Interesting research - Deceptive and biased reporting
"Unfortunately if you believe that isolated events prove theories, you would pretty much have to accept that global warming has stopped: ten to fifteen years of flat temperatures, or even a few very cold winters - both of which have just happened - are a lot more significant than one storm (and they atill aren't significant enough to mean anything much in a climate context)."
This kind of bias has no place in a publication that purports to provide any level objectivity or useful science reporting. Most of the media has pointed out that there has been an increase in severity of weather events lately and has asked anyone they can get on, from scientists to insurance eggheads, whether it is related to Global Warming; most have said "we don't know for sure".
In this case, the fluke that it was exceptionally warm for one year 15 years ago is used to distort the fact that that global temperatures are rising on a consistent basis. If you look at the past 10 years, 20 years or 50 years, temperatures are rising; it is only when you use 15 years that you get a flat "trend".
As others have pointed out, this research posits that man made climate change is real, but that there may be offsetting factors that mean it could be keeping us from going into an ice age. That is a big supposition, and based on reading of the geological record that can also be interpreted in very different ways.
If we are driving up temperatures so fast that we cause major sea rise and weather disruptions over the next 50 years, it really won't matter if the natural trend would have been going the other direction (over a period of hundreds of years); the economic and human welfare disruptions will be massive.
