Rising Temperature

temperature projectionsGlobal annual-mean surface temperature has shown a rapid and widespread increase of 1.4º F (0.7ºC) since the early 20th century, with about 0.9º F of that increase occurring since 1978.

The illustration on the left shows different models used by scientists which provide different future climate scenarios. All of them estimate that the global surface temperature will continue to increase over the next one hundred years.

 

Increasing Sea Level

Latest findings by the U.S. National Aeronautics and Space Administration (NASA) and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) show that sea level has increased annually by 0.13 inches or 3.26 mm since 1993.
