FRISCO — For all the tweeting, squawking and general clamor from global warming deniers, you’d think the Earth was on the brink of a new ice age, but the facts show otherwise.

Once again during September, the average global temperature was near record highs, at 1.15 degrees above the 20th century average — tied with 2003 as the fourth-warmest on record.

Even without the warming effect of El Niño, the average global ocean temperature was .97 degrees above the 20th century average, tying with 2006 as the fourth-warmest on record. For the year, land and sea surface temperatures together are on pace to register as the sixth warmest on record, according to the National Climatic Data Center, which released its monthly climate update a few days late due to the shutdown.

Climate: August 2013 tied as 4th-warmest ever

Record-warm sea surface temps reported in higher latitudes


Most parts of the globe saw well above average temperatures in August 2013.

By Summit Voice

FRISCO — Global land and sea surface temperatures were both well above average in August 2013, with the month ending in a tie with 2005 as the fourth-warmest August on record, dating back to 1880.

According to the NOAA National Climatic Data Center’s monthly summary, it was the 35th consecutive August with global temperatures running above average.

Land surface temperatures were 1.39 Fahrenheit degrees above average, making it the 11th-warmest August on record, while the global sea surface temperature was 1.03 degrees Fahrenheit above average, tying with 1998, 2003, 2005, and 2009 as the record-highest for August. Continue reading

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

Climate: July global temps 6th-warmest on record

Year-to-date readings also rank as 6th-warmest


A NASA global temperature map for July shows the widespread pattern of above-average land and sea surface temperatures.

By Summit Voice

FRISCO — The global temperature for July 2013 was 1.10 degrees (all temperatures in Fahrenheit) above the 20th century average, making it the sixth-warmest July on record, according to the National Climatic Data Center.

Nearly every part of Earth reported temperatures well above average with the exception of a few pockets, notably the southeastern and central U.S. and parts of India.

The year to date (January-July) is also ranked as the sixth-warmest on record, with the global land surface temperatures running 1.73 degrees above the 20th century average. Continue reading

Climate: From drought to deluge



Climate experts outline weather extremes across the U.S.

By Bob Berwyn

After years of persistent drought across big swaths of contiguous 48 states, the weather picture changed dramatically in 2012. Instead of dealing with parched ground, farmers in the Southeast weren’t able to harvest crops this summer because of standing water in the fields.

Mold and fungal diseases were reported across the region, particularly on crops such as corn, tomatoes and peanuts. The excess moisture has degraded the quality and flavor of many crops, including watermelons, tobacco, and peaches. Flooded soil  has hampered the growth of cotton and corn, with damage from excess moisture expected to cost billions, The National Climatic Data Center reported this week in its July update.

By Summit Voice

FRISCO — Although a big slice of the south-central and southeastern U.S. reported cooler-than-average temperatures in July, the contiguous 48 states as a whole were once again warmer than the 20th century average.

For the month, the National Climatic Data Center reported that the average temperature was 74.3 degrees across the lower 48 states, which 0.8 degrees above average. Continue reading

Global climate report for 2012 full of warning signs

Strongest climate signals coming from Arctic and extreme weather events


Many parts of the globe reported record and near-record temps in June 2013.

By Bob Berwyn

FRISCO — Some of the most compelling signs of global warming impacts continued to come from the Arctic in 2012, where sea ice extent reached a record low and Greenland experienced record surface melting last summer.

Another worrying sign is the warming in permafrost regions, where significant thawing could release a new surge of heat-trapping greenhouse gases that would intensify warming.

The average global temperature for the year was among the top-10 warmest on record, and other climate observations also are consistent with what to expect in a warming world, according to climate experts who released the 2012 State of the Climate report this week. Continue reading
