Dear Mr. Pearce
Yesterday, whilst waiting for my wife to join me in Marks and Spencer, I chanced to glance at the latest edition of New Scientist, in which your contribution appears [Tree rings suggest Roman world was warmer than thought]. I confess that, both for reasons of time and from a sense of disenchantment anyway with the populist rag, I did little more than skim read. However, I think that enough was gleaned legitimately to allow for comment.
The thrust of your piece was that the handle of the hockey stick was, in fact, correct. Somebody's recent study of tree rings had indicated that, whilst they might or might not be wider or narrower, much could be deduced from their density. From this it had been concluded that the past two thousand years had seen a warm temperature continuum of remarkable consistency up to about the middle of the 19th century, say. This, in turn, explained why our forebears had been able to cultivate vines as far North as York. Thence, the conclusion seemed to be drawn that Mann had been right all along in claiming a perilous temperature increase from roughly the advent of the Industrial Revolution, the blade.
Of course, MacIntyre's undermining of Mann's little frolic was not so much upon scientific grounds although, God knows, there was much science to it, as upon his blithe disregard for statistical rigour. You make no mention of this. Why, pray? Neither do you make any mention of Briffa's equally egregious pseudo-science directed at sustaining the original Mann fiction. You also overlook circumstances that are richly supported by multi-stranded evidence. Examples? Well, how about the fact that:

Climate: While CBS touts a "groundbreaking" government report linking extreme weather and climate change, German researchers find 2,000 years of cooling and warmer temps in medieval times and the Roman era.
This summer's heat wave has given the global warmongers new hope in conning the hot and the restless into believing the whole thing is due to that SUV parked in your driveway and that coal-fired plant down the street.
Not so fast, say German researchers who documented a two millennia cooling trend. Both the Roman legions and Crusaders marched in warmer climes.
On Wednesday's CBS This Morning, CBS News correspondent Wyatt Andrews breathlessly intoned that a recent study from the National Oceanic and Atmospheric Administration (NOAA) had established "the first-ever statistical connection between extreme weather and man-made climate change" and that the study "found that man-made heat made the Texas drought roughly 20 times more likely."

Tree ring study gives first accurate climate reading back to 138BC
World has been slowly cooling for 2,000 years
World was warmer in Roman and Medieval times than it is now
Study of semi-fossilised trees in Finland
Rings in fossilised pine trees have proven that the world was much warmer than previously thought - and the earth has been slowly COOLING for 2,000 years.
Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun.
The finding may force scientists to rethink current theories of the impact of global warming.

The reconstruction provides a high-resolution representation of temperature patterns in the Roman and Medieval warm periods, but also shows the cold phases that occurred during the Migration Period and the later Little Ice
This is what global cooling really looks like – new tree ring study shows 2000 years of cooling – previous studies underestimated temperatures of Roman and Medieval Warm Periods
