I was going to write my own response to the Yamal Implosion and the work that Steve McIntyre has done to expose what appears to be deliberate and wilful fraud in the science behind the infamous "hockey stick" and to write what that means.
However, a commenter on the excellent wattsupwiththat blog (science blog of the year) has already written this in far better terms than I could. So with full attribution to wattsupwithtthat.com and to the poster of the comment, I paste his comment here:

Richard (02:41:50) :
This is what I gather is the larger implication of the Yamal hockey stick saga:
Ross McKitrick: “Here’s a re-cap of this saga that should make clear the stunning importance of what Steve has found… the Schweingruber data completely contradicts the CRU series… Combining the CRU and Schweingruber data yields .. a medieval era warmer than the present…”
All the spaghetti graphs of the temperature in the IPCC report breakdown.
The IPCC says, based on these spaghetti graphs utilising Briffa’s cherry picked Yamal data, – “Palaeoclimatic information supports the interpretation that the warmth of the last half century is unusual in at least the previous 1,300 years.”
Now suddenly this is not so. The medieval warm period, when all the Yamal data is used, without cherry picking, shows up clearly as warmer than the present. There is nothing unusual in the warmth of the last half century.
The IPCC also says that “Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG concentrations.” Why?
Because “Observed patterns of warming and their changes [in the last 50 years] are simulated only by models that include anthropogenic forcings.”
If the models couldn’t simulate the changes of the last 50 years without including “anthropogenic forcings”, which are due to “the observed increase in anthropogenic GHG concentrations”, they could not possibly simulate the warmer medieval era either, without these “anthropogenic forcings”.
This is enigmatic. There were no “anthropogenic forcings” in the medieval era.
Could it then possibly be there is something commonly wrong in all these climate models?
Also if there is nothing unusual in the warmth of the last half century, then where is the cause for alarm? Why are we spending billions of dollars trying to alleviate or avoid a problem that doesnt exist? Why must we shut down our power plants, curtail our manufacturing and production, reduce our gross national products and legislate global poverty as a solution to a threat that doesnt exist?
We are spending billions of dollars frantically trying to button up the Emperors new coat only to discover he has no clothes.

Couldn't have put it better myself, which is why I nicked it!
