Faster Rate of Global Warming Seen in Temperature Records
February 22 — Researchers at NOAA's National Climate Data Center have found evidence that the rate of global warming is accelerating and that in the past 25 years it achieved the rate of 2degrees Celsius (4 degrees Fahrenheit) per century. The study published in Geophysical Research Letters concludes that there is only a 1-in-20 chance that the string of record high temperatures in 1997-1998 was simply an unusual event, rather than a change point, the start of a new and faster ongoing trend.
