Wildlife collapse related to climate change could happen suddenly

A number of daily newspapers and news sources from across the world are citing an article from Nature, which predicts that the collapse of wildlife species could happen abruptly, rather than gradually.  These include:

The Guardian: https://www.theguardian.com/environment/2020/apr/08/wildlife…

BBC; Reuters; msn etc

The original Nature article is here:

https://www.nature.com/articles/s41586-020-2189-9 and is entitled:

The projected timing of abrupt ecological disruption from climate change,

with authors, Christopher H. Trisos, Cory Merow and Alex L. Pigot in Nature published 8th April 2020.

However, here is a more simply worded analysis from msn:

“Climate change could result in a more abrupt collapse of many animal species than previously thought, starting in the next decade if greenhouse gas emissions are not reduced, according to a study published this month in Nature.

The study predicted that large swaths of ecosystems would falter in waves, creating sudden die-offs that would be catastrophic not only for wildlife, but for the humans who depend on it.

“For a long time things can seem OK and then suddenly they’re not,” said Alex L. Pigot, a scientist at University College London and one of the study’s authors. “Then, it’s too late to do anything about it because you’ve already fallen over this cliff edge.”

The latest research adds to an already bleak picture for the world’s wildlife unless urgent action is taken to preserve habitats and limit climate change. More than a million plant and animal species are at risk of extinction because of the myriad ways humans are changing the earth by farming, fishing, logging, mining, poaching and burning fossil fuels.

The study looked at more than 30,000 species on land and in water to predict how soon climate change would affect population levels and whether those levels would change gradually or suddenly. To answer these questions, the authors determined the hottest temperature that a species is known to have withstood, and then predicted when that temperature would be surpassed around the world under different emissions scenarios.

When they examined the projections, the researchers were surprised that sudden collapses appeared across almost all species — fish, reptiles, amphibians, birds and mammals — and across almost all regions.”
