Now, as has been widely reported, scientists at NOAA have examined the historical data and have determined the so-called hiatus never occurred.Their paper, appearing in the journal Science, states "There is no discernible ... decrease in the rate of warming between the second half of the 20th century and the first 15 years of the 21st century."
The problem has been biases in the data.You don't just collect data from some instrument and run with it. You have to calibrate an instrument to determine exactly what it is measuring. Then the data must be examined to ensure the instrument continues to work the same over time. Additionally, you have to take into account where you have data and where you don't. In the case of climate science, you want to take into account the fact we have lots of data from the land surfaces, but not the oceans. These are just a few of the issues with data. The NOAA scientists have discovered when you take all of this into account the 'hiatus' disappears. Surface warming has continued at the rate of about two-tenths of a degree Fahrenheit per decade (about .1 degree C per decade) since the 1950s. Take a look:
So, how does this qualify as validating the results? Very simple. It will take real scientists months to years to examine this paper and attempt to duplicate the results. All of these former scientists rushed out and criticized the results after a mere week. But, there is no possible way for them to have determined if the results are valid or not. The only explanation for their rushed criticisms is that the denier lobby is concerned with this paper. And, if they are concerned, that indicates the results are very persuasive.This is a true indicator the results are valid.
You have to wonder, why are the deniers in such a rush to try and discredit the paper? Probably because they know it proves their denier claims are not valid. So, they have no choice but to rush to the attack, even though it is not possible for them to have examined the results.
