Global Warming going to destroy the World

March 27: We all known about the Global Warming and the main reason for the Global Warming is human begins. yes, we are the one, who is destroying the entire world with many kinds of pollution, but we still have time to save the world but no care will care about it.

Earth's worst mass extinction in history - when around 90 per cent of all life was wiped out - may one day repeat itself, scientists have warned.

The Permian-Triassic catastrophe occurred 250 million years ago when rapidly rising levels of carbon dioxide and methane triggered runaway global warming, according to new research.

Researchers said their findings should act as 'an important lesson for humanity' in how we tackle current climate change.

Earth has suffered through five mass extinction events - catastrophes where large swathes of species die out in a short space of time.

But no event was more deadly than the end-Permian, which wiped out 96 per cent of sea life and 70 per cent of life on land.

Researchers have long debated what sparked the extinction event and it is thought that meteor showers and mass volcano eruptions played a role in the deadly event.

Now researchers from Brock University in Ontario have reexamined the trapped gasses in ancient rocks and have found that the extinction event was largely driven by climate change.

They said frequent volcanic eruptions led to large amounts of carbon dioxide being released into the air, which could have caused global temperatures to rise to 11°C (52°F).

The rising temperature led to the melting of permafrost that had locked in the vast amounts of methane.
