I asked for scientific evidence, not a political blogger on a conservative website known for its psuedo science. It appears on his own website, not in a scientific journal. Amigo, Doug L. Hoffman is not a scientist and has never authored a single scientific paper in a single scientific journal. In fact, here is what Wikipedia has to say about him
"businessman, accountant and former congressional candidate. He was the Conservative Party candidate for the U.S. House of Representatives in the 2009 special election for New York's 23rd congressional district. On November 3, 2009, he was defeated by Democratic candidate Bill Owens. Hoffman ran for the same seat in Congress in 2010, but lost the Republican primary and withdrew his candidacy. Hoffman's 2009 campaign received extensive support from the Tea Party movement and gained national attention."
Those aren't scientific credentials, they are political credentials.
His evidence is a hodgepodge of stating the obvious mixed with claims he cannot prove. His citations are laughable. His idea that AGW cannot cause an event similar to the PETM is not proved. Plus its apples and oranges. The huge difference is that the PETM was accompanied by a catastrophic event such as a supervolcano eruption or a large meteor strike. It caused global warming mass extinctions but it was accompanied by a signature spike associated with catastrophic events. However many true scientists are studying the PETM precisely because it offers insights into our current warming situation.
AGW is significant because of the rapid pace of change but no one has ever suggested that it could ever match the immediate changes brought on by a catastrophic event. It is irrelevant. The problems associated with AGW can cause problems enough for us. Sea level rise is the biggest followed by rapidly changing climate patterns.
Well, your link doesn't work so we can't put that quote into context. Jerry Dickens is a geoscientist and a damn good one. The major thrust of his published research involves his studies of how methane also causes global warming. But his 2011 paper studied carbonaceous geologic deposits associated with the PETA. The conclusion of his abstract states:
"We suggest that over ~6 million years, there was a series of short-term climate perturbations, each characterized by massive carbon input and greater continental weathering. The suspected link involves global warming and enhanced seasonality in precipitation. We are evaluating this model further by identifying hyperthermal events in DSDP sites from the Indian Ocean, and assessing whether they are related to carbonate dissolution or siliciclastic dilution."
No debunking of AGW there.
Did you really find that interesting? Geez . . . more psuedo science from the politician's own website. Same pattern . . . stating the obvious, followed by invalid assessments based on guesswork, and conclusions that are irrelevant to the issue.
Cowboy, you're bringing rocks to a gunfight.
