Loss of sea ice will eventually lead to decrease in global temperature variability

FRISCO — Climate scientists from the UK say their latest study paints a nuanced picture of global temperature variability, outlining recent geographical shifts and projecting an overall long-term decrease in variability as global temperatures rise.

“Fluctuations in annual average temperatures have shown very substantial geographical alteration in recent decades. However, to our surprise, when considered across the globe, total variability has been relatively stable,” said
lead author Dr. Chris Huntingford, with the Centre for Ecology & Hydrology (a joint program of the University of East Anglia and the University of Exeter).

Yearly temperature variability has increased across large parts of Europe and North America in recent decades, but has decreased or remained stable in other regions, according to the study published July 24 in Nature. Continue reading
