Toddler, the hockey stick has been confirmed multiple times. Just because you are an ignoramous to lazy to research does not mean the rest of us are.
What evidence is there for the hockey stick?
Hockey stick is broken
"In 2003 Professor McKitrick teamed with a Canadian engineer, Steve McIntyre, in attempting to replicate the hockey stick and debunked it as statistical nonsense. They revealed how the chart was derived from 'collation errors, unjustified truncation or extrapolation of source data, obsolete data, incorrect principal component calculations, geographical mislocations and other serious defects', substantially affecting the temperature index." (John McLaughlin)
What the science says...
Since the hockey stick paper in 1998, there have been a number of proxy studies analysing a variety of different sources including corals, stalagmites, tree rings, boreholes and ice cores. They all confirm the original hockey stick conclusion: the 20th century is the warmest in the last 1000 years and that warming was most dramatic after 1920.
