Latest Data Shows Global Climate Continues Warming Trend

21 Jan , 2014 by

The latest statistics are in from 2013 and both NASA’s and NOAA’s measurements of global temperatures show Earth continued to experience temperatures warmer than those measured several decades ago.

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, while NOAA – which uses a different method of analyzing temperature data – said that 2013 tied with 2003 as 4th-warmest year globally since 1880.

“The long-term trends are very clear, and they’re not going to disappear,” said climatologist Gavin Schmidt from NASA’s Goddard Institute for Space Studies (GISS). “It isn’t an error in our calculations.”

Land and ocean global temperatures in 2013 from both NASA and NOAA. Via NASA.

NASA data shows that since 1950, average temperatures have increased 1.1°F to an average of 58.3° in 2013.

NOAA data shows the average temperature across global land and ocean surfaces was 1.12 degrees above the 20th-century average. This is the 37th consecutive year that the annual temperature was above the long-term average.

This coincides with another recent study that showed the so-called “pause” in global warming is not happening, and that the temperatures over the past 15 years are still on the rise.

Both NASA and NOAA scientists say the increase in greenhouse gas levels continue to drive the temperature increase.

Additionally, 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 says 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.

More from NASA:

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.

Yes, warming continues and good, single source, long term data (Greenland and Antarctic ice core) supports that statement for last 200 years or so… What we and author forget is to ask are 2 crucial questions (maybe even 3): 1) From what temperature level have this warming started? – Same trusted, published, peer reviewed sources supporting 200 years of warming say… from the coldest period in last 10000 years. Also known as a “Little Ice Age”. Not from some long term average. From the coldest temperatures in human history. 2) OK, but we are warming up for 200 years, aren’t we now in a very hot period? – Same trusted, published, peer reviewed sources supporting 200 years of… Read more »

GISP2 records ended in1855 (1950 was year zero).
In the past, the 1,050 year cycle peak was ~16 years long.
It has split in 2, conductions have changed.
Indicating end of interglacial effects, the 4,500 year cycle is missing.
It is an inter-modulation problem – more complex than a diode mixer.

GISP2 data ends at 1905 – year 0 is 2000 AD: http://www.ncdc.noaa.gov/paleo/metadata/noaa-icecore-2475.html – if you read the paper there’s 1% uncertainty, bear in mind it’s reconstructed – the newest NASA/NOAA results show almost 1 degree C in around 60 years, whereas GISP2 show around 0.5 degree in 200 years since the little ice age, seems we are warmer than the middle ages now, hence our growth – if you want to go further back, are you just relying on GISP2, what about other measurements? Anyway, if its not hot enough where you are, you can move to warmer parts of the world, see if it makes you more productive…

“GISP2 data ends at 1905” — Someone quoted an email from Alley stating that year Zero was 1950 — there are several others claiming that 1855 is the last data year.

Would be interesting to correlate several previous
Vostok inter-glacials, to determine nonlinear mixing.
(similar to a diode producing harmonics and intermod)

Here in Sweden we are lowering the piers where passenger ferrys dock. There has been too many incidents where people break their legs when they are jumping from the piers into the ferry. When the piers were made about 100 years ago the were level with the decks of the ferry. (The ferrys are the same and kept as sort-of museums for nostalgic reasons). But pay no attention to this minor discrepancy between myth and reallity…

If you have an archipelago, and one island is disappearing, the most likely thing is that the island is sinking. It happens all the time. It is VERY unlikely, to say the least, that the water is rising around that island only, don’t you agree? If you don’t, try to make a hill of water in your bathtub.

There are hundres or thousands of coral reefs in the pacific that extends just a few feet above the surface. They seem to do just fine, and people are building hotels and airports on some of them.

All the available records show that Sea levels are on the rise since 100 years ago. It has risen by 6 inches in the last 100 years. So these Docks in Sweden if they were built 100 years ago, then the sea level then would have been 6 inches (15 cm) lower. No doubt such a small change would not account for “too many incidents where people break their legs when they are jumping from the piers into the ferry” There is something called “Tides”, a seasonal change of Sea level brought on by gravitational pull of the Moon. To use that line about people breaking legs to say that 100 years ago the Sea levels were higher… Read more »

Actually, all avaiable records show that the sea levels has been rising for the last 20 000 years. The reason we have to lower the piers in sweden is land rise. Sweden has been rising relative to the sea level about 90 cm the last century. This combined with a high pressure over Stockholm and boarding the “Djursholm ferry” becomes a dare devil act. My point is that “sea level change” is a little bit more complicated than what you may have thought.

I used to be a firm believer in man-made global warming, now I have some doubts. Where I live, it was the 4th coldest summer since records started, Alaska had their shortest and coldest summer on record, both poles are experiencing record ice sheet coverage, and globally, there were more cold records set in 2013, than warm records set. So, after all that is considered, how can it be that the year was one of the warmest ever? It makes no logical sense.
