Lord Deben just asked me on Twitter why he should trust me and not official versions of "the science". I gave him a raft of reasons, but then came across this posting on Unthreaded from Brent Hargreaves:
GISS record of temperature at Teigarhorn, Iceland:
Feb 1901: 0.0C - reported Nov 2011
Feb 1901: -0.9C - reported Mar 2012
Feb 1901: -1.2C - reported Aug 2013
Brent has a full post about what he has found here, but for me his findings seem like a pretty good reason to distrust the official tale.
