Locally here in NM, what this new release of documents does immediately is give credence to those who say the “global warming” science is far from being settled and should make easier the job of experts testifying in two state regulatory hearings to overturn regulations reducing/capping industrial CO2 emissions. These were rushed to adoption in the waning days of the Richardson administration after the new Republican governor Susana Martinez had been elected. She fired the regulatory board and appointed new members more in line with reality than environmental hand-wringing.
