Scoff-worthy claim from new hockey stick promoter Shaun Marcott: "we can be dead certain [the shells] are recording the temperature we think they're recording"

Today, it's getting a makeover: A study published in Science reconstructs global temperatures further back than ever before—a full 11,300 years. The new analysis finds that the only problem with Mann's hockey stick was that its handle was about 9,000 years too short...the key, said lead author Shaun Marcott of Oregon State University, is that temperatures are shooting through the roof faster than we've ever seen.
...
"There's been a lot of work that's gone into the calibrations, so we can be dead certain [the shells] are recording the temperature we think they're recording," he said.
...
Mann himself, who literally wrote the book on attacks on climate scientists, said in an email to Climate Desk that he was "certain that professional climate change deniers will attack the study and the authors, in an effort to discredit this important work," especially given the close ties between the two scientists' research. "It will therefore be looked at as a threat to vested interests who continue to deny that human-changed climate change is a reality."

Marcott admitted he was apprehensive about charging into the fully-mobilized troll army, but said he was grateful scientists like Mann had "gone through hell" before him to build a support network for harassed climate scientists.

"When Michael came along there was a lot more skepticism about global warming, but the public has come a long way," he said. "I'm curious to see how the skeptics are going to take this paper."
