And what their new model found was that as the Arctic sea ice retreats, the atmospheric waves have warmed the polar stratosphere in ways that have been amplified by the behaviour of the ozone layer.

“Our study shows that the changes in the jet stream are at least partly due to the loss of Arctic sea ice. If the ice cover continues to dwindle, we believe that both the frequency and intensity of ...

It's been a hot July. Wildfires in Greece killed at least 83, Sweden is desperately fighting fires above the Arctic circle, heat waves have struck everywhere from the U.K. to Siberia, and at least ...

For about two decades, the jet stream – a powerful band of westerly winds – was observed to have a wavier flow, which coincided with greater Arctic warming through climate change. These waves have ...

We can forecast fairly well what the jet stream will do in the coming days, but doing the same for a future climate scenario is much more complex and requires more data and research.

The “wavier” jet stream can lead to colder weather in the UK and the on continental Europe. But scientists now think the change in wind patterns is not caused by the Arctic.

Extreme cold weather being caused by the jet stream is not a result of Arctic warming, research suggests. Past studies have indicated the warming Arctic region causes a wavier jet stream – which ...
