Scientist Says:"Climate Change Killed Dinosaurs"

Was it long-term climate change, rather than a rogue asteroid, that killed off the dinosaurs?
That's the conclusion of German paleontologist Micael Prauss, who studied 65-million-yar-old fossils drilled out of the earth in the Brazos River area of Texas and argues that radical changes to the flora and fauna of the era began long before arrival of the massive space rock widely associated with one of the largest mass extinctions in the history of the planet.
The impact, at what is now Chicxulub, Mexico, in the past 30 years has become the primary suspect in the death of the dinosaurs, it was the subfect of an acticle in the journal "Science" earlier this month in which 41 scientists from around the world argured that a wealth of global data show the extinctions began at the same time that the asteroid's crash sent debris across the atmosphere and blocked out the sun for years. A German scientist refutes the widely accepted theory that an asteroid led to dinosaurs extinction, saying long-term climate change was to blame instead.
The resulting chronic stress, to which of course the meteorite impact was a contributing factor, is likely to have been fundamental to the crisis in the biosphere and finally the mass extinction, Prauss said. Those events include the massive , years-long volcanic activity in what is now the Deccan Plateau of India, and which, like Chicxulub asteroid impact, is conventionally used by paleontologists to separate the cretaceous period from the Paleogene period.The Cretaceous, with a relatively warm climate at high sea levels , was the last era of the dinosaurs and the large marine reptiles that lived at the same time.The actual impact took place well before the geochemically and micropaleontologically defined Cretaceous Paleogene boundary, he said.In support of his theories , Prauss cites his analysis of samples taken from drill cores and rock sections dating to the Cretaceous-Paleogene boundary near Brazos, which is about 620 miles from the Chicxulub crater.
Prauss said the fern spike began well before the Paleogene period began, and that the Cretaceous period again, and that the Cretaceous-Paleogene boundary - and the asteroid impact - marked only the peak of a trend that began millions of years earlier. In the light of new data, both of these points have to be refuted, Prauss said. Still, it's almost impossible to change the skeptics minds, Tamara Goldin said. But we hope to we can communicate to the sicentific community and the public that this impact-induced environmental catastrophe did happen.
My spin: What are the scientists telling us....Earthquakes are erupting around the world and one is more destructive than the last one....take a look at all the earthqurakes...Haiti and Chile...they was very powerful....climate change is here folks, it's time for us to take our heads out of the sand and help ourselves.
