In April 2012, the average temperature of Earth's Northern Hemisphere was the warmest of any April in the past 133 years.
Globally, April 2012 marks the fifth warmest April since temperature records began in 1880. It was the 326th straight month with a global temperature above the average for the 20th century.

Data and information was first posted May 15, 2012 by National Oceanic and Atmospheric Administration (NOAA) and its National Climate Data Center (NCDC) in the USA.
Annually, 2011 is the 11th warmest year on record. The year 2010 tied with 2005 as the warmest year.
More details about global temperature are available in the State of the Climate reports (Global Analysis) at the NOAA-NCDC website. These reports present preliminary, global data that has been gathered from monitoring stations and leading institutions around the world. The reports include a Global Hazardssection that gives a global update on drought & wildfires, flooding, storms, severe winter weather, and ecosystems impacts. A Snow and Ice section reports on snow cover in the Northern Hemisphere and sea ice extent in the Northern and Southern Hemispheres.
NOTE: Global temperatures set out in the CO2Now graphic (above) are computed from preliminary NOAA estimates of global average temperature for the 20th century and adding the current 20th-century anomaly.

2000 - 2009 | The warmest decade
Geneva, 8 December 2009 (WMO) The year 2009 is likely to rank in the top 10 warmest on record since the beginning of instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO).

If It’s That Warm, How Come It’s So Damned Cold?
James Hansen, Reto Ruedy, Makiko Sato, Ken Lo
The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world.

Geneva, 16 December 2008 (WMO) The year 2008 is likely to rank as the 10th warmest year on record since the beginning of the instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea-surface and land-surface air temperature for 2008 is currently estimated at 0.31°C/0.56°F above the 1961-1990 annual average of 14.00°C/57.2°F. The global average temperature in 2008 was slightly lower than that for the previous years of the 21st century due in particular, to the moderate to strong La Niña that developed in the latter half of 2007.
The Arctic Sea ice extent dropped to its second-lowest level during the melt season since satellite measurements began in 1979. Climate extremes, including devastating floods, severe and persistent droughts, snow storms, heatwaves and cold waves, were recorded in many parts of the world.
