A bit quick out of the starting gate, there.
I've only had time to plow through a small part of the total paper, and I would submit that there are some perspectives being left out. For example, the temperature from ice core data has fluctuated rapidly between +2 and -2 degrees C for the past 10,000 years, after spiking up from -8 degrees 20,000 years ago. The graph from the current study is almost lost in the noise when taken across a larger time span.
However, it's premature and almost certainly incorrect to label all the wide range of data in this study crap.
I suspect most of the crap will be found in what the largely ignorant media says about it.
