According to scientists at the National Oceanographic and Atmospheric Administration, 2010 ranks in a statistical tie with 2005 as the warmest year on record for the globe.
Along with its report on the subject, NOAA lists many worldwide weather events that may or may not be connected to that record temperature's effect on climate change though the record is almost certainly a result of global warming. Every year since the mid-'70s has ranked above the 20th century average temperature, and all of the Top 10 warmest years on record, since 1888, have been measured since 1998.
Global warming is fueled by greenhouse gas pollution, primarily from burning fossil fuels like coal and oil. The Daily Green publishes daily going green tips to help you lighten your footprint.
Weather is weather and climate is climate; there have always been extreme weather events. These events, while they can't be said to be caused by global warming, are consistent with the climate change researchers say we should expect in a warmer world.
So what climate changes were brewing in the record-hot year that was?
