Breaking the Hockey Stick

The infamous Hockey Stick Graph (above) started the whole cycle of global warming alarm-ism. Many skeptics claimed the graph wrongly used statistical techniques to 'smooth' out the well known Medieval Warm Period. The Intergovernmental Panel on Climate Change (IPCC) and Hockey Stick supporters claimed the Medieval Warm Period was limited to Europe and the Northern Hemisphere. They denied it was really global warming. At the time, the Earth only had a quarter of a billion human inhabitants and man-made CO2 was minimal. Well, a new proxy proves they are wrong. Antarctica warmed too during the Medieval Warm Period.

(Daily Mail) — Current theories of the causes and impact of global warming have been thrown into question by a new study which shows that during medieval times the whole of the planet heated up.

It then cooled down naturally and there was even a ‘mini ice age’.

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.

At present the Intergovernmental Panel on Climate Change (IPCC) argues that the Medieval Warm Period was confined to Europe — therefore that the warming we’re experiencing now is a man-made phenomenon.

However, Professor Lu has shown that this isn’t true — and the evidence lies with a rare mineral called ikaite, which forms in cold waters.

‘Ikaite is an icy version of limestone,’ said Lu. ‘The crystals are only stable under cold conditions and actually melt at room temperature.’

It turns out the water that holds the crystal structure together — called the hydration water — traps information about temperatures present when the crystals formed.

This finding by Lu’s research team establishes, for the first time, ikaite as a reliable way to study past climate conditions.

Here is what the Hockey Stick graph should really look like when the Medieval Warm Period is included..
