Summer of 2013 the 8th warmest on record


A tale of two summers …

Warm West, cool East

By Summit Voice

FRISCO — Despite the near absence of record heat across the contiguous 48 states, the summer of 2013 (June-August) ranked as the eighth-warmest on record, with an average temperature of 72.6 degrees, about 1.2 degrees warmer than the 20th century norm.

The data tallied by the National Climatic Data Center suggests an era of new normals, with temperatures running well above historic averages even in non-El Niño years. Taken separately, August 2013 was the 28th-warmest on record with an average temperature of 73..1 degrees, 1 degree above the 20th century average. Read the full report here.

The Alaska statewide average summer temperature was 2.7 degrees above the 1971-2000 average and ranked as the second warmest summer in the 96-year period of record for the state. The warmest June-August occurred in 2004 when the statewide temperature was 4.1 degrees above average. Continue reading

FRISCO — With an average temperature that was .9 degrees below the 20th century average, the contiguous 48 U.S. states recorded the coldest March readings since 2002, when the monthly average was a whopping 2.2 degrees below average.

The monthly readings mark a huge contrast from one year ago, when the U.S. recorded its warmest-ever March, according to the National Climatic Data Center, which released the monthly State of the Climate report today (April 15). Continue reading

January brings record warmth to southern hemisphere

Global land and sea surface temps tied with 1995 as ninth-warmest


January 2013 marks the 335th month with global temps above average.

By Summit Voice

FRISCO — Southern hemisphere land areas reported their warmest January readings on record, including Australia, where January 2013 was the hottest month ever recorded, according to NOAA climate scientists, who released the global state of the climate report this week. A slide show from the presentation is online here.

The Southern Hemisphere was record warm over land for the second month in a row. Record high monthly temperatures were observed over northeastern Brazil, much of southern Africa, and northern and central Australia. No land areas in the Southern Hemisphere were cooler than average.

While some northern hemisphere land areas reported below-average temperatures for the month, global land and sea surface temperature averaged out to tie with 1995 as the ninth-warmest on record, at .97 degrees above the 20th century average of 53.6 degrees. Even with cooler than average readings in some parts of the northern hemisphere, the average temperature was still 1.48 degrees above average, the 21st-warmest January on record.

Climate: September 2012 ties 2005 as warmest ever


2012 likely to be warmest La Niña year on record

By Summit Voice

FRISCO — You know something is up when the incessant shrieks from global warming deniers get louder than ever. Last week’s refrain was, “global warming ended 16 years ago,” based on  incomplete and cherry picked data from the UK.

Instead, the official numbers just released by the National Climatic Data Center show that Sept. 2012 tied 2005 for the warmest global September on record since 2005, despite the fact that the U.S. (only a small percentage of the globe) didn’t come close to setting a record average high temperature.

SUMMIT COUNTY — Very warm land-surface temperatures around the world helped propel April 2012 into the top five warmest Aprils on record for the planet, marking the largest departure from 20th century averages since Nov. 2010, at the beginning of a two-year La Niña episode.

The combined global average land and sea surface temperature for the month was 57.87 degrees, more than one degree above the long-term norm, according the National Climatic Data Center monthly summary. It was the 36th April in a row with above-average readings. The last time April temps were below average was in 1976.

Despite the remnant effects of a fading La Niña, the global average sea surface temperature was .68 degrees above the 20th century average, the 11-warmest on record. Continue reading

Climate: March 2012 the 16th-warmest on record

North America and northwestern Europe locations set high temperature records, with colder-than-average readings in Australia and much of Russia

SUMMIT COUNTY —A record heat wave in the eastern and central U.S. helped push March 2012 into the top 20 hottest years on record for planet Earth, with an average global temperature that was .83 degrees above the 20th century average. The last time global March temperatures were below average was in 1976; the last month on record with below average temps was February 1985, according to the monthly update from the National Climatic Data Center.

Overall, March 2012 was the 16th-warmest March on record, but the coolest since 1999. Global temperatures were marked by extreme warmth and cold across most land masses, especially in the northern hemisphere’s mid- and high latitudes, with warmer-than-average readings across most of Canada, the contiguous United States, Mexico, Argentina, Europe, and parts of northern and central Russia.

Climate: January sizzles; U.S. temps 4th-warmest ever

U.S. Snow-cover extent the third-lowest on record

Every state but Washington reported above- to well-above average temps during January 2012.

By Summit Voice

SUMMIT COUNTY — Despite a moderate La Niña in the Pacific, January temperatures across the U.S. climbed to near-record levels for the month, according to the National Climatic Data Center monthly stats released today.

The average temperature, compiled from hundreds of weather stations across the country, was 5.5 degrees above the 1901-2000 average, making it the fourth-warmest January on record.

The warm readings were also reflected by the lack of snow cover across the country, reported as the third-lowest in the 46-year satellite record. Warmth — along with unusual weather events including spring-like tornadoes — were widespread across the country, as nine states reported top-ten January temperatures. Continue reading

SUMMIT COUNTY — Planet Earth stayed warm in October, with combined average land and ocean-surface temperatures coming in at 1.04 degrees above the 20th century average, a reading that made it the 10th-warmest October on record, and the second-warmest for land surface temperatures alone, according to the global summary issued this week by the National Climatic Data Center.

On the whole, October 2011 was much warmer than normal compared with previous Octobers. On average, land areas across the Northern Hemisphere — where the majority of the Earth’s land mass is located — were the warmest on record for the month, at 2.32 degrees above the 20th century average.

Despite early snowfall in some parts of the Rockies and in the Northeast, northern Hemisphere snow cover extent during October was below average, ranking as the 15th smallest October snow cover extent in the 44-year period of record. The North America and Eurasian land areas both had below-average snow cover during the month.

And while global warming deniers were busy trumpeting Arctic sea ice growth, the fact is that the average Arctic sea ice extent in October was 23.5 percent below average for the month, ranking as the second smallest October extent since satellite records began in 1979. The extent was 2.19 million square kilometers (846,000 square miles) below average and 330,000 square kilometers (127,000 square miles) above the record low October extent set in 2007.

Climate: October temps above average again

Early season snowstorms aren’t a sign of global-warming slowdown

Average October temps across the country were nearly a full degree above average, but cooler than normal readings prevailed in Summit County.

By Summit Voice

SUMMIT COUNTY — Despite a record-setting Nor’easter — and to the likely frustration of cherry-picking global warming skeptics, who claim that global warming has stopped — October was another warm month across the United States, with the average at 0.9 degrees above the 1901-2000 average.

Eighteen states reported monthly temperatures readings above their long-term averages, while 11 states reported readings below the monthly average. In the Pacific Northwest , in the central and southern plains, and parts of the Midwest reported near average temperatures for October. Most of the states with below average readings were in the Southeast, which was the coolest region for the month, according to the monthly report from the National Climatic Data Center.
