planet and we have big issues of food security, water security and energy security, and many people will start to be living in cities,” he said. “These are serious problem; climate change is just going to make it worse.”
He said there were some “uncertainties” in the analysis of climate and climate change. “But those uncertainties are completely unimportant in comparison（比较）with a great deal of evidence that shows it is happening in the sort of ways climate models would expect,” he said. “For example, the Arctic is heating up faster than other parts of the world --- this is exactly what the climate scientists are predicting.”
Sir John’s views were made as Britain experienced freezing cold weather and snow, with thousands of homes across the UK without power. England and Wales experienced 10 separate flooding events between April and December last year after widespread drought gave way to the wettest summer in a century, with unusually high rainfall totals and river levels around the country.
