Weather Eye with John Maunder

Global temperatures are compiled for various areas, including global (land-ocean), global (meteorological stations), three latitude bands, and hemispheric, by the Goddard Institute for Space Studies of NASA.

A graph of the global temperatures (for the land/ocean) from 1880 to 2013, show a general warming from 1910 to the early 1940s, a cooling from the early 1940s to the mid-1970s; and a general warming from the mid-1970s to about 1998.

However, since then, global annual temperatures have been relatively steady with no real cooling or warming.

The yearly global temperatures (expressed as differences from the 1951-1980 average), since 1998 are:

1998: +0.58 degrees Celsius

1999: +0.33 degrees Celsius

2000: +0.35 degrees Celsius

2001: +0.48 degrees Celsius

2002: +0.56 degrees Celsius

2003: +0.56 degrees Celsius

2004: +0.49 degrees Celsius

2005: +0.62 degrees Celsius

2006: +0.55 degrees Celsius

2007: +0.58 degrees Celsius

2008: +0.49 degrees Celsius

2009: +0.59 degrees Celsius

2010: +0.66 degrees Celsius

2011: +0.55 degrees Celsius

2012: +0.57 degrees Celsius

2013: +0.60 degrees Celsius
