2005 Was Warmest Year on Record - NASA
WASHINGTON - Last year was the warmest recorded on Earth's surface, and it was unusually hot in the Arctic, US space agency NASA said on Tuesday.
All five of the hottest years since modern record-keeping began in the 1890s occurred within the last decade, according to analysis by NASA's Goddard Institute for Space Studies.
In descending order, the years with the highest global average annual temperatures were 2005, 1998, 2002, 2003 and 2004, NASA said in a statement.
A consistent pattern of a hotter climate for earth's biosphere, will bring vast changes for humanity.
