claim: Mike's Nature trick has nothing to do with hide the decline, instead refering to a technique by Michael Mann to plot instrumental temperature along with past reconstructions.
evidence: In it, Spatially resolved global reconstructions of annual surface temperature patterns were related to changes in greenhouse-gas concentrations, solar irradiance, and volcanic aerosols leading to the conclusion that each of these factors has contributed to the climate variability of the past 400 years, with greenhouse gases emerging as the dominant forcing during the twentieth century.
