The National Oceanic and Atmospheric Administration (NOAA) released their monthly report on global climate. The findings show that July 2010 was the 2nd warmest July on record, second only to July of 1998.Also from the period of January through July had the warmest average ever recorded. NOAA also found that the global sea surface temperatures were the fifth warmest on record for the month of July and for the period of January through July 2010 it was the 2nd warmest period, the warmest was recorded in 1998. July was the 305th consecutive month with a global temperature above the 20th century average.
Couple of interesting facts from the data shows we had a very wet July on a global scale which includes the monsoon season in Pakistan that has caused deadly flooding over a very wide spread region of the Peshawar province. The flooding in Pakistan is the worst since 1929. Also the Arctic ice shelve was 16.9 percent below the average from 1979 to 2000 and was the second lowest on record. The record low for the month of July was in 2007. However we had a reversal of melting ice on the Antarctic ice shelve with a record 4.8 percent growth, which is the largest, recorded for the month of July.
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.
• The combined global land and ocean average surface temperature for July 2010 was the second warmest on record, behind 1998, at 16.5°C (61.6F), which is 0.66°C (1.19°F) above the 20th century average of 15.8°C (60.4°F).
• The July worldwide land surface temperature was 1.03°C (1.85°F) above the 20th century average of 14.3°C (57.8°F)—the warmest July on record.
• The worldwide ocean surface temperature was 0.54°C (0.97°F) above the 20th century average of 16.4°C (61.5°F) and the fifth warmest July on record. The warmth was most pronounced in the Atlantic Ocean.
• La Niña conditions developed during July 2010, as sea surface temperatures (SST) continued to drop across the central and eastern equatorial Pacific Ocean. According to NOAA’s Climate Prediction Center, La Niña is expected to strengthen and last through the Northern Hemisphere winter 2010-2011.
• For the year-to-date, the global combined land and ocean surface temperature of 14.5°C (58.1°F) was the warmest January-July period on record. This value is 0.68°C (1.22°F) above the 20th century average.
