The probability of mass extinction
occurring after an asteroid that could hit a random location on the Earth's surface was approximately 13 percent when the Chicxulub-scale asteroid hit the Earth.
As scientists have noted, a mass extinction
was achieved when the natural carbon cycle failed to compensate for such discarding.
But is the claim that we are undergoing mass extinction
event to rank alongside the five major wipeouts of the last half-billion years justifiable?
The preferential removal of the largest animals from the modern oceans, unprecedented in the history of animal life, may disrupt ecosystems for millions of years even at levels of taxonomic loss far below those of previous mass extinctions
," the authors wrote.
Scientists have long suspected that an ocean acidification event occurred during the greatest mass extinction
of all time, but direct evidence has been lacking until now," said Matthew Clarkson, of the University of Edinburgh's School of GeoSciences, who coordinated the study.
Millions of years from now, the planet will be inhabited only by the descendants of those creatures that survive this new mass extinction
It probably indicates a significant mass extinction
of the conodont fauna in the middle Telychian.
Alien forces aren't always at play in mass extinctions
Lead author Yadong Sun, who is based in Leeds while completing a joint PhD in geology, says: "Global warming has long been linked to the end-Permian mass extinction
, but this study is the first to show extreme temperatures kept life from re-starting in Equatorial latitudes for millions of years.
FOR five million years after the worst mass extinction
in Earth history, much of the planet was simply too hot for anything to survive, scientists have learned.
During each so-called mass extinction
, more than three quarters of the existing species died off in the blink of an eye, geologically speaKing
But thanks to overhunting, deforestation, pollution, the spread of non-native species and now climate change, we are likely in the midst of the sixth mass extinction
in the geologic history of the world.
