A mass extinction which mops out humanity will be underway by the year 2100, scientists have claimed.
By the end of the century, it’s is concerned that so much better carbon will have been added to the oceans that the planet will have overstepped a “threshold of catatastrophe” which leads to the destroyer of our species.
In the past 540 million years countries around the world has abode five such wipeouts- including the demise of the dinosaurs.
The bad took place 252 million years ago and is known as the Great Dying .
This disaster killed off more than 95 per cent of the members of naval life when the seas unexpectedly became more acidic.
Now geophysicist Professor Daniel Rothman says we are seeing a disturbing parallel today- this time because of man-made global warming.
He came up with a simple mathematic formula which predict that the oceans will soon hold so much carbon that a mass extinction is inescapable.
It demonstrated the crucial additional quantity expected is about 310 gigatons- which is the best client scenario projected by the Intergovernmental Panel on Climate change issues( IPCC ).
And it’s well below the worst of more than 500 gigatons – which would far exceed the line.
In all situations, such studies found by the end of the century the carbon cycle will either be close to – or well beyond – the threshold for catastrophe.
Although mass extinction won’t soon follow around the turn of the century the world are likely to have tip-off into “unknown territory”.
Professor Rothman, of the Massachusetts Institute of Technology, says it would make some time – about 10,000 times – for such environmental accidents to play out.
He said: “This is not saying accident arises the next day.
“It’s saying – if left unchecked – the carbon cycle would move into a realm which would be no longer stable and would behave in a way that would be difficult to predict.
“In the past this type of behaviour is consistent with mass extinction.”
In the modern age CO2 releases have risen steadily since the 19 th century but deciphering whether it is possible to lead to mass extinction has been challenging.
Humans have exhaled 1,540 billion tonnes of CO2 since the industrial coup – equivalent to igniting enough coal to words a square tower 72 paws broad extending 240,000 miles from Earth to the Moon.
Half of these have remained in the flavor causing a rise in positions at least 10 times faster than any known natural multiplication during Earth’s long history.
Most of the other half has dissolved into the ocean – generating acidification.
Will this lead to the ruin of humanity?
Your grandchildren will probably catch out, unless something changes now.
