Posted by feww on January 9, 2016

Record December elevated 2015 to 2nd warmest year for US 48  —NOAA

The 2015 annual average U.S. temperature was 54.4°F (12.4°C), 2.4°F above the 20th century average, the second warmest year on record.

  • Warmest year for U.S. was  2012  with an average temperature of 55.3°F.
  • 2015 was the 19th consecutive year the annual average temperature exceeded the 20th century average.

The average contiguous U.S. precipitation was 34.47 inches (87.55cm), 4.53 inches above average, and ranked as the third wettest year in the 121-year period of record.

  • Only 1973 and 1983 were wetter.
  • The national drought footprint shrank about 10 percent last year.

Ten weather and climate disaster events with losses exceeding $1 billion each occurred  across the United States in 2015. These events included

July Warmest Month Ever Recorded Globally

Posted by feww on August 21, 2015

2015 the hottest year on record (so far)

Global: The combined average temperature over land and ocean surfaces for July 2015 was the highest since record-keeping began 136 years ago. At 0.81°C (1.46°F) above the 20th century average of 15.8°C (60.4°F), it surpassed the previous record set in July 1998 by 0.08°C (0.14°F), said NOAA.

As July is climatologically the warmest month of the year globally, this monthly global temperature of 16.61°C (61.86°F) was also the highest among all 1627 months in the record that began in January 1880. The July temperature is currently increasing at an average rate of 0.65°C (1.17°F) per century.

  • July average temperature across global land surfaces was 0.96°C (1.73°F) above the 20th century average, making it the sixth warmest July on record.
  • Global sea surface temperature in July was 0.75°C (1.35°F) above the 20th century average of 16.4°C (61.5°F), the highest departure not only for July, but for any month on record. The 10 highest monthly departures from average for the oceans have all occurred in the past 16 months (since April 2014).

The first seven months of 2015 were the warmest such period on record for global land and ocean surfaces, at 0.85°C (1.53°F) above the 20th century average, surpassing the previous record set in 2010 by 0.09°C (0.16°F).

  • Five months this year, including the past three, have been record warm for their respective months. January was the second warmest January on record and April third warmest.
  • The average global sea surface temperature of +0.67°C (+1.21°F) for the year-to-date was the highest for January–July in the 136-year period of record, surpassing the previous record of 2010 by 0.06°C (0.11°F). The average land surface temperature of +1.34°C (+2.41°F) was also the highest on record, surpassing the previous record of 2007 by 0.15°C (0.27°F).

Nine of the 10 warmest months since records began in 1880 (1,627 months ago) have occurred since 2005, reported NOAA.

Selected National Temperature Highlights

The UK experienced its warmest July day ever on July 1, 2015 when temperatures climbed to 36.7°C near London, UK Met Office reported.

Austria recorded its hottest July since national records began in 1767. The average temperature was 3.0°C (5.0°F) higher than the 1981–2010 average, beating the previous record of +2.7°C (+4.9°F) set in 2006.

  • Temperature reached a high of 38.2°C (100.8°F) in Innsbruck, highest in recorded history, on July 7th.

France had its third warmest July in its 116-year period of record, with the overall temperature climbing 2.1°C (3.8°F) above the 1981–2010 average. Localized departures of more than 4°C (7°F) were recorded in the Massif Central to the North East and the Alps, said MeteoFrance.

Middle East experienced one of the most extreme heat indices ever recorded anywhere on July 31st, due to a high pressure dome that resided over the region.  The city of Bandar Mahshahr, Iran, recorded the air temperature of 46°C (115°F) together with a dew point of 32°C (90°F) resulting in a heat index of 74°C (165°F). The highest recorded heat index of 81°C (178°F) was in Dhahran, Saudi Arabia on July 8th, 2003.

Posted by feww on February 21, 2015

For the Record:

Arctic sea ice extent for January 6.3 percent below 1981–2010 average

The globally averaged temperature over land and ocean surfaces last month was 0.77°C (1.39°F) above the 20th century average, the second highest for January since record keeping began in 1880, said the National Climatic Data Center (NCDC).

[The warmest January on record was in 2007, at 1.55°F (0.86°C) above average.]

Other Global Highlights:

  • The globally-averaged land surface temperature was 2.57°F (1.43°C) above the 20th century average, making it also the second highest on record for January. The warmest January was in 2007, at 3.31°F (1.84°C) above average, while sea surface temperature (SST) was 0.95°F (0.53°C) above average— the third highest for January.
  • The average Arctic sea ice extent for January was just over 906,000km² (350,000 square miles) or 6.3 percent below the 1981–2010 average, making it the third smallest January extent since records began in 1979.
  • Antarctic sea ice during January was 2,300,000km² (890,000 square miles), or 44.6 percent above the 1981–2010 average, making it the largest January extent on record, surpassing the previous record set in 2008 by 570,000km² (220,000 square miles) or 33 percent.

The latest data show that 14 of the 15 warmest years on record have occurred this century.

2001-2010 was the warmest decade on record.

The Atmospheric Temperatures

Two different analyses examined NOAA satellite-based data records for the lower and middle troposphere and the lower stratosphere.

  • The 2014 temperature for the lower troposphere (roughly the lowest five miles of the atmosphere) was third highest in the 1979-2014 record, at 0.50°F (0.28°C) above the 1981–2010 average, as analyzed by the University of Alabama Huntsville (UAH), and sixth highest on record, at 0.29°F (0.16°C) above the 1981–2010 average, as analyzed by Remote Sensing Systems (RSS).
  • The 2014 temperature for the mid-troposphere (roughly two miles to six miles above the surface) was third highest in the 1979–2014 record, at 0.32°F (0.18°C) above the 1981–2010 average, as analyzed by UAH, and sixth highest on record, at 0.25°F (0.14°C) above the 1981–2010 average, as analyzed by RSS.
  • The temperature for the lower stratosphere (roughly 10 miles to 13 miles above the surface) was 13th lowest in the 1979–2014 record, at 0.56°F (0.31°C) below the 1981–2010 average, as analyzed by UAH, and also 13th lowest on record, at 0.41°F (0.23°C) below the 1981–2010 average, as analyzed by RSS. The stratospheric temperature is decreasing on average while the lower and middle troposphere temperatures are increasing on average, consistent with expectations in a greenhouse-warmed world.

2012 one of 10 warmest years on record globally

Posted by feww on August 7, 2013

The following excerpts are from ‘State of the Climate in 2012,’ a 2-dimentional annual report prepared by the American Meteorological Society (AMS), with researchers from NOAA’s National Climatic Data Center in Asheville, NC acting as lead editors.

Earth more rapidly warming since 1970: Report

Since 1976, the earth has experienced annual temperatures above the long-term average. The rate of warming is 0.06°C (0.11°F) per decade since 1880 and a more rapid 0.16°C (0.28°F) per decade since 1970, according to the 2012 annual report from NOAA’s National Climatic Data Center.

globalsurfacetemp_1880-2012_NOAA
Earth’s average annual surface temperature is higher today than it was when record keeping began more than a century ago. The red line shows how far above or below the 1981–2010 average (dashed line at zero) the combined land and ocean temperature has been each year since 1880. The data shown are from NOAA’s National Climatic Data Center, one of several temperature analyses included in the State of the Climate in 2012, all of which show a similar warming trend. Graph adapted from Figure 2.1, in BAMS State of the Climate in 2012.

The largest of warm anomalies in 2012 were observed across the Northern Hemisphere higher latitudes: The United States,  Canada, southern Europe, western Russia and the Russian Far East, said the report.

Sea levels reached record highs in 2012. Globally, sea level has been increasing at an average rate of 3.2 ± 0.4 mm per year over the past two decades.

The global surface temperature ranked among the top 10 warmest years on record. Over land and ocean combined, 2012 was between 0.14° and 0.17° Celsius (0.25°and 0.31° Fahrenheit) above the 1981–2010 average, depending on the analysis. The globally averaged annual temperature over land was 0.24°–0.29°C (0.43°-0.52°F) above average. And averaged globally, the 2012 ocean temperature was 0.10°–0.14°C (0.18°-0.25°F) above average.

U.S. Warmer, Drier in March

Posted by feww on April 11, 2010

Despite the appearances ‘U.S. Averaged Warmer-than-Normal, Drier-than-Normal in March’

According to NOAA’s State of the Climate report the March 2010 average temperature for the contiguous United States was warmer than average.

Thirteen states recorded an average temperature that was among their 10 warmest ever for March:

  • Rhode Island experienced its warmest March on record;
  • Maine its second warmest for the month
  • New Hampshire its third warmest

Again, despite the appearances, average precipitation for the U.S. was below normal, but heavy rainfall in parts of the Northeast set March records.

NOAA’s monthly temperature analysis are based on data recorded since 1895.

Temperature Highlights for March 2010

  • March temperature average across the contiguous United States was 44.4 degrees F, some 1.9 degrees F above the long-term average. “However, several storms developed along the Atlantic Coast, bringing below-normal temperatures to the South and Southeast, while bringing warm and wet weather to the Northeast and Midwest regions (Illinois, Indiana, Michigan, Ohio and Wisconsin).”
  • Thirteen states averaged temperature among their 10 warmest for March.
  • Gulf Coast states, New Mexico, Georgia and South Carolina experienced cooler-than-normal temperatures. Florida recorded its fourth coolest March.
  • January-March period
    • Maine, Vermont and New Hampshire: Warmest ever
    • Florida: Coldest ever
    • Louisiana: Second coldest
    • Mississippi and Alabama : Third coldest

Precipitation Highlights for March 2010

  • Average March precipitation  across the contiguous United States fell below the long-term mean (LTM). The month’s national average fell 0.24 inches below the LTM of 2.16 inches. “The Northeast was above-normal, while much of the interior United States was below-normal. All other regions were near normal.”
  • January – March period
    • Massachusetts, Rhode Island and New Jersey:  Wettest on record
    • Delaware: Second wettest on record
    • Vermont:  Fifth wettest
    • Twenty other states:  Precipitation ranked among the top 10 wettest.
    • Michigan:  Driest ever January-March period
    • Wisconsin: Fourth driest
    • Montana and Wyoming: Sixth driest.

Other Highlights

  • The preliminary tornado count for March was 36 – joint  4th quietest March since reliable records began in 1950,  NOAA’s Storm Prediction Center said.
  • Mid-March ice coverage over the Great Lakes was at a record low, covering only 3.5 percent of the Lakes’ surface, the Canadian Ice Service said.The average ice extent for the period was estimated at 31 percent of the Lakes’ surface. The records started in 1973.
  • Drought on March 30 covered about 9.0 percent of the United States, according to the U.S. Drought Monitor.
