Located a few miles from the northern city of Saint Louis, the village was swept away by the rise in sea level, caused by global warming and the opening of an artificial canal, according to a report published in 2008 by the United Nations Agency for Human Settlement in Africa's director Alioune Badiane Photograph: SEYLLOU/AFP/Getty Images

A great grey owl struggles in windy conditions in Algonquin provincial park in Ontario, Canada. Wildlife photographer Megan Lorenz captured the images last month: 'I left early and found the owl within 10 minutes of looking. It was raining practically all day and very windy but, despite this, I spent a few hours with the owl who looked very wet and unhappy. The wind picked up even more and a few minutes after I started taking photos, it was obvious he was having problems. He was being blown all over the place and his talons were digging in desperately trying to keep his balance' Photograph: Megan Lorenz /Rex Features

A pearl-bordered fritillary. Butterflies are emerging weeks later than usual as a result of the cold spring, conservationists have said.

A green tree frog (Hyla cinerea) sits on the lip of a pitcher plant in a bog in Cherokee County, Alabama. A new study from the US Geological Survey shows just how fast amphibians are disappearing from ponds and creeks across the United States.

An unprecedented stocktake of UK wildlife has revealed that most species are struggling and that one in three have halved in number in the past half century.
