Another Global Warming Claim Fails: Yes, The Medieval Warm Period Existed, and Was Worldwide

We know for a fact the Medieval Warm Period was warm. We know this because people wrote down in journals, "Gee, it's really warm."

We also know from things like agricultural records it was warm. England supported a wine industry for the first time in its history, and Greenland actually produced crops. And there were bountiful crops for several hundred years, which we know because people wrote things like, "Gee, we have such bountiful crops that the prices have fallen through the floor. And boy is it ever so warm."

Based on that stuff, we know the Medieval Warm Period was warmer than it is today, and without heavy industry or cars, or petroleum burning, or even much of a world population, so that means it was a natural variation.

This presented a problem for the Global Warming Cultists, who wished to say that the earth had never (or at least through recent human history) ever ever been warmer than it is today.

And yet it was firmly established by historical records that it was quite warm.

This didn't bother the Global Warming Cultists much, though. Determined to make the current age the warmest ever, they simply asserted, without any evidence, that while Europe was indeed warm, the rest of the world was not, and in fact was off-settingly cooler, and thus, on average, the worldwide average temperature during this period was lower than it is today.

Thus, with an asterisk and a footnote reading Because we said so, the Medieval Warm Period was written out of the records. Not until the late 80s-90s had it ever been suggested that the Medieval Warm Period was anything less than positively balmy, much warmer than today, but suddenly with no evidence, upon the mere assertion of the Global Warming Cultists, it was asserted it had never happened. Not really. Not the world over, at least.

Via Poor Richard's News, a new study asserts "No, it was warmer then, and the world over besides, just like we had always thought before the hockey stick graph."

A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that contrary to the ‘consensus’, the ‘Medieval Warm Period’ approximately 500 to 1,000 years ago wasn’t just confined to Europe.

In fact, it extended all the way down to Antarctica – which means that the Earth has already experience global warming without the aid of human CO2 emissions.

An icy limestone crystal called "ikalite" traps evidence of past temperatures by freezing in forms of oxygen which vary with temperature.

The scientists studied ikaite crystals from sediment cores drilled off the coast of Antarctica. The sediment layers were deposited over 2,000 years.

Did the crystals signal a warm period in Antarctica during the Medieval Warm Period? They did.

They were able to deduce this by studying the amount of heavy oxygen isotopes found in the crystals.

During cool periods there are lots, during warm periods there aren’t.

The Global Warming Cultists reacted as scientists are supposed to react to exciting new scientific evidence.
