Solar dimming can trigger freezing winters: study
A cyclical drop in the sun’s radiation can trigger unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for blizzards.
Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on the surface reaches a peak then falls. But pinning down a clear link to weather has proved harder.
“Our research confirms the observed link between solar variability and regional winter climate,” lead author Sarah Ineson of the UK Met Office told Reuters in an email. The study was published in the journal Nature Geoscience on Monday. (Reuters)
