Climate change-ravaged rodent listed as extinct
It was described in 2016 as the first mammalian extinction caused by human-induced climate change. Now the eradication of the Bramble Cay melomys has been officially recognised by Australia, its only known home. The rodent lived solely on a tiny sand island in the Torres Strait, near the coast of Papua New Guinea. The species has not been seen since 2009. Scientists say there is a chance that an identical or similar species could yet be discovered in Papua New Guinea…
A state government report said it was almost certainly caused by “ocean inundation of the low-lying cay, very likely on multiple occasions, during the last decade, causing dramatic habitat loss and perhaps also direct mortality of individuals”. It added: “Significantly, this probably represents the first recorded mammalian extinction due to anthropogenic climate change.”
Luckily, a BBC wildlife camera crew was on hand to record the tragedy. They watched aghast as the water crept up on the little blighters while they paddled innocently on this 5 hectare sandbank. At three millimetres a year, they stood no chance, and the direct mortality of individuals was the inevitable result.
Just don’t tell Greta.
