Kunio Kaiho, a climate scientist at Tohoku University in Japan, called the date for the next mass extinction. His research was published in Biogeosciences.
Five mass extinctions have occurred over the past 540million years. Often, these extinctions were accompanied by climate changes. Kaiho examined the stability of the Earth’s average temperature and the biodiversity of planet Earth. A pattern emerged: The greater the temperature change, the greater the likelihood of extinction. Global cooling is the most severe form of mass extinction. Temperatures dropped by 7 degrees Celsius. When the temperature rose 9 degrees C, mass extinctions were caused by warming. Kaiho stated.
The average temperature increase in the Earth’s atmosphere is expected to be 4.4 degrees Celsius by the end of this century. Kaiho predicts that Global warming to 9degC won’t occur before at least 2500 in the worst-case scenario.
Scientists claim that the climate is changing faster than ever before due to anthropogenic causes. This could mean that many more species will be extinct by the sixth mass extinction.
” It is possible that more species will die this time around, not because of the rapid rate at which the climate has changed, but because many species have not been able adapt to the changes.
