What to know about Thawing Arctic riverbeds may erode up to 10 times faster than unfrozen ground

Researchers from Simon Fraser University and the University of British Columbia found that thawing Arctic riverbeds can erode up to ten times faster than unfrozen ground. The study, which combined lab simulations and field observations on Devon Island, suggests that climate change is rapidly altering Arctic landscapes and river systems.

What happened

Thawing Arctic riverbeds may erode up to 10 times faster than unfrozen ground Andrew Zinin Chief Editor Sometimes science throws up the unexpected.

Why it matters

When a team of researchers set out to model river erosion in Canada's High Arctic, they did not expect the findings to defy common sense.

Common ground

"We literally expected to see the opposite of what we ended up seeing," says Jonas Eschenfelder, a Ph.D.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
