Global warming: Earth heated up in medieval times without human CO2 emissions | Mail Online

The ice, I mean the plot, thickens

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.

Your going to burn in hell along with Zunli for stating anything against the proven man made global warming fact.

Nah. I doubt it. I just like detailed conversations. And there have been an increasing number of non-tinfoil hat articles and journals about a swing, perhaps, to more reasonable discussion of gw as opposed to he chicken little sky is falling mantra that has been the only socially acceptable position since the inconvenient truth-capade.

So in Science, we call this New Evidence and it shifts mindsets about what we know.

But how can you know something then have new evidence shift your mindset? You either KNOW it or you dont.

Im simply saying we can guess and have educated guesses but we dont "know" shit about this just yet.

I am semi-comfortable with a term known as Ambiguity. I can see how someone of your history would have a problem with this.

Come on Al, I expect better.

First, don't take your science from the Sun. Here's the original paper.

Kennedy H., Kennedy D. P., Papadimitriou S., Lu Z., Rickaby R. E. M., Lennie A. R., Tang C. C., The effect of dissolved phosphorus and magnesium on the temperature of synthesis of ikaite (CaCO3·6H2O) and the implications for glendonite formation. (Under review, Geochim. Cosmochim. Acta)

They studied a form of limestone that melts at a relatively low temperature, and verified that the medieval warm period was not just a European phenomena. He makes no statements about how this affects the hypothesis of man-made global warming, because his paper doesn't refute or support it.

Equally important - this isn't evidence against man-made global warming. The fact that there have been warm and cool periods does nothing to weaken the arguments for man-made global warming, it's very well known that there are warm and cool periods on Earth as well as other planets.

Here's another article on the same subject by the same guy. I'm not sure which of these two this article is based off of.

Lu, Z., Rickaby, R.E.M., Kennedy H., Kennedy, P., Shaw S., Lennie, A., Pancost, R.D., Wellner, J., and Anderson, J.B., An ikaite record of late Holocene climate at the Antarctic Peninsula. (Under review, Earth and Planetary Science Letters)
