July Ocean Temperature Hits Record High—Again

Last month, Earth’s ocean surfaces tied the previous record for the hottest July during the 130 years the U.S. government has been compiling data.

The National Climatic Data Center of the National Oceanic and Atmospheric Administration (NOAA) reported that the average temperature was 62.56 degrees Fahrenheit, 1.06 degrees above the 20th-century average. The ocean surfaces also reached that temperature in July 2009. It's the third straight month this year that ocean surface temperatures set a record.

The NOAA reported:

Much warmer than average and record warm temperatures were prevalent in every major ocean basin, particularly notable across parts of the Arctic Seas between Greenland and northern Europe, the southern Indian Ocean, and the western equatorial Pacific Ocean. Neither El Niño nor La Niña conditions were present across the central and eastern equatorial Pacific Ocean during July 2014. Temperature departures from average in this region, a major indicator of the conditions, cooled slightly compared with the previous month.

Other July statistics from the NOAA:

The combined average temperature over global land and ocean surfaces for July 2014 was the fourth highest on record for July, at 1.15°F above the 20th-century average of 60.4°F.

The global land surface temperature was 1.33°F above the 20th-century average of 57.8°F, marking the 10th warmest July on record.

The combined global land and ocean average surface temperature for the January–July period (year-to-date) was 1.19°F above the 20th-century average of 56.9°F, tying with 2002 as the third warmest such period on record.

When Europeans first arrived in North America, Atlantic puffins were common on islands in the Gulf of Maine. But hunters killed many of the birds for food or for feathers to adorn ladies' hats. By the 1800s, the population in Maine had plummeted.
