Heh - the latest Global Warming cry unravels

From the Vancouver Observer:

We just experienced 4,000 years of global warming in two decades
A new study published in the journal Science shows how freakishly extreme global warming has become in the last few decades.

The scientists from Oregon State University and Harvard University used dozens of sources of ice cores and sediment cores from around the world to reconstruct the Earth�s temperature record for the last 1,100 decades. This detailed record stretches back much farther than previous studies.

Global temperatures rose slowly for thousands of years after the end of the last ice age. Temperatures peaked around 5,000 BC, at a level close to where we are today. Then temperatures declined slowly for thousands of more years.

Now, suddenly, the global temperature has started rocketing upwards. Far more troubling than the actual temperature is the fact that the changes are accelerating dramatically.

The century from 1860 to 1960 saw rapid warming. The next two decades more than doubled that warming. And then the next two decades � 1980 to 2000 � went ballistic, piling on thousands of years of warming.

The paper: "A Reconstruction of Regional and Global Temperature for the Past 11,300 Years" authored by Shaun A. Marcott et. al. was completely debunked -- by their own published data -- in the first two weeks after publication. From John Kehr writing at Watts Up With That:

Where�s the hockey stick? The �Marcott 9′ show no warming past 1950
While it took me a while to get the time together to write an article about the Marcott paper, that does not mean I have not been looking at it and discussing it from nearly the day it was released. There has been volumes of discussion within The Right Climate Stuff group that I have been involved with. The ones that lean towards CO2 as something to be concerned about were initially rather excited about this paper, but that has taken a course correction as it has become clear how poor the science is in the Marcott paper.

What follows is a detailed smack-down of the shoddy science used in the Science paper. I can now consider Science to be a Political journal and no longer a Scientific one. It is a shame that publications like the Vancouver Observer fail to check their facts especially when the data is out there ready for them to look at. But it sounded right -- it fit our agenda and we wanted to believe. The author maintains this website: Visual Carbon -- no bias there. Children...
