Situation Normal - Worse Than Expected
...the change in weather may be due to the shrinking of the sea ice cap in the Arctic. Ice cover there has been disappearing at a striking rate and is currently at its lowest recorded level for this time of year. Less and less solar radiation is being reflected back into space as a result, and the atmosphere heats up. But how such a phenomenon could affect the weather over Britain is unclear.
Meteorologist Tim Woollings, of Reading University, said: "Climate models are starting to show some agreement that jet streams will shift slight closer to the poles in response to increases in greenhouse gases."
Such a trend could bring more settled, dry hot weather systems to Britain, though predictions are unclear. "There is still considerable disagreement between different models," Woollings added. "The hot weather we had this year arose because the jet stream was deflected south. Last year, it occurred because the stream was deflected north. So it is still very difficult to predict what will happen."
However, Woollings was sure that climate change would continue to have an influence. "One thing we can say is that even if the statistics of weather regimes do not change, we may feel the impact of some of them more strongly.
So even though Arctic sea ice in the spring is within a smidgen of what it has been "since records began". And one year it is warm because the jet streams go north, and next year because they go south. And the statistics may not change... We are all going to die.
