Paris (AFP) - Global warming will cause "catastrophic" biodiversity loss across the world if greenhouse gas emissions aren't curbed, with some ecosystems liable to collapse as soon as 2030, according to new research into where and when die-offs may occur.
Earth has never in human history warmed so quickly or uniformly as currently, but a variety of factors affect temperatures in individual regions, with significant seasonal and geographic variation.
Scientists predict that at the current level of manmade carbon emissions, Earth is on course to heat up to four degrees Celsius by 2100.
Instead of looking at global trends, researchers in Britain, the United States and South Africa looked at more than 150 years of climate data and cross-referenced that with the spread of more than 30,000 species of birds, mammals, reptiles and fish.
They then divided the globe into 100 square kilometre (39 square mile) segments, and modelled the temperature trends and effects this would have on wildlife in a given area.
Alex Pigot, from University College London's Centre for Biodiversity and Environment, said that the models showed that animal populations were liable to collapse once they cross a temperature "horizon" -- being exposed to heat they're not evolved to handle.
The models change dramatically according to each emissions pathway.
For example, at 4C of warming 15 percent of all animals could see extreme heat that could cause "irreversible damage" to regional ecosystems.
But at 2C of warming -- the cap aimed for in the Paris climate agreement -- that figure dropped to two percent, according to the models.

Is that from one of them there kom-puter models?
I think I’m confused. Isn’t the Sun loosing energy over time? Since we get our heat from the Sun, seems more likely for us to freeze to death.
And there ya have it!
More proof of Global Warming!
Good point, Newbomb.
MODELING will become a laughing point.
