Thus their endless "correcting" of measurements, faking of curves and suppressing of embarrassments; thus my becoming a Global Warming Cynic.</p> I begin to suspect that the problem is that Global Warm-mongers KNOW that we’ve been in a mild spell (very possibly correctly) and have been frustrated at how hard it is to prove conclusively.

I took cores from some living trees (just second-growth Michigan hardwoods and softwoods generally under 100 years old) and tried to correlate the variations in ring thickness with weather records. IIRC, rainfall had as much influence as temperature - even in Michigan where it never gets really dry - and there were also considerable variations unrelated to anything in the weather records. Diseases, insect infestation, and competition from the other plants for sunlight or root nutrients all play their part, too. </p> Forty-some years ago, I did a school science project on tree-ring samples, with help from my dad, who has a masters in Biology.
