A press release by the University of East Anglia said that the " trick " was using instrumental data to meet a requirement of showing temperatures more recent than those covered by the proxy based temperature reconstructions, and that the use of the word " trick " was not intended to imply any deception.

Surface temperature data for Earth as a whole, including readings over both land and ocean, show an increase of about 0.8�C ( 1.4�F ) over the period 1901 % 2010 and about 0.5�C ( 0.9�F ) over the period 1979 2010 ( the era for which satellite-based temperature data are routinely available ).

They are both pumped 3 He cryostats, the TL capable of magnetic fields of up to 14 T, and the VL capable of achieving magnetic fields of up to 2 T . The base temperature for both systems is ~ 250 mK . Whilst the basis of operation of system is pumping of liquid Helium 3 below 2.2 K, this low temperature is achieved by first cooling the system to 2.2 K by pumping of Helium 4.
