Volcanism Killed the Dinosaurs
 

Under- and above-water volcanism lead to an ice age

 "It wasn't the impact of an asteroid that killed the dinosaurs 65 million years ago, reports Science Daily of new research from Cardiff University in Wales. "It was a mantle plume, a huge volcanic eruption from deep within Earth's mantle...." "The massive outpouring of lava, ashes, and gas can have significant effects on climate." 

(I agree, I agree, I agree. I think the mantle plume heated the seas. This caused increased evaporation. Then the excess moisture rose into the skies, skies which had  already cooled because of the ash. This lead to massive increases in snowfall, and to an ice age. And that's what I've been saying all along.)

Here's another article on the same subject:

"Volcanic 'flood' linked to extinction"

"A huge outpouring of molten rock 250 million years ago may have been the decisive factor in the deaths of nearly all life forms on the Earth at that time," says a recent article in the journal Science. 

The flood basalts at the Siberian Traps covered around 3.9 million square kilometers, says Marc Reichow, of the University of Leicester, UK., an area much larger than previously believed.

Reichow's studies suggest that the "volcanic flood" was about one mile deep, and covered an area half the size of Australia.

          Question. If the vast majority of volcanic activity takes place under 
          water, wouldn't it seem as if an underwater area several times the size 
          of Australia should have been concurrently covered with a mile-deep 
          layer of lava? 

          And every single one of those millions of kilometers of lava would 
          have been incredibly hot; up to 2,100 degrees Fahrenheit hot. 

          It's not global warming, it's ocean warming, and it's leading us into 
          an ice age. 

          I think the same thing happened at the dinosaur extinction of 65
          million years ago. For anyone familiar with that extinction, you know
          that there was a huge volcanic outpouring at the time known as the
          Deccan Traps. It covered one million square miles of India and the
          surrounding areas under successive layers of basalt up to one-and-a-
          half-miles deep. 

          Note: According to paleontologist Dewey McLean (personal
          communication), a good portion of the Deccan Traps was submarine.
          This would explain why ocean temperatures at the dinosaur extinction
          rose by some 14 to 22F.

Intense volcanic activity linked to dinosaur-era extinctions  

1 Nov 03 - Peter Ward, a University of Washington paleontologist, thinks intense volcanic activity may have caused widespread extinctions 250 million years ago at the end-Permian, and about 200 million years ago at the end-Triassic.
