According to calculations done by a Japanese climate expert, the next major mass extinction won't happen until the year 2500 AD at the earliest.
Heatwaves in recent years are a result of climate change that has been accelerated by human activity over the past few centuries. Extreme heat to extreme cold and back again cycles occur on our home planet. There have been instances where a huge number of species have vanished in a relatively short amount of time as the cycle proceeds from the peak of extreme cold to the peak of excessive heat. Events like these are known as mass extinctions.
In case you didn't know, over the previous 540 million years, the Earth has experienced five such major extinction events. 95 percent of the world's species perished in the greatest of these episodes, whi...
