Earth Experiences 2nd Warmest Year to Date

Posted by feww on June 20, 2017

2nd warmest year to date and 3rd warmest May on record

Year to date – January through May 2017

The year-to-date (January–May) globally-average temperature across land and ocean surfaces for 2017 was 0.92°C (1.66°F) above the 20th century average of 13.1°C (55.5°F). This was the second highest January–May period in the 138-year record, falling behind the record year 2016 by 0.17°C (0.31°F).

May 2017 saw the average global temperature rising 0.83°C (1.49°F) above the 20th century average of 14.8°C (58.6°F) and the third highest May in the 138-year global records, behind 2016 (+0.89°C / +1.60°F) and 2015 (+0.86°C / +1.55°F), according to researchers at NOAA’s National Centers for Environmental Information.

Warmer-than-average lands and oceans

The globally averaged land-surface temperature (seventh warmest for the month of May) and the sea-surface temperature (third warmest) ranked second highest on record for the March-to-May season and the year to date.

Both poles recorded below-average sea ice again

The average Arctic sea ice extent for May dropped 5.3 percent below the 1981-2010 average, the fifth smallest for the month since satellite records began in 1979. The average Antarctic sea ice extent was 10.6 percent below average, the second smallest on record for May behind 1980.

 

SST

The average May temperature for the global oceans was 0.71°C (1.28°F) above the 20th century average of 16.3°C (61.3°F). This was the third highest May global ocean temperature in the 138-year record, trailing behind 2016 (+0.76°C / +1.37°F) and 2015 (+0.72°C / +1.30°F).

LST

The global land-only surface temperature was the coolest May land temperature since 2011 and the seventh highest since global records began in 1880 at 1.15°C (2.07°F) above the 20th century average 11.1°C (52.0°F).

Portugal [Apocalyptic Fires Incinerate Victims Fleeing in their Cars]

Unusually warm temperatures engulfed Portugal during May 2017. Portugal’s national average mean temperature was 18.47°C (65.25°F) or 2.74°C (4.93°F) above average—the third highest May temperature since national records began in 1931, trailing behind 2011 and 2015. The nation’s average maximum temperature was 24.96°C (76.93°F), which is 4.0°C (7.2°F) above average and the second highest May maximum temperature since 1931.

Northern Hemisphere Ice Cover falls below 3.6 million km² —FIRE-EARTH 

As of September 5, 2011, the Arctic sea ice extent (ASIE) was 3,686,199.43 km² according to NSIDC.

  • Daily average ice melt for September currently stands at more than 87,000 km², NSIDC data shows.

Arctic sea ice extent fell below 3.6 million square kilometers (1.39 million square miles) on September 6, 2012, FIRE-EARTH estimates.

FEWW model shows the Arctic sea ice extent could fall to about 3 million km² (1.15 million square miles) during the 2012 melt season with a probability of 0.5 [P = 54%]

Arctic Sea Ice Extent Rapidly Decreasing

Posted by feww on August 21, 2012

Northern Hemisphere sea ice extent drops below 4.5 million km²: FIRE-EARTH

FIRE-EARTH estimates the Northern Hemisphere sea ice extent dropped below 4.5 million km² on August 19, 2012.

A week earlier (August 13, 2012), the Northern Hemisphere sea ice extent was 5.09 million square kilometers (1.97 million square miles), which was 2.69 million km² below the 1979 to 2000 average extent for the date, and 483,000 km² below the previous record low set in 2007, according to the National Snow and Ice Data Center (NSIDC).

FEWW model shows the Arctic sea ice extent could fall below 3.8 million km² during the 2012 melt season with a probability of 0.7 [P≥65%]

Arctic ice cover shrank to a new record low of 4.28 km² in 2007, about 23 percent below the previous record set in 2005 and almost 40 percent lower than the 1979 – 2000 average.

The graph above shows Arctic sea ice extent as of August 13, 2012, along with daily ice extent data for the previous five years. 2012 is shown in blue, 2011 in orange, 2010 in pink, 2009 in navy, 2008 in purple, and 2007 in green. The gray area around the average line shows the two standard deviation range of the data. Source: NSIDC

“The average pace of ice loss since late June has been rapid at just over 100,000 square kilometers (38,000 square miles) per day. However, this pace nearly doubled for a few days in early August during a major Arctic cyclonic storm,” said NSIDC.

2010 Tied For Warmest Year on Record: NOAA

Posted by feww on January 13, 2011

2010 joint warmest and  wettest year on record

Last year tied with 2005 as the warmest year on record for global surface temperature

  • The 2010 global land surface temperature were 0.96ºC (1.73º F) above the 20th century average.
  • Global ocean surface temperatures in 2010 tied with 2005 as the third warmest at 0.49ºC (0.88ºF ) above the 20th century average.
  • 2010 was also the wettest year on record, compared to global average precipitation.

Highlights from NASA Climate Section:

  • September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average. The September 2010 extent was the third lowest in the satellite record.
  • As of December 10, 2010, the CO2 concentrations in the atmosphere were 391 ppm.
  • Data from NASA’s Grace satellite show that the land ice sheets in both Anarctica and Greenland are losing mass. The continent of Antarctica (left chart) has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002.
  • Sea levels have risen by 53mm since 1993, and by 100 to 200mm since the past century. Sea rise is caused by the thermal expansion of sea water due to climate warming and widespread melting of land ice.

“2010 tied with 2005 as the warmest year of the global surface temperature record, beginning in 1880. This was the 34th consecutive year with global temperatures above the 20th century average. For the contiguous United States alone, the 2010 average annual temperature was above normal, resulting in the 23rd warmest year on record,” NOAA researchers say.

  • Combined global land and ocean annual surface temperatures for 2010 tied with 2005 as the warmest such period on record at 1.12 F (0.62 C) above the 20th century average. The range of confidence (to the 95 percent level) associated with the combined surface temperature is +/- 0.13 F (+/- 0.07 C).*
  • The global land surface temperatures for 2010 were tied for the second warmest on record at 1.73 F (0.96 C) above the 20th century average. The range of confidence associated with the land surface temperature is +/- 0.20 F (+/- 0.11 C).
  • Global ocean surface temperatures for 2010 tied with 2005 as the third warmest on record, at 0.88 F (0.49 C) above the 20th century average. The range of confidence associated with the ocean surface temperature is +/- 0.11 F (+/- 0.06 C).
  • In 2010 there was a dramatic shift in the El Niño-Southern Oscillation (ENSO), which influences global temperature and precipitation patterns — when a moderate-to-strong El Niño transitioned to La Niña conditions by July. At the end of November, La Niña was moderate-to-strong.
  • According to the Global Historical Climatology Network, 2010 was the wettest year on record, in terms of global average precipitation. As with any year, precipitation patterns were highly variable from region to region.
  • The 2010 Pacific hurricane season had seven named storms and three hurricanes, the fewest on record since the mid-1960s when scientists started using satellite observations. By contrast, the Atlantic season was extremely active, with 19 named storms and 12 hurricanes. The year tied for third- and second-most storms and hurricanes on record, respectively.
  • The Arctic sea ice extent had a record long growing season, with the annual maximum occurring at the latest date, March 31, since records began in 1979. Despite the shorter-than-normal melting season, the Arctic still reached its third smallest annual sea ice minimum on record behind 2007 and 2008. The Antarctic sea ice extent reached its eighth smallest annual maximum extent in March, while in September, the Antarctic sea ice rapidly expanded to its third largest extent on record.
  • A negative Arctic Oscillation (AO) in January and February helped usher in very cold Arctic air to much of the Northern Hemisphere. Record cold and major snowstorms with heavy accumulations occurred across much of eastern North America, Europe and Asia. The February AO index reached -4.266, the largest negative anomaly since records began in 1950.
  • From mid-June to mid-August, an unusually strong jet stream shifted northward of western Russia while plunging southward into Pakistan. The jet stream remained locked in place for weeks, bringing an unprecedented two-month heat wave to Russia and contributing to devastating floods in Pakistan at the end of July.
