Medieval

New Study Adds To Glacial Ice Confusion

In a new report in Science, scientists present results matching neither the hypothesis of inter-hemispheric synchrony during the mid to late Holocene nor rhythmic asynchrony, downplaying the importance of global driving mechanisms. It seems that several glacier advances occurred in New Zealand during classic northern warm periods. Understanding the relationship between climate changes in the northern and southern hemispheres during the Holocene, along with their causes, remains a major problem of climate science.

Climate Change Spin Doctors

Increased scrutiny of climate catastrophists' claims is leading to panic among the promoters of global warming hype. Rather than attempting to counter mounting evidence that global warming—at least as defined by the IPCC and its supporters—is not a valid scientific theory, a number of leading catastrophists have issued a public call to climate scientists. Their plea? Further dumbing down climate science by using a simplified “common climate language” to “advance the public's decision-making capacity.”

Medieval Warm Period Rediscovered

A recent article in the journal Science has provided a new, detailed climate record for the Medieval Climate Anomaly (MCA), also know as the Medieval Warm Period. It was the most recent pre-industrial warm period, noted in Europe and elsewhere around the globe. The researchers present a 947-year-long multi-decadal North Atlantic Oscillation (NAO) reconstruction and find a persistent positive NAO during the MCA. The interesting thing is that the MCA had basically been removed from the climate record by Michael Mann's infamous “hockey stick” history graph that was adopted by the IPCC a decade ago.

New Year's Climate Cornucopia

Here are some interesting climate related tidbits from the science news feeds; food for thought in the new year. First, researchers at the University of Oregon have discovered evidence linking the disappearance of North American megafauna, the Clovis people and the onset of the Younger Dryas period to a comet impact. For years scientists have blamed the disappearance of the American Mammoth, Mastodon, saber toothed cats and other large land animals on human predation or climate change.
