“According to co-author Jennifer Mahorasy – who was behind the recent exposure of the scandal in which Australia’s Bureau of Meteorology was found to be erasing record-breaking low temperatures from its records – global temperature has moved up and down quite naturally for the last 2000 years.
We began by deconstructing the six-proxy series from different geographic regions – series already published in the mainstream climate science literature. One of these, the Northern Hemisphere composite series begins in 50 AD, ends in the year 2000, and is derived from studies of pollen, lake sediments, stalagmites and boreholes.
Typical of most such temperature series, it zigzags up and down while showing two rising trends: the first peaks about 1200 AD and corresponds with a period known as the Medieval Warm Period (MWP), while the second peaks in 1980 and then shows decline. In between, is the Little Ice Age (LIA), which according to the Northern Hemisphere composite bottomed-out in 1650 AD. (Of course, the MWP corresponded with a period of generally good harvests in England – when men dressed in tunics and built grand cathedrals with tall spires. It preceded the LIA when there was famine and the Great Plague of London.)
Up until the 1990s, this was widely accepted by the climate science community. But then came a concerted effort led by alarmists including Michael “Hockey Stick” Mann to erase the Medieval Warming Period from the records. Scientists who argued otherwise – among them Willie Soon and Sallie Balliunas – were harassed for their “incorrect” thinking.
However, the new study would appear to confirm that the skeptics were right all along – and that it’s the alarmists who have some apologizing to do.”
I’ve never bought the Global Warming shtick. When everyone is jumping on a bandwagon, it’s usually going in the wrong direction. The hysteria over climate change has been ridiculous.
Nature has cycles. Heck, there once were palm trees at the south pole.
I’m not worried.
