Climate scientists tell FRONTLINE that blizzards don’t refute evidence of climate change — in fact, climate change can make blizzards more intense. The first thing people need to understand, they say, is the difference between climate and weather.

Now, new geological dating of that tremendous episode of volcanic activity, by Dr. Blair Schoene from the Department of Geosciences at Princeton University, suggests that the dinosaurs might have been facing a cataclysmic one-two punch of volcanism and cosmic impacts.
Jeroen Tromp, the Blair Professor of Geology and professor of geosciences and applied and computational mathematics, is part of a group to receive 50 million processor hours to start a new project called "Global Adjoint Tomography."
A team of scientists led by the University of Toronto’s Barbara Sherwood Lollar, Chris Ballentine of Oxford University, and Tulis Onstott at Princeton University, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth’s surface in rock fractures in Canada, South Africa and Scandinavia. The study, published in "Nature" on December 18, includes data from 19 different mine sites that were explored.
A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University.
At the start of the 1980s, the question of what forced dinosaurs and huge numbers of other creatures to become extinct 65 million years ago was still a mystery.... “We can now say with confidence,” says Blair Schoene, a Princeton geologist and lead author of the paper, “that the eruptions started 250,000 years before the extinction event, and lasted for a total of 750,000 years.”
Online this week in Science (http://scim.ag/BSchoene), volcanism gets a big boost, and so does one of the most contentious figures in the debate, Princeton University paleontologist Gerta Keller. In the paper, Schoene, Keller, and colleagues report precise dates for the main phase of Deccan volcanism.
Hollister added, in reference to the controversy surrounding planned, postponed and completed seismic studies off the New Jersey coast this past summer, “We monitored marine life very closely (during ACCRETE in 1994) and found no damage had been done.”
