"WASHINGTON -- There is sufficient evidence from tree rings,
boreholes, retreating glaciers, and other "proxies" of past surface
temperatures to say with a high level of confidence that the last
few decades of the 20th century were warmer than any comparable
period in the last 400 years, according to a new report from the
National Research Council."

So the earth was warmer over 400 years ago. Fascinating.
^^^^^^

errmm ... I think you meant to say: "cooler".

No. If the earth is warmer today than at any time in the last 400 years,
that certainly /implies/ that some time before that the earth was warmer
than today. (Otherwise, why didn't they say 600 years? Or a thousand
years?)

Anyways, AIUI there is quite comprehensive expert concensus that
global warming is indeed currently taking place. The dispute is
over the cause -- human or natural.

Indeed. And also whether unprecedented (many "real" scientists say not).
