Will Anybody Notice Global Cooling

By Norm Kalmanovitch, Friends of Science

It is inconceivable that even after a decade since global warming ended and seven years into a cooling trend with no end of cooling in sight, that world leaders are unaware of these facts and are still pursuing initiatives to stop global warming. Something is terribly wrong with the official international science bodies such as the IPCC who have not come forward and properly informed the world leaders of current global temperatures.

Something is terribly wrong with the individual government science bodies who did not come forward and inform their own leaders when it was certain that global warming had ended, or when there was sufficient data to claim that we are now in a cooling trend. It is not as though this is highly guarded secret data that can only be accessed by a limited group of people. The global temperature data is in fact readily available from several public sites and can be downloaded at no cost.

For the past year Friends of Science has been maintaining a graph of satellite temperature data and atmospheric CO2 concentration data on their website. This graph is updated every month as the new data becomes available. The cooling trend that started in 2002 is highlighted by a straight line best fit posted on this graph. The numerical value for this trend is 0.25C/decade of cooling!

By contrast the forcing parameter of the IPCC climate models would dictate that the effect of the 10ppmv increase in CO2 should cause a temperature increase of 0.15C/decade.  If in fact there is any validity to the claims of CO2 increases causing warming; the fact that we are cooling at twice the rate that the climate models say we should be warming, is a clear indication that natural forces are about three times stronger than the maximum possible effects from CO2 increases.

Quantum physics clearly demonstrates that the effect of current increases in CO2 can have only a small and diminishing effect on global temperature with further increases in concentration. Since the natural effects dominate, and physics dictates that the effect of increasing emissions is only a small fraction of the effect commonly accepted; it is clear that any initiatives aimed at reducing CO2 emissions for the purpose of reducing global warming are entirely without merit and serve no purpose whatsoever.

This is not a trivial issue because these initiatives to stop global warming have caused great suffering to the poorest people of the world. Biofuel initiatives have caused a global food crisis as food crops were forced to compete with biofuel crops driving the price of basic food staples beyond the means of the poor. The attempt to replace inexpensive coal fired power plants with very expensive and unreliable alternate energy sources such as wind power, has raised the cost of power not only affecting the poor, but also industry further reducing the ability to compete with countries using inexpensive power to manufacture products.

Unfortunately the AGW concept is so engrained in the public psyche through the graphic propaganda of the last several years that all verbal arguments against this ideology fall on deaf ears, and get shouted down by an indoctrinated crowd. While these people are deaf they are not blind, and no matter how loud the shouting, a graphic representation of increasing CO2 and decreasing global temperatures will be seen above the din.

If every presentation contained a graph similar to the one on the Friends of Science website this “visual” will eventually get in front of leaders who will be forced to reconsider the global warming initiatives that have been so costly to the world.

Have Changes In Ocean Heat Falsified The Global Warming Hypothesis?

By William DiPuccio on Climate Science

The Global Warming Hypothesis

Albert Einstein once said, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” Einstein’s words express a foundational principle of science intoned by the logician, Karl Popper:  Falsifiability.  In order to verify a hypothesis there must be a test by which it can be proved false.  A thousand observations may appear to verify a hypothesis, but one critical failure could result in its demise.  The history of science is littered with such examples.

A hypothesis that cannot be falsified by empirical observations, is not science.  The current hypothesis on anthropogenic global warming (AGW), presented by the U.N.’s Intergovernmental Panel on Climate Change (IPCC), is no exception to this principle.  Indeed, it is the job of scientists to expose the weaknesses of this hypothesis as it undergoes peer review.  This paper will examine one key criterion for falsification: ocean heat.

Ocean heat plays a crucial role in the AGW hypothesis, which maintains that climate change is dominated by human-added, well-mixed green house gasses (GHG).  IR radiation that is absorbed and re-emitted by these gases, particularly CO2, is said to be amplified by positive feedback from clouds and water vapor.  This process results in a gradual accumulation of heat throughout the climate system, which includes the atmosphere, cryosphere, biosphere, lithosphere, and, most importantly, the hydrosphere.  The increase in retained heat is projected to result in rising atmospheric temperatures of 2-6C by the year 2100.

In 2005 James Hansen, Josh Willis, and Gavin Schmidt of NASA coauthored a significant article (in collaboration with twelve other scientists), on the “Earth’s Energy Imbalance:  Confirmation and Implications” (Science, 3 June 2005, 1431-35).  This paper affirmed the critical role of ocean heat as a robust metric for AGW.  “Confirmation of the planetary energy imbalance,” they maintained, “can be obtained by measuring the heat content of the ocean, which must be the principal reservoir for excess energy” (1432).

In 2007 Roger Pielke, Sr. suggested that ocean heat should be used not just to monitor the energy imbalance in the climate system, but as a “litmus test” for falsifying the IPCC’s AGW hypothesis (Pielke, “A Litmus Test”, climatesci.org, April 4, 2007).

A comparison of these projections to observed data is shown below.  Despite expectations of warming, temperature measurements of the upper 700m of the ocean from the ARGO array show no increase from 2003 through 2008.  Willis calculates a net loss of -0.12 (plus or minus 0.35) x 1022Joules per year (Pielke, Physics Today,55) from mid-2003 to the end of 2008 (Dr. Pielke received permission from Josh Willis to extend the ARGO data to the end of 2008).

According to a recent analysis of ARGO data by Craig Loehle, senior scientist at the Illinois-based National Council for Air and Stream Improvement, the loss is -0.35 (plus or minus 0.2) x 1022Joules per year from mid-2003 to the end of 2007 (see Loehle, 2009: “Cooling of the global ocean since 2003.” Energy & Environment, Vol. 20, No. 1&2, 101-104(4)).  Loehle used a more complex method than Willis to calculate this trend, enabling him to reduce the margin of error.

My calculations for observed global heat, shown below, are based on observed upper ocean heat.  Since upper ocean heat is calculated to be 80% of the global total, observed global heat equals approximately 125% (1/0.8) of the observed upper ocean heat.

AARI Predicts Arctic Cooling/Ice Recovery To Continue

By Joseph D’Aleo (h/t to Dr. Gary Sharp)

Arctic ice extent bottomed out in 2007, and has recovered the last two years as shown by this graph from the University of Illinois Cryosphere.

It has returned to very near the 1979-2000 year average (NSIDC). Had NSIDC used the entire period of record as their base period (1979-2008), we would be at or above the average.

The most competent polar scientific organization, Arctic and Antarctic Research Institute (AARI) in St. Petersburg, Russia published recently 3 books summarizing scientific results of climate changes in the Arctic region for the last century. One of it dedicated to Arctic climate. Based on the results obtained they forecast coming temperature and sea ice cover area changes in the Polar seas for the next 10-20 years.
Anomaly of mean annual air surface temperature 1900-2006 in the zone of 70-90 N and its predicted trend (I.E.Frolov et al. Scientific research in Arctic. Vol. 2. Climatic changes in the ice cover of the Eurasian shelf seas. -SPb.: “Nauka”, 2007,158 p).

The authors showed that Arctic climate change is natural in origin and several orders of magnitude greater than the level of anthropogenic impact on the climate. Estimates of possible changes of Arctic air temperature and ice cover propagation area for the 21st century are given on a basis of the revealed stable cyclic oscillations of 10, 20 and 50 to 60 years.

Inconvenient Eisdicken - “surprising results” from the Arctic

By Anthony Watts, Watts Up With That

This is a news story from Germany outlining another Arctic ice measurement expedition. This one was conducted by flying the scientists across the north polar ice cap using the WWII era workhorse Douglas DC-3 airplane equipped with skis, and towing an airborne sounder twenty meters above the ice surface. It makes the Catlin Arctic Ice Survey look rather pointless, but then we knew that.  BTW “Eisdicken” translates to “ice thickness”. - Anthony

Surprising Results: At the North Pole ice sheet is thicker than expected.

The research aircraft Polar 5 ended today in Canada’s recent Arctic expedition.  During the flight, researchers have measured the current Eisstärke measured at the North Pole, and in areas that have never before been overflown. Result: The sea-ice in the surveyed areas is apparently thicker than the researchers had suspected.

Normally, ice is newly formed after two years, over two meters thick. “Here were Eisdicken up to four meters,” said a spokesman of Bremerhaven’s Alfred Wegener Institute for Polar and Marine Research. For scientists, this result is still in contradiction to the warming of the seawater.

Besides the Eisdicken was also the composition of the air are investigated. With the help of a laser, the researchers reviewed how polluted the atmosphere by emissions from industrialized countries. On the expedition, some 20 scientists from the U.S., Canada, Italy and Germany.

An ice thickness probe, the so-called EM-Bird, which is usually dragged below a helicopter, is now operated for the first time by a fixed-wing aircraft. The EM-Bird is towed under the hull of the aircraft by means of a winch for take-off and landing. For the surveys, the probe is towed on an 80 m long rope twenty metres above the ice surface. More extensive areas can now be investigated due to the longer range of the aircraft in comparison to a helicopter.

UPDATE: more on the EM-Bird probe (h/t to Ron de Haan)
Electromagnetic (EM) induction sounding for ice thickness measurements is a technique that can achieve long profiles of some kilometer length. The accuracy and robustness of the EM method has been evaluated by comparing coincident drill-hole and EM measurements.  Read more (Poster, pdf, size: 156 kB). Sure beats hauling a sledge and a broken home-built ice radar around doesn’t it? Read more and see comments on this successful scientific expedition here and the other PR driven, BBC hyped but failed Catlin expedition that is likely reaching an end 542 km short of their goal with failed equipment and frostbite and in a blizzard here. Do expect a press release touting a successful Catlin mission carried by the BBC.

Here by the way is the latest NSIDC ice trace approaching the normal.

And finally note we continue to track ahead of all the years in the AMSR-E record (starting in 2002) in the IJIS-JAXA web site here.

The Pacific Ocean’s Influence on Climate Change: How Low Will the PDO Go?

By Jeremy Ross, PhD

Long-term variations in ocean circulations produce pronounced patterns of sea surface temperature (SST) anomalies that directly impact weather and climate.  The most influential long-term oceanic cycle is the Pacific Decadal Oscillation (PDO), a large-scale phenomenon in the North Pacific that produces inter-decadal oscillations of cool and warm SST anomalies, with each phase typically lasting 20 to 30 years.  During the cool (negative) phase of the PDO, a large horseshoe-shaped area of cooler than average SST extends from the central equatorial tropics northeastward to the Mexican and U.S. coastlines, then northward along the Canadian and Alaskan coastlines.  During the warm (positive) phase the pattern is reversed with warm SSTs replacing the cool SSTs.  The Atlantic Ocean experiences a similar oscillation known as the Atlantic Multidecadal Oscillation (AMO) which has profound impacts on the number and intensity of Atlantic hurricanes as well as Arctic sea ice extent.

After a period of intense cooling in the 1950s, 1960s, and 1970s, the PDO returned to the positive phase during the late 1970s and remained generally positive through the late 1990s.  Since 1999, a transition into the cool phase has been underway, and during 2008 the transition was completed as recent observations of the coastal waters have been among the coolest in the past 109 years.

The average PDO index from April 2008 to March 2009 was -1.46, the third lowest yearly averaged March value since 1900, trailing only March of 1956 and 1951.  For the next two or three decades, North Pacific SST anomalies will favor the negative phase, and will likely produce exceptional climate patterns and weather events that have not been observed in more than three decades.

The strongly negative PDO was influential in shaping North American climate during the past year. In 2008, Anchorage, Alaska, recorded only 2 days above 70 degrees F, the least number of days to exceed 70 since records began in 1917.  The PDO strongly influenced the winter of 2008/2009 with dry conditions and warmth in the south central U.S. and snowy and colder than average temperatures in the Northern Plains.  Although the PDO will continue to be the dominant climate driver for the remainder of 2009, its impacts will subside during the summer when the atmospheric flow weakens and climate is more strongly affected by local influences such as land conditions and proximity to water bodies.
