Climate risk to 1 in 6 species 1 May 2015

One in six species on the planet could face extinction if nothing is done to tackle climate change, analysis suggests

If carbon emissions continue on their current path – and temperatures rise by 4 degrees – 16% of animals and plants will be lost, according to a review of evidence.

The study, published in Science, shows risks are highest in South America, Australia and New Zealand.

Previous estimates range from 0 to 54%.

Dr Mark Urban of the University of Connecticut, US, analysed data from 131 scientific studies on the risk of extinction from climate change.

He found that the rate of biodiversity loss is likely to speed up with each degree Celsius rise in temperature.

If future temperatures rise by 2 degrees compared with pre–industrial times, global extinction risk will rise from 2.8% today to 5.2%.

But under the scenario where global warming continues on its current path, 16% of species (one in six) face extinction.

“If the world does not come together and control greenhouse gas emissions and we allow the Earth to warm considerably we will face a potential loss of one in six species,” said Dr Urban.

“Many species will be able to shift their ranges and keep up with climate change whereas others will not either because their habitat has disappeared or because they can’t reach their habitat anymore.”
