On February 1, 2007, the night before publication of IPCCs report on climate, a study was published saying that temperatures and sea levels have been rising at or above the speed the IPCC reported in 2001. The study compared IPCC 2001 predictions of temperature and sea level change with what actually happened. Over the six years, the actual temperature rise was near the top end of the range given by IPCC's 2001 prediction and the actual rise was more than the top of the range the IPCC predicted.
