Relationships end for myriad reasons – but climate change isn’t usually one of them. For black-browed albatrosses, however, rising ocean temperatures are driving a divorce boom, raising questions about how many other species’ lives are being unexpectedly disrupted by global warming.

Researchers found that as the seas warmed around the birds’ Falkland Islands habitats, monogamous albatross couples – who often stay together throughout their 70-year lifespans – are more likely to split up and find new partners. It seems as if the birds are blaming each other for the consequences of warmer waters, including longer journeys to find food and less free time for taking care of chicks. Even if albatrosses couple up again, they could be less successful at raising chicks with their new partners, possibly threatening albatross populations over time.

Elsewhere, we’ve learnt that plankton and mountains, although at opposite ends of a size chart, share a surprising link. Two billion years ago, dying plankton populations were compressed into graphite at the bottom of the sea, providing the lubrication necessary to build mountain ranges on land. And, in pandemic news, a series of surveys gives us a better idea of what our ‘new normal’ might look like.

How plankton helped create the Earth’s mountains 2 billion years ago

John Parnell, University of Aberdeen

Mountains can’t be created without lubricant, and 2 billion years ago that lubricant was graphite produced by the carbon broken down from layers of dead plankton on the ocean floor.
