1998 was the hottest year on record
| The year 1998 had the highest average global temperature ever recorded, as calculated by scientists at the National Aeronautics and Space Administration (NASA) and the National Oceanographic and Atmospheric Administration (NOAA). The average temperature for 1999 and 2000 is similar to, but only slightly lower than, the record year of 1998. The temperature is determined by averaging thousands of readings from land and ocean weather stations all over the world. |
