• Earth’s average surface temperature and loss of biodiversity have a linear relation
• The biggest mass extinction happened 250 million years ago
• A temperature of 9^oC is needed for a mass extinction event

A Japanese climate scientist has run the numbers for the next big mass extinction and does not expect us to reach there till the year 2500 AD, ScienceAlert reported.
