Approximately 1,000 weather reporting stations all over the world have been monitoring local temperatures for decades. Temperature data have been compiled and analyzed by NASA scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.
Nine of the 10 warmest years on record have occurred since the year 2000. The tenth? From the 20th Century, that was 1998. Temperature rise is not completely steady and consistent from one year to the next. That is due to factors such as volcanic eruptions and other natural causes; however, trends are the important thing.
We can see from the short video below the flip that Earth continues to experience warmer temperatures than several decades ago. The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline. Weather experts warn that a consistent global average change of even a half-degree Fahrenheit can have catastrophic effects on global weather patterns. Anyone recall April and May 2011?
