Synopsis |
| SATELLITES ACT AS THERMOMETERS IN SPACE: SHOW EARTH HAS FEVER | G04-021 | 4/15/04 | 3:02 | Like a thermometer in space, satellites are taking the temperature of the Earth's surface or skin, and confirm that the Earth has had an increasing "fever" for decades, according to scientists. 2003 was a record-breaking year for temperature in Western Europe. Now for the first time, satellites have been used to develop an 18-year record (1981-1998) of global land surface temperatures, providing better proof that Earth's snow-free land surfaces have, on average, warmed during this time period, according to a NASA study using data from the National Oceanic and Atmospheric Administration (NOAA) and NASA satellite assets.

| ITEM (1): Global Temperature Map - Until now, global land surface temperatures Used in climate change studies were derived from a relatively sparse set of ground station readings from around the world. Satellite temperature measurements provide global coverage at much higher resolutions. The following visualization shows global land surface temperatures taken every 32 days from April 2000 through February 2004. These images were derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra and Aqua satellites.

| ITEM (2): Record-Breaking Heat Wave in Europe 2003 - A massive heat wave that scorched Europe in July and August 2003, killed more than 19,000 people, making it one of the deadliest hot-weather disasters in a century. The following visualization provides a close-up view of Europe with an 8-day MODIS land surface temperature composite for the record-breaking final week of July 2003. Courtesy: NASA

| ITEM (3): Red-Hot Europe 2003, Compared to 2001 - In the red-hot months of July and August 2003, France was by far the hardest hit, reporting a staggering heat wave death toll of 14,802 in late September. Central France was nearly 10 degrees C (18 degrees F) warmer in July 2003 than in the same month two years prior. The following visualization shows difference in temperature between the two years with the color red representing a change of up to +10 degrees C and blue representing a change of up to Ð10 degrees C.
