Except actual temperature measurements over the past two decades confirm the original trend that was predicted.
An independent assessment of Mann's hockey stick was conducted by the National Center for Atmospheric Research (Wahl 2007). They reconstructed temperatures employing a variety of statistical techniques (with and without principal components analysis). Their results found slightly different temperatures in the early 15th Century. However, they confirmed the principal results of the original hockey stick - that the warming trend and temperatures over the last few decades are unprecedented over at least the last 600 years.
You left out the money factor. Scientists have been paid to come up with certain conclusions. Look at early research into smoking. Those scientists were paid to come to the conclusion that smoking was not harmful. The original research into artificial sweeteners was flawed, but backed up by other scientists. The first research on saccharine said that it caused cancer. Turned out that rats were being fed the equivalent of a human drinking gallons of straight saccharine daily. When they got normal amounts, there was no cancer increase. Several climate scientists have said that they were offered money(grants) to back man-made global warming. Drugs are turned out every year that are dangerous because company-owned scientists are paid to fake or ignore results.
You can go back a few hundred years, the churches pressured scientists to agree with their beliefs.
Here is my original post with a few examples of scientists lying. Guess you can't comprehend.
A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.
The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.
According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.
TEPlimey, you post proves my point. Scientists lie.
