An El Niņo weather phenomenon combined with high levels of greenhouse gases are likely to make 2007 the warmest year ever recorded, British climate scientists said today.
U.S. government scientists agree with the assessment.
According to the British forecasters, 2007 will probably be 0.97 degree Fahrenheit (0.54 degree Celsius) above the long-term average of 57 degrees Fahrenheit (14 degrees Celsius).
The current record holder, 1998, was 0.94 degree Fahrenheit (0.52 degree Celsius) above the long-term average. (The average is calculated from the years 1961 to 1990.)
