The scientist behind the so-called "climate-gate" e-mail scandal now admits there has been no statistically significant global warming since 1995.
Professor Phil Jones also notes that scientists are unsure whether the Medieval Warm Period was actually warmer than current temperatures.
Some skeptics say that is the first time a senior scientist working with the U.N. report on climate change has admitted the possibility that the time between 800 and 1300 A.D. could have actually been warmer than present temperatures. That would be a blow to global warming believers.
Jones also admitted some of his weather data was not organized well enough and that contributed to his refusal to share raw data with critics. But Jones maintains he's just a scientist doing a job: "I have no agenda."
