Scientists say appearance of dramatic red or orange snow is likely to become more frequent due to climate change


UAE researchers have revealed new details about how dust is travelling from the Sahara to the Alps to cause snowy pistes and glaciers to turn a dramatic red, pink or orange.


The striking colouration, which happens when the dust causes the growth of microalgae, makes the snow melt more easily and is likely to become more frequent because of climate change.


Scientists at Khalifa University in Abu Dhabi reported that flows of air called atmospheric rivers are closely linked to the transport of dust from the Sahara to as far as northern Europe.


“In our study, we found an increasing trend in atmospheric rivers and associated severe dust transport episodes towards Europe,” said an author of the study, Dr Diana Francis, head of Khalifa University’s Environmental and Geophysical Sciences (ENGEOS) Laboratory.
