We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low. Such findings are also significant with regard to climate policy, as they will influence the way today's climate changes are seen in context of historical warm periods.

When the exact same data set can be used to justify today's claims of global warming as was used just thirty years ago to support claims of global cooling, the science is truly in question.

There is no consensus, except among dedicated feeders at the public trough, and their only consensus is that there is a PROBLEM that requires lots of MONEY to SOLVE.

I swear to Christ, I expect next year we'll be hearing that the climate isn't changing ENOUGH.
