Had it hit anywhere else....

The scientists now find the asteroid that wiped out the dinosaurs happened to hit an unlucky spot — had it landed in about 87 percent of anywhere else on Earth, the mass extinction might not have occurred. "The probability of the mass extinction occurring was only 13 percent," said study lead author Kunio Kaiho, a geochemist at Tohoku University in Sendai, Japan.
The scientists ran computer models simulating the amount of soot that asteroid impacts would have generated depending on the amount of hydrocarbons in the ground. They next estimated the climate effects caused by these different impact scenarios.
The researchers calculated the level of climate change needed to cause a mass extinction was a 14.4 to 18 degrees Fahrenheit (8 to 10 degrees Celsius) drop in global average surface air temperatures. This would involve an asteroid impact sending 385 million tons (350 million metric tons) of soot into the stratosphere.
The scientists found that a mass extinction would have occurred from the impact only if it had hit 13 percent of the surface of the Earth, including both land and oceans. "If the asteroid had hit a low- to medium-level hydrocarbon area on Earth, occupying approximately 87 percent of the Earth's surface, mass extinction could not have occurred," Kaiho told Live Science.
The scientists are also analyzing the level of climate change "caused by large volcanic eruptions that may have contributed to other mass extinctions," Kaiho said. "It is hoped that the results will lead to further understanding of the processes behind those mass extinctions."

Same computer models they use to back up Global Warming Myths.
Had it hit anywhere else....
So, just where did it hit if they know so much? Or, are they guessing again?
good thing they are extinct...
Nana is soft and chewy...
:)
Of course they’re guessing.
It’s total supposition wrapped up in a veneer of pseudo-scientific frou-frou.
Hmmmm.....
Grab them by the nose and kick them in the butt as Patton said in the movie.
Like I always say, they had an army of T Rexes to save them but the best they could muster was small arms.
Alligators, Sea Turtles, Parrots, honeybees living in and around the Gulf of Mexico survived at ground zero while Dinosaurs around the world went extinct.
Suuurrreee, sounds believable
The Chicxulub crater on the Yucatán peninsula of Mexico. Try to keep up.
My thoughts exactly! How do they know what the hydrocarbon of the earth was BEFORE the event? The impact likely liquefied the earths crust in a certain area and superheated and ignited the oxygen in the atmosphere.
They have no idea what they are talking about and can speculate at best. Note that EVERYTHING didn't die. BUT everything needs sunlight and vegetation. I'm sure if they can get more money they can come up with other interesting questions to answer and problems to solve.
A lot of meteors are carbonaceous chondrites. A HUGE lump of coal.
I often thought about what it would be like had the Buffalo been herds of the 1700s been preserved. Can you imaging a 15 million head heard 50 miles long and 20 miles wide crossing I-80?
The planet’s gravity had to be about a third of what it is today for the dinosaurs to live. In today’s gravity they would all collapse and die. No land animal can be larger than an elephant. So, if geological dating is correct (a big “if”), then the Earth’s gravity increased significantly sometime around 65M years ago, and then again when the giant mammels disappeared.
Well, as Enrico Fermi said to Robert Oppenheimer during the Manhattan Project that ended WWII, “This is superb physics”.
Thus, certain things do get done. And we do know a little about a lot.
The GOOD LORD works in mysterious ways.
OOWWWWWW, MY BALLS!
