NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures.

With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

NASA’s Goddard Institute for Space Studies (GISS) in New York, which analyzes global surface temperatures on an ongoing basis, released an updated report Tuesday on temperatures around the globe in 2013. The comparison shows how Earth continues to experience temperatures warmer than those measured several decades ago.

The average temperature in 2013 was 58.3 degrees Fahrenheit (14.6 Celsius), which is 1.1 F (0.6 C) warmer than the mid-20th century baseline. The average global temperature has risen about 1.4 degrees F (0.8 C) since 1880, according to the new analysis. Exact rankings for individual years are sensitive to data inputs and analysis methods.

"Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change," GISS climatologist Gavin Schmidt said. "While one year or one season can be affected by random weather events, this analysis shows the necessity for continued, long-term monitoring."

Scientists emphasize that weather patterns always will cause fluctuations in average temperatures from year to year, but the continued increases in greenhouse gas levels in Earth’s atmosphere are driving a long-term rise in global temperatures. Each successive year will not necessarily be warmer than the year before, but with the current level of greenhouse gas emissions, scientists expect each successive decade to be warmer than the previous.

Carbon dioxide is a greenhouse gas that traps heat and plays a major role in controlling changes to Earth’s climate. It occurs naturally and also is emitted by the burning of fossil fuels for energy. Driven by increasing man-made emissions, the level of carbon dioxide in Earth’s atmosphere presently is higher than at any time in the last 800,000 years.

The carbon dioxide level in the atmosphere was about 285 parts per million in 1880, the first year in the GISS temperature record. By 1960, the atmospheric carbon dioxide concentration, measured at the National Oceanic and Atmospheric Administration’s (NOAA) Mauna Loa Observatory in Hawaii, was about 315 parts per million. This measurement peaked last year at more than 400 parts per million.

While the world experienced relatively warm temperatures in 2013, the continental United States experienced the 42nd warmest year on record, according to GISS analysis. For some other countries, such as Australia, 2013 was the hottest year on record.

The temperature analysis produced at GISS is compiled from weather data from more than 1,000 meteorological stations around the world, satellite observations of sea-surface temperature, and Antarctic research station measurements, taking into account station history and urban heat island effects. Software is used to calculate the difference between surface temperature in a given month and the average temperature for the same place from 1951 to 1980. This three-decade period functions as a baseline for the analysis. It has been 38 years since the recording of a year of cooler than average temperatures.

The GISS temperature record is one of several global temperature analyses, along with those produced by the Met Office Hadley Centre in the United Kingdom and NOAA’s National Climatic Data Center in Asheville, N.C. These three primary records use slightly different methods, but overall, their trends show close agreement.

  1. When the geo-engineering goes away and we have ACCURATE data on the ‘climate’…get back to me. We can discuss this when the sky above my head is not filled with white goo being sprayed from the back of drone planes.
    I paid for water sampling before the spray and after. Aluminum and barium along with strontium were all over 500x their safety limit. But hey, I paid for science, not just surfed a website.

    1. Give me a break. Utter rubbish. Take your tin foil hat nonsense back to those forums where conspiracy theorists hang out.

  2. Here is the scoop, by a scientist who believes that we are altering the climate but points out how, and clearly. When we are faced with this amount of stupidity by the powers that be, the only option seems to me to be, doorstep reparations.
    Pointing out ‘climate scare’ followed by ‘peak this or that’ is counter productive. So for those believers in global warming, this one is for you…

  3. ” Software is used to calculate the difference between surface temperature in a given month and the average temperature for the same place from 1951 to 1980. This three-decade period functions as a baseline for the analysis..”

    When the top of the article says this

    “With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.”

    It is precisely this obfuscation which polarises any discussion about the climates of the earth.

    Garth Paltridge is an emeritus professor at the University of Tasmania and a fellow of the Australian Academy of Science.
    Says this

    “The problem is that climate research necessarily involves enormous resources, and is a game for institutions and organisations. Scepticism is an occupation for individuals. Things being as they are in the climate-change arena, scepticism by an individual within the system can be fairly career-limiting. In any event, most individual scientists have a conscience, and are reluctant to put their heads above the public parapet in order to propound a view of things that may be inherently unprovable.

    In short, there is more than enough uncertainty about the forecasting of climate to allow normal human beings to be at least reasonably hopeful that global warming might not be nearly as bad as is currently touted. Climate scientists, and indeed scientists in general, are not so lucky. They have a lot to lose if time should prove them wrong.”

    Perhaps Garth can be contacted to see if he is willing to provide an article for the site?

  4. Hi Lance. Unfortunately for you, other people, like myself actually inhabit the real world which has real weather related events. 2013 was the hottest year in Australia’s history and the records here date back to 1870. Having been through 3 heatwaves within 12 months (one of which broke all previous records), your comment comes across as an Internet troll when read by people who are actually practicing agricultural techniques in that real world. Stop blaming some elite group who have some mythical agenda and start looking at how your own life and choices are contributing to the problem.

    Hi Bill. You completely fail to understand the article. It is not an article about forecasting, but showing what actually has happened in the recent past.

    1. Chris
      It is indeed an article about what happened in the recent past at the location where the records were physically recorded be that in a book by a human observer or by a machine.
      The location of these stations changes over time as does the local environment around them. This proves there isn’t 134 years of continuity in the record in the same location which is where the obfuscation comes in. It is written to give the impression the length of time validates the records.

      I used the Garth quote to illustrate how uncertain climate scientists are about the science that is all.

      As for Australia’s ‘Hottest ever year’ claims. Do click through on all of the links on this page it is fascinating.

      https://trove.nla.gov.au/ndp/del/article/125833141?searchTerm=hottest%20years&searchLimits=

    2. https://en.wikipedia.org/wiki/Precession https://en.wikipedia.org/wiki/File:Holocene_Temperature_Variations.png and finally https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=5003186.PN.&OS=PN%2F5003186&RS=PN%2F5003186 NASA creates extreme weather events through cloud seeding, coupled with the natural procession of the earth, and shifting climatic conditions creates a facade of impending doom to which NASA has the answer right? The answer is to block the sun with solar reflection and seeded cloud cover. Great, but what does that do for farmers and ther crops? Makes it really wet when you don’t want it, really dry when it’s not needed and blocks the sun which makes things grow. Why?

  5. In the real world of the PNW of North America we have been sprayed pretty much non-stop since 1998. But hey, I look up and analyze now and then, pulling my head out of the sand is refreshing. You can also use, I presume, a search engine?
    Look up ‘atmospheric aerosol spraying’. It’s not hidden.

  6. yeah and my dads bigger than your dad bla,bla,blaaaaa.
    come on PRI stop with this nonsense!.
    peace love & dirty fingers x

  7. Do you people realise how weird you sound? So your basic theory is that global warming is a result of cloud seeding experiments or have I got that wrong? How does that explain rising temperatures in parts of the world that obviously don’t have cloud seeding programs going on? No one cloud seeds in central Australia and nor could any country possibly afford to.

    I guess believing in conspiracies helps you sleep soundly at night, whilst at the same time burning propane which incidentally releases further greenhouse gasses into the atmosphere.

    Look. It is disrespectful to completely ignore my point that last year was the hottest year on record, temperature records were and are still being broken across the country, ignore the general content of the article and then bang on about your favourite soothing lullaby. Disappointing.

  8. “Possible causes [for the Permian-Triassic extinction event] supported by strong evidence appear to describe a sequence of catastrophes, each one worse than the previous: the Siberian Traps eruptions were bad enough in their own right, but because they occurred near coal beds and the continental shelf, they also triggered very large releases of carbon dioxide and methane. The resultant global warming may have caused perhaps the most severe anoxic event in the oceans’ history: according to this theory, the oceans became so anoxic, anaerobic sulfur-reducing organisms dominated the chemistry of the oceans and caused massive emissions of toxic hydrogen sulfide.” ~ Wikipedia

    If some of that sounds familiar, it should, and we could very well be sitting on a climate-change time-bomb… If anyone’s cloud-seeding/geo-engineering/etc., it could be out of some desperation…
    And then there’s the Law of Unintended Consequences…
