Year-to-date Temperature Anomalies

"The first six months of 2012 were the warmest on record for the contiguous United States as a whole, and for many locations across the United States. The following table shows, for about 150 long-term stations, how Jan-Jun 2012 stacks up against normal, and where it ranks among that station's history. The unusualness score is based upon the number of standard deviations difference between the 2012 value and the station's average, based on the station's history..."

NOAA: Year-to-Date Global Temperature Ties for Warmest on Record
"he first nine months of 2010 tied with the same period in 1998 for the warmest combined land and ocean surface temperature on record. The global average land surface temperature for January-September was the second warmest on record, behind 2007. The global ocean surface temperature for January–September was also the second warmest on record, behind 1998.

The monthly analysis from NOAA’s National Climatic Data Center, which is based on records going back to 1880, is part of the suite of climate services NOAA provides government, business and community leaders, so they can make informed decisions.

Global Temperature Highlights
For the year-to-date, the global combined land and ocean surface temperature of 58.67 F (14.75 C) tied with 1998 as the warmest January-September period on record. This value is 1.17 F (0.65 C) above the 20th century average.

The combined global land and ocean average surface temperature for September 2010 tied with 1998 as the eighth warmest on record at 59.9 F (15.5 C), which is 0.90 F (0.50 C) above the 20th century average of 59.0 F (15.0 C)..."

NOAA: Past Decade Warmest on Record According to Scientists in 48 Countries
"The 2009 State of the Climate report released today draws on data for 10 key climate indicators that all point to the same finding: the scientific evidence that our world is warming is unmistakable. More than 300 scientists from 160 research groups in 48 countries contributed to the report, which confirms that the past decade was the warmest on record and that the Earth has been growing warmer over the last 50 years.

Based on comprehensive data from multiple sources, the report defines 10 measurable planet-wide features used to gauge global temperature changes. The relative movement of each of these indicators proves consistent with a warming world. Seven indicators are rising: air temperature over land, sea-surface temperature, air temperature over oceans, sea level, ocean heat, humidity and tropospheric temperature in the “active-weather” layer of the atmosphere closest to the Earth’s surface. Three indicators are declining: Arctic sea ice, glaciers and spring snow cover in the Northern hemisphere..."

Fifth Warmest July on Record for Globe
"The combined average global land and ocean surface temperature for July 2008 tied with 2001 and 2003 as the fifth warmest July since worldwide records began in 1880, according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C.

Also, the seven months from January to July 2008 ranked as the ninth warmest seven-month period for combined average global land and ocean surface temperature."
