| NASA STUDY REVEALS 2007 RANKS AS SECOND HOTTEST YEAR ON RECORD | G08-036 | 1/16/08 | 10:19 | An analysis of 2007 global temperature data undertaken by scientists at Goddard Institute of Space Studies reveals that 2007 ties with 1998 as the second hottest year on record. 2007 and 1998 are trailed closely by a few years that are minutely cooler, by only 0.01 or 0.02¡ C. 2005 is the warmest year on record, and the eight warmest years in the GISS record have all occurred since 1998. NASA scientists predict that a record global temperature exceeding that of 2005 can be expected within the next two to three years.

| ITEM (1): Short Film on Taking Earth's Temperature - The Earth is a complex system with a unique climate. Many scientists are concerned that Earth's climate is changing at an unprecedented rate. Each January, scientists at NASA Goddard Institute for Space Studies analyze and release annual global temperature data. In their analysis, 2005 ranks as the hottest year on record, and 2007 ties with 1998 as the second hottest year. How do scientists study how warm the planet is, and how do they determine what factors affect its climate? This short film explores the tools NASA scientists use to take Earth's temperature.

| ITEM (2): Visualization of Global Temperature Anomalies from 1977-2007 - Because of a rapid warming trend over the past 30 years, Earth is now experiencing the warmest level of the current interglacial period, or interval between ice ages, which has lasted nearly 12,000 years. This color-coded map displays a progression of changing global surface temperatures from 1977 to 2007. Dark red indicates the greatest warming and dark blue indicates the greatest cooling.

| ITEM (3): Visualization of Global Temperature Anomalies from 1880-2007 - This color-coded map provides a long-term progression of changing global surface temperatures, displaying global temperature anomalies from 1880 to 2007. Dark red indicates the greatest warming and dark blue indicates the greatest cooling.

| ITEM (4): Animations of Ice Albedo - The NASA 2007 temperature data reveals that the greatest warming has occurred in the Arctic. The large Arctic warm anomaly of 2007 is consistent with observations of record low sea ice cover in September 2007. These conceptual animations show how polar ice reflects light from the sun. As this ice begins to melt, less sunlight is reflected back into space. Sunlight is instead absorbed into the oceans and land, raising the overall temperature, and fueling further melting.
