Synopsis |
| 1998 GLOBAL TEMPERATURE SMASHES RECORD | G98-063 | 12/17/1998 | 00:49:00 | In 1998, global surface temperatures set a new record, report researchers at NASA's Goddard Institute for Space Studies (GISS). For the first time, scientists released data visualizations showing global temperature anomalies since 1950. |
TAPE CONTENTS: |
| ITEM (1): GLOBAL TEMPERATURE ANOMALIES SINCE 1950 - Global surface temperatures in 1998 set a new record for the period of instrumental measurements, report researchers at the NASA Goddard Institute for Space Studies who analyze data collected from several thousand meteorological stations around the world. This visualization shows surface temperature anomalies from 1950 through November, 1998. The 1998 warmth was associated partly with a strong El Nino that warmed the air over the eastern tropical Pacific Ocean in the first half of the year and in turn affected weather around the world. Red and yellow colors indicate warmer than normal conditions and blue colors indicates cooler than normal conditions

ITEM (2): U.S. TEMPERATURE ANOMALIES SINCE 1950 - The largest temperature anomalies in 1998 were in North America in a pattern that commonly occurs in El Nino years. This visualization shows surface temperature anomalies from 1950 through November, 1998. Scientists use data from rural stations to correct for urban influences on reported temperatures. Red and yellow colors indicate warmer than normal conditions and blue indicates cooler than normal conditions.
