A Climate Change Reality Check
  • One Persons Review of the State of Climatic
    Science, Specifically Anthropogenic (Human
    Produced) Greenhouse Gases versus Natural
    Climatic Variations

3
I. Introduction
  • The basis of this review is to ascertain if the
    evidence for anthropogenic climatic warming
    withstands scrutiny using the principles of the
    Scientific Method.

4
A Quick Review of The Scientific Method
  • The scientific method is the process by which
    scientists, collectively and over time, endeavor
    to construct an accurate (that is, reliable,
    consistent and non-arbitrary) representation of
    the world.
  • Recognizing that personal and cultural beliefs
    influence both our perceptions and our
    interpretations of natural phenomena, we aim
    through the use of standard procedures and
    criteria to minimize those influences when
    developing a theory.
  • As a famous scientist once said, "Smart people
    (like smart lawyers) can come up with very good
    explanations for mistaken points of view." In
    summary, the scientific method attempts to
    minimize the influence of bias or prejudice in
    the experimenter when testing a hypothesis or a
    theory.

5
The Scientific Method has four steps
  • 1. OBSERVATION and DESCRIPTION of a phenomenon or
    group of phenomena.
  • 2. FORMULATION of a HYPOTHESIS to explain the
    phenomena. In physics and in climatic science,
    the hypothesis often takes the form of a causal
    mechanism or a mathematical relation.
  • 3. USE of the HYPOTHESIS to PREDICT the existence
    of other phenomena, or to predict quantitatively
    the results of new observations.
  • 4. Performance of experimental TESTS of the
    PREDICTIONS by several independent experimenters
    and properly performed experiments.
  • If the experiments bear out the hypothesis it may
    come to be regarded as a theory or law of nature.
    If the experiments do not bear out the
    hypothesis, it must be rejected or modified. What
    is key in the description of the scientific
    method just given is the predictive power (the
    ability to get more out of the theory than you
    put in) of the hypothesis or theory, as tested by
    experiment. It is often said in science that
    theories can never be proved, only disproved.
    There is always the possibility that a new
    observation or a new experiment will conflict
    with a long-standing theory. (Wilson, E. Bright.
    An Introduction to Scientific Research,
    McGraw-Hill, 1952).

6
Example of The Scientific Method
  • Einsteins General Theory of Relativity
  • In 1905, while working at a Swiss Patent office
    Albert Einstein published four papers which would
    comprise the basis of the General Theory of
    Relativity, which he published in 1916. At first
    his papers were either ignored or heavily
    criticized as the established world of physicists
    were very skeptical of his theories. But his
    theories were tested, and proved to be correct.
  • The first major test was in 1919. His theory
    predicted that large gravitation bodies can
    deflect light. Astronomers made observations and
    found that sure enough during the 1919 solar
    eclipse, they could accurately measure the
    deflection of star light by the sun.
  • Einsteins theories are still being tested to
    this day, NASA currently has several satellites
    (GRACE, LAGEOS, and in the future LISA) in orbit
    testing gravitation effects as predicted by
    Einstein to a much finer degree than has
    previously been possible.
  • Proper testing of the hypothesis of anthropogenic
    climatic warming must be done in a similar
    fashion, and examine its predictions against
    actual data.

II. Radiative Balance of the Planet
  • The earth is warmed by infrared radiation that is
    absorbed from the sun (about 235 w/m2).
  • The infrared radiation is transmitted through the
    atmosphere and absorbed by the earths surface by
    varying amounts, due the varied nature of the
    surface (ocean, snow pack, ice, soil, rocks,
    varied vegetation, human structures, etc.).
  • Some of the infrared radiation that is not
    absorbed is reflected back into the atmosphere
    which eventually transmits it back into space.
  • The balance of infrared radiation absorbed and
    infrared radiation reflected and transmitted into
    space allows the earths surface to stay at the
    relatively narrow range of temperatures.
  • This balance is controlled by the earths
    atmosphere, through its circulation systems and
    precipitation systems.

8
Radiative Balance (Spencer, Roy F. web site)
9
Weather and Precipitation Systems
  • The earths atmosphere is a complex circulation
    system,controlled by the 2nd Law of
    Thermodynamics which states that any system will
    try to come to an equilibrium.
  • In the case of the atmosphere that means that
    because of the vastly different temperatures and
    pressures of the atmosphere from surface
    (troposphere) to outer edges of the atmosphere
    (ionosphere) the atmosphere is constantly trying
    to balance the heating and cooling extremes that
    the addition of solar radiation on the atmosphere
    creates.
  • Thus weather systems constantly move warm and
    cold air around in the atmosphere, with the
    associated precipitation and condensation of
    water vapor. The result is cold and warm weather
    fronts, low and high pressure systems, and rain,
    snow, wind and all the types of weather systems.
  • The most important of these is the effect of
    precipitation systems. The process of
    evaporating water and then condensing and
    precipitating water moves heat up and down in the
    atmosphere.

10
How Precipitation Systems Move Heat - Part I
  • The difference in temperature from one region to
    the next causes air currents (wind) to blow
    across the surface of the earth, picking up heat
    from the surface and moving it to somewhere else.
  • The heat transferred to the surface from the
    overlying air is either sensible (an increase in
    air temperature), or latent (water evaporated
    from the surface, adding water vapor to the air
    which contains the latent heat of vaporization).
  • Latent heat loss by the Earths surface through
    evaporation is the dominant method of cooling it.
    You feel this effect when a breeze blows over
    your skin. The breeze is taking heat from your
    body as the water on its surface evaporates into
    water vapor and is removed from your body.
  • At least 90 percent of the heat lost by water
    bodies (streams, lakes, oceans) is through energy
    required to evaporate water from surface. For
    land surface plants evaporate water through
    evapotranspiration. That is why forests feel
    cooler the heat of vaporization is being
    removed from them.

11
How Precipitation Systems Move Heat - Part II
  • As air accumulates water vapor and latent heat it
    tends to rise. As the warm air rises it reaches
    levels of the atmosphere that are too cool to
    keep all the water vapor in vapor form. Now at
    100 percent humidity some water vapor condenses
    releasing the latent heat and warming the upper
    parts of the atmosphere. This warming from
    condensational heating then causes the cloudy air
    parcels to continue to rise and condense more
    water vapor. This is how clouds and ultimately
    thunderstorms are formed.
  • If precipitation reaches the surface it
    represents solar energy that has been transferred
    from the surface to the upper atmosphere.
  • These columns of warm air force the dryer air
    around them to sink to fill the gaps left by the
    rising warmer air. This air as it is being
    forced downward warms the upper troposphere by
    emitting infrared radiation some of which is
    transmitted to outer space.

12
The Effect of Weather on Radiative Balance
  • If there were no precipitation and circulation
    systems and the transmitting effect of weather on
    heat and cold in the atmosphere the temperature
    on the surface of the earth would be about 140 F
    (based on a radiative heat model - Spencer, Roy
    F., 2008). The temperature would rapidly
    decrease with altitude and as low as 30,000 feet
    the temperature would be so cold that jet fuel
    would freeze or turn into a gel and make jet
    aviation impossible without more insulation and
    heating in fuel tanks.
  • Therefore precipitation systems on earth have the
    effect of being the earths air conditioning
    system, cooling the surface and transmitting the
    heat up and throughout the atmosphere. (Spencer,
    Roy F., 2008)

13
Present Day Composition of the Atmosphere
  • The atmosphere is made of a number of gases
    primarily nitrogen (76.55), oxygen (20.54),
    water vapor (1.96), and argon (0.91). Other
    gases include carbon dioxide (0.03) and the rest
    of the atmosphere (0.1) is composed of methane,
    nitrous oxide, sulfur dioxide, helium, and other
    noble gases and trace gases. This is the current
    percentage of gases in the atmosphere.

14
Past Composition of the Atmosphere
  • However current gas percentages have in no way
    been constant over geologic time, and have varied
    considerably. For instance geologic studies have
    indicated oxygen may have been as low as 15
    percent and as high as 30 percent of the
    atmosphere in the last 550 million years

15
Greenhouse Gases
  • The gases that primarily control the balance of
    infrared radiation absorbed and reflected are the
    greenhouse gases.
  • A greenhouse gas is defined as a gas that
    strongly absorbs and emits infrared radiation.
    The dominant greenhouse gases in the atmosphere
    are water vapor, carbon dioxide, and methane.
  • These and some of the minor other gases act as
    radiative blanket, causing the lower atmosphere
    to be warmer, and the upper atmosphere cooler.
    They do this by trapping more of the infrared
    energy that would be dissipated into outer space.
    Of these three, water vapor is by far the most
    important, causing over 95 percent of radiative
    absorbing or transmitting.

16
Carbon Dioxide Stability
  • From studies of the geologic record and
    associated indications of the composition of
    ancient atmospheres (in many cases by isotope
    studies and proxy measurements) , it has been
    determined the concentration of carbon dioxide
    has not been stable, but has also varied over
    geologic time.

17
CO2 in Geologic Time Howard, J.F. TPG 6/08
18
Additional CO2 Studies
19
The hypothesis of anthropogenic global warming is
based on the following concepts
  • Human activities have added carbon dioxide in the
    atmosphere by the use of carbon based fuels (oil,
    gas, wood, etc.).
  • The amount of carbon dioxide in the atmosphere is
    steadily increasing due to human use of carbon
    fuels.
  • The increase of carbon dioxide has caused a shift
    in the radiative balance of the earths
    atmosphere, resulting in an increase in the
    infrared energy retained by the atmosphere.
  • This retention of infrared radiation will be
    expressed by an increase in temperature in the
    lower and upper troposphere of the atmosphere, a
    general increase in atmospheric global
    temperatures, and by an associated increase in
    ocean temperatures globally due to natural
    circulation and equilibrium between the
    atmosphere and the ocean.
  • The described increases in global temperatures,
    lower and upper troposphere temperatures, and
    ocean temperature will be expressed by changing
    conditions on the surface of the planet such as
    warmer average temperatures per latitude,
    shrinking ice packs such as continental and
    alpine glaciers, and resulting rises in sea
    level. (Spencer, Roy F., 2008)

20
Computer Models of Earths Climate
  • Computer simulations of climate using
    mathematical representation of different aspects
    or parameters of the atmosphere are used to
    attempt to forecast long-term trends of the
    worlds climatic system. These models are very
    speculative in that the complexitiy of climatic
    systems do not allow accurate representation of
    most parameters. In most models several
    parameters, often cloud cover or solar radiation
    have to be given a constant value because of time
    and limitations of the computing power of the
    multiple processors used by the modelers. Each
    climate model can thus be very different as the
    modeler chooses which parameters to vary and the
    limits of the variation.

21
Climate Models Complexity
22
Key Assumptions for most Climate Models
  • Solar irradiance on the earth remains within a
    narrow range and can be considered a constant
    over time.
  • The historical record of concentrations of carbon
    dioxide in the atmosphere is best found in ice
    core data.
  • The primary greenhouse gases are water vapor,
    carbon dioxide, and methane. The global
    temperatures will reflect increases of carbon
    dioxide and methane.
  • Although water vapor is the primary greenhouse
    gas (95 percent of the greenhouse effect is by
    water vapor), its effects can be considered
    relatively constant except in its relationship to
    carbon dioxide and methane.
  • The effect of carbon dioxide alone on atmospheric
    warming is limited in that its ability to trap
    infrared radiation significantly decreases with
    concentration. Due to this property the doubling
    of carbon dioxide concentration alone will result
    in an increase of 1 degree Celcius in global
    temperature at most, assuming a completely static
    atmospheric model.
  • The effect of carbon dioxide is amplified by
    feedback mechanisms which cause other gases
    (particularly water vapor) to increase and thus
    increase the warming effect.
  • Ocean temperatures will change over time as the
    increase in heat in the atmosphere will be
    transmitted to the ocean.

23
Key Suppositions from most Climate Models
  1. With increase in carbon dioxide, the temperature
    in the atmosphere will increase with altitude
    from the surface in the troposphere to an
    altitude of about 9 to 12 kilometers, and then
    decrease with the thinning of the atmosphere.
    This is the key mechanism of the hypothesis of
    anthropogenic global warming that causes the
    enhanced warming of the atmosphere. Increase in
    carbon dioxide causes the mid and upper level of
    the troposphere to heat up, transferring heat to
    the surface instead of being radiated out into
    space.
  2. With increase in carbon dioxide the temperature
    of the oceans should also increase. This
    temperature increase is significant because the
    oceans hold much more mass then the atmosphere
    and thus can hold much more energy for feedback
    mechanisms (resulting in higher sea levels and
    more storms hurricanes it is speculated).
  3. With increase in carbon dioxide a positive
    feedback is predicted to occur with water vapor
    resulting in the increase of water vapor in the
    atmosphere and corresponding increase in
    temperature. Some modelers have stated that as
    the climate temperature increases the amount of
    this feedback could result in approaching a
    tipping point leading to catastrophic increase in
    atmospheric temperature.

24
Climate Model Parameters
  • These assumptions and suppositions are key in the
    modelers climatic predictions that anthropogenic
    increases in carbon dioxide will result in human
    induced climate change (global warming) leading
    to increases in global increases in temperature
    with resultant glacial and ice cap melting,
    increased and severity of atmospheric
    disturbances (storms), sea level increases, fauna
    and flora stress and even possibly catastrophic
    effects on the climatic system.
  • Each one of these assumptions and suppositions
    must withstand scientific method scrutiny in
    order for the hypothesis of anthropogenic warming
    to be considered valid, as with any hypothesis.

25
Assumptions The Role of Solar Radiation
  • Assumption Solar Radiation varies over a narrow
    range and can be considered a constant over time.
  • Astrophysicists tell us that sun irradiance
    varies according to distinctive cycles which are
    only poorly understood. The most frequent cycle
    is the 11-year sun spot cycle. This cycle has
    been tracked since the 1700s and is now between
    cycle Number 23 and Number 24. The chart on the
    next slide depicts this periodicity.

26
Solar Sunspot Cycle
27
Assumptions The Role of Solar Radiation
  • As can be seen from the previous chart solar
    radiation on the earth has been on upward trend
    the last two centuries. According to the
    Max-Planck Institute for Solar Studies the level
    of solar activity during the past 70 years is
    exceptional, and the previous period of equally
    high activity occurred more than 8,000 years
    agoduring the past 11,400 year Sun spent only of
    the order of 10 of the time at a similarly high
    level of magnetic activity and almost all were
    shorter than the present episode. Solanki, S.K.
    et.al. , Nature 10/28/04.
  • The next three charts show additional
    periodicities with sunspot and solar activity.
    Note the presence of the Maunder minimum between
    1600 and 1700 and its relation with global
    temperatures and finally a summary of the past
    3,000 years in global temperatures.

35
Summation Solar Activity
  • Sun spot activity and thus solar activity has
    been historically recorded by observation for
    1400 years. These observations have been
    confirmed by isotope studies.
  • The historical tracking of sun spots and global
    temperature have determined there is a strong
    correlation between them, although the mechanism
    is not entirely clear because the change in solar
    radiation is not sufficient to cause the degree
    in temperature change directly (using the
    radiative model method).
  • One current theory is that with decreased solar
    activity, the decrease in solar wind allows more
    cosmic rays from outside the solar system to
    penetrate the atmosphere, ionize nitrogen
    oxygen atoms and provide more nucleating site for
    cloud droplets, increasing cloud cover and
    reducing global temperatures. Thus an indirect
    feedback mechanism.
  • Recent measurements have determined the last
    three decades of sun activity has been
    exceptional, with the most sun spot and thus
    solar activity in the past 8,000 to 11,400 years
    (Solanski, S.K., et.al, Nature, 2004).
  • The increase and decrease in global temperature
    this past century correlates strongly with this
    change in solar activity.
  • The recent drop in global temperature also
    corresponds to the current quiescent state of the
    sun, as it switches over from sun spot cycle 23
    to 24.
  • Because of these facts, Climate models that
    assume the solar irradiance is a constant are
    seriously flawed and probably invalid.

36
Examination of Assumptions
  • Assumption Ice core data is the best
    measurement of carbon dioxide concentrations in
    the atmosphere.
  • The IPCC and global climate modelers use ice core
    data and the amount of carbon dioxide trapped in
    gas bubbles in the ice core to measure the
    concentrations of carbon dioxide in the
    atmosphere. This has been the standard practice
    of climatologists for the past several decades.
    From ice core data it is assumed the pre
    industrial Holocene era (8,000 to 10,000 years
    ago) show a carbon dioxide level of about 240
    ppmv (ppm by volume).
  • Modern carbon dioxide measurements are compared
    to the Mauna Loa observatory, which has been
    measuring carbon dioxide meticulously since 1958.
    The steady increase of carbon dioxide is assumed
    to be due to the use of carbon based fuel.

37
Mauna Loa Observatory Data
38
Evaluation of Carbon Dioxide Ice Core Data
  • Reliance on ice core data ignores 90,000 accurate
    chemical analysis of carbon dioxide in air made
    since 1812 using reliable chemical methods that
    usually achieved accuracy better than 3 percent.
    This data, when compiled, indicates carbon
    dioxide has had three maxima in the last 200
    years around 1825, 1857, and 1942 with the later
    over 400 ppm (Beck, 2007). This data was not
    taken from specific station points for the
    purpose of examining carbon dioxide levels over
    extended periods, but collected as part
    scientific studies or measurements for other
    purposes. But, when carefully evaluated, there
    is no reason to assume this data is not useful as
    a historical carbon dioxide record.
  • Evaluation of gases in ice core data indicate
    they are not a reliable record of carbon dioxide
    as the carbon dioxide tends to differentiate and
    diffuse in cold liquid water and diffuses by the
    Knudsen diffusion effect at drastic pressure
    changes such as experienced by deep ice cores
    which minimizes variations and reduces maximums
    (Hurd, 2006).
  • Comparison of ice core data with proxy estimates
    of carbon dioxide (such as fossil leaf stomata
    indices) indicate ice core data consistently
    undervalues carbon dioxide concentrations by at
    miminum 100 to 200 ppm (Jaworowski, Zbigniew,
    Science, 2007).

39
Carbon Dioxide Chemical Methods from Beck 2004

Carbon Dioxide Chemical Methods from Beck 2004
41
Summation Ice Core Data
  • Climate models assume the preindustrial carbon
    dioxide levels were around 240 to 260 ppmv, based
    on ice core data. They also assume that the
    latest Mauna Loa station data indicates that
    carbon dioxide has increased steadily to maximum
    values for the past 100 years.
  • Ice core data has been demonstrated to be
    unreliable and the Mauna Loa data ignores prior
    data collected before the station initiation that
    found carbon dioxide levels above 400 ppm this
    century.
  • Therefore the basic assumptions of the climate
    models regarding current and past carbon dioxide
    level that are based on ice core data are
    demonstratably underestimated and therefore
    suspect and probably invalid. Values of
    historical carbon dioxide levels require further
    independent verification by other proxy
    measurements or direct measurements if they can
    be developed.

42
Carbon Dioxide Increases and Global Temperatures
the past 200 years
  • Assumption The primary greenhouse gases are
    water vapor, carbon dioxide, and methane. The
    global temperatures will reflect increases of
    carbon dioxide and methane.
  • The climate models and most proponents of global
    warming postulate that the dramatic increase in
    the use of fossil fuels as part of the industrial
    revolution (particularly after the 1850s) have
    caused the amount of carbon dioxide to steadily
    increase. This increase will be reflected in
    global temperatures because of increases in
    greenhouse gases and the resultant affect on the
    radiative balance of the planet.

Comparison of Carbon Based Fuel Use and Global
Temperatures
  • 1. Comparison with use of carbon based fuel and
    global temperatures have found contradictory
    correlations for the past 150 years.
  • 2. Increase in global temperature from the 1910
    to 1940 compared to flat or small increase in
    carbon based fuels, and correlation was negative
    between 1940 to the late 1970s. Only positive
    correlation was after 1980s.
  • Sea level rise and glacier shortening demonstrate
    no correlation.
  • Solar activity actually correlates more closely.

Up to Date Temperature Trends

47
The Relationship of Carbon Dioxide and
Temperature over Geologic Time
  • Ice core data such as the Vostok ice cores have
    found that during the fluctuations of temperature
    that have occurred in the last 400,000 years,
    carbon dioxide values have increased and
    decreases in response to temperature changes, and
    have not been a driver of temperature changes.
  • Usually the maximum carbon dioxide concentration
    will follow a peak in temperature by about 400 to
    800 years.
  • The explanation for this is probably the oceans
    and other water bodies that contain carbon
    dioxide are outgasing this molecule as they warm,
    like a can of soda outgases its carbonation as it
    sits.

  • A positive global temperature correlation with
    increase in fossil fuel use is observable only in
    last 20 years of last century.
  • Comparison with beginning or middle part of
    century flat or negative.
  • Solar activity actually is a better fit for
    global temperature correlation.

Temp vs CO2 using Mauna Loa Data
51
Examination of Water Vapor Constant Assumption
  • Most climate models assume that as carbon dioxide
    is increased the temperature of the atmosphere
    will increase which will increase the evaporation
    of water adding more water vapor. As water vapor
    is a greenhouse gas this would amplify the
    greenhouse effect.
  • However this is gross simplification of a much
    more complex system. The concentration of water
    vapor in the atmosphere is not controlled by
    surface evaporation, but by precipitation
    systems, as described previously. Even though
    surface evaporation tries to fill the atmosphere
    with water vapor, precipitation systems do not
    allow that to happen and disperse the water vapor
    and its heating/cooling effects. Relative
    humidity's near the surface average no more than
    70 percent.
  • It is possible all that will occur if you add
    more carbon dioxide is an increase in the
    efficiency of the worlds precipitation systems
    ability to circulate and remove water vapor from
    the atmosphere, and thus no increase in global
    temperatures.
  • Therefore the assumption that an increase in
    carbon dioxide will result in an increase in
    water vapor is speculation that has no real
    scientific basis.

52
Comparison of Climate Model Assumptions with
Actual Physical Measurements
  • A number of instruments have been introduced in
    the last 25 years (such as satellites and
    balloons) which have measured some of the
    atmospheric parameters that climate models
    predict with increase in carbon dioxide.
  • One such parameter is the temperature of the
    lower and upper troposphere. Climate models
    projecting increases in global temperatures
    because of anthropogenic increases in carbon
    dioxide all project significant increases in the
    temperatures of the troposphere from the 7 to 13
    kilometer range.
  • Actual measurements of global temperatures in the
    lower troposphere do not match the predicted
    ranges.
  • The models predictions of lower troposphere
    temperatures are therefore are to be considered
    either suspect or invalid.

  • Temperature trends for the satellite era
    (C/decade). Relax it is simple. HadCRUT, GHCN
    and GISS are various compilations of surface
    temperature observations. IGRA, RATPAC, HadAT2,
    and RAOBCORE are all balloon-based observations
    of the surface and lower troposphere. UAH, RSS,
    UMD are satellite-based data for various levels
    of the atmosphere. The 22-model average comes
    from an ensemble of 22 model simulations from the
    most widely used models from throughout the
    world. The light red lines are the 2 and -2
    standard errors of the mean from the 22 models
    (from Douglass et al., 2007).

Comparison of Aqua Satellite Measurements with
Climate Models Predictions
  • Feedback measurements are at the crux of the
    global warming debate. Some of the major
    feedback mechanisms that climate models predict
    is increase in water vapor with increase in
    carbon dioxide.
  • Potential feedback mechanisms are being directly
    measured by the NASA Aqua satellite, which was
    designed and launched by NASA to measure climate
    parameters such as water vapor variations. Aqua
    satellite has been collecting data since 2002.
  • The latest data from Aqua determined water vapor
    does not increase in concentration with increases
    in carbon dioxide. (Spencer, R.F. et. al.,
    2007).

Comparison of NASA Aqua Satellite Measurements
with Climate Models Predictions
  • As stated on March 17, 2008 by Jennifer Marohasy,
    a biologist and senior fellow of Melbourne-based
    think tank the Institute of Public Affairs on ABC
    Radio National What all the climate models
    suggest is that, when you've got warming from
    additional carbon dioxide, this will result in
    increased water vapour, so you're going to get a
    positive feedback. That's what the models have
    been indicating. What this great data from the
    NASA Aqua satellite ... (is) actually showing is
    just the opposite, that with a little bit of
    warming, weather processes are compensating, so
    they're actually limiting the greenhouse effect
    and you're getting a negative rather than a
    positive feedback."
  • As explained in testimony before Congress on
    March 13, 2007 Dr. Spencer stated, As rain
    system activity and tropospheric warmth reach
    peak levels during tropical intraseasonal
    oscillations (ISOs), we measured an increase in
    outgoing infrared radiationwhich was traced to a
    decrease in cirrus cloudiness.
  • Increase in outgoing infrared radiation means the
    radiative balance of the planet will cool, not
    warm as purported by climate models predicting
    human induced anthropogenic global warming.

Argus Project and Ocean Temperatures
  • The Argus Project is a series of 3000 or more
    buoys that have been launched throughout the
    oceans to measure temperatures. They have the
    ability to dive several thousand feet in depth to
    check temperatures in the deep ocean as well as
    the surface.
  • Researchers found that the average temperature of
    the upper ocean rose by 0.16 degrees Fahrenheit
    from 1993 to 2003, and then fell 0.055 degrees
    Fahrenheit from 2003 to 2005. The recent decrease
    is a dip equal to about one-fifth of the heat
    gained by the ocean between 1955 and 2003. They
    analyzed data from a broad array of ocean
    moorings, floats and shipboard sensors, and
    supported their results with data from NASA's
    Jason and Topex/Poseidon satellites.

59
Argus Project and Ocean Temperatures
  • Monitoring the heat content of the oceans is
    vital to understanding how Earth's energy balance
    is changing. "The capacity of Earth's oceans to
    store the sun's energy is more than 1,000 times
    that of Earth's atmosphere," Lyman said. "It's
    important to measure upper ocean temperature,
    since 84 percent of the heat absorbed by Earth
    since the mid-1950s has gone toward warming the
    ocean. Measuring ocean temperature is really
    measuring the progress of global warming." The
    NOAA Pacific Marine Environmental Laboratory is
    currently developing an ocean observing system to
    better quantify changes in the ocean to include
    heat content.
  • The recent changes in ocean temperature run deep.
    A small amount of cooling was detected at the
    ocean's surface, consistent with global
    measurements of sea-surface temperature. The
    maximum amount of cooling was seen at a depth of
    about 1,300 feet, but substantial cooling was
    still observed at 2,500 feet and the cooling
    appears to extend deeper.
  • Lyman said the cause of the recent cooling is not
    yet clear. Research suggests it may be due to a
    net loss of heat from the Earth. "Further work
    will be necessary to solve this cooling mystery,"
    he said.

60
Ocean Temperatures
  • The Argus data is consistent with the finding
    that the dodecal Pacific Oscillation in the ocean
    has changed bringing cold waters to the surface
    in the northern and middle Pacific.
  • However it directly contradicts the predictions
    of most climate models that purport anthropogenic
    global warming in that those models predict ocean
    temperatures will rise.

61
ENSO Variations
  • El NiƱo/Southern Oscillation (ENSO) in the
    Pacific is the most important coupled
    ocean-atmosphere phenomenon to cause global
    climate variability on interannual time scales.
  • The following graph show its variation from
    average since the 1940s.
  • It shows a trend of lower than average
    temperatures from the 1940s to the mid 1970s,
    followed by a higher than average trend from the
    mid 1970s to 2005.
  • This correlates with the general trend of global
    temperatures, indicating ENSO is an important
    natural phenomena affecting global temperatures.

Summation
  • The hypothesis of anthropogenic global warming Is
    based on assuming the increase of carbon dioxide
    in the atmosphere this past century is due to use
    of carbon based fuels by humans.
  • The hypothesis postulates that increases in
    carbon dioxide in the atmosphere is modifying the
    radiative balance of the atmosphere so that more
    infrared radiation is trapped and increasing
    global temperatures. Climatic models are used to
    explain the mechanism of this phenomena.
  • However this hypothesis has not matched observed
    atmospheric data in the following ways

68
Invalidations Temperature
  • Proxy data and ice core data has shown carbon
    dioxide has varied by large concentrations over
    geologic time and has been much higher than the
    current 350 ppmv.
  • The suppositions of the range of normal
    atmospheric range of carbon dioxide in the
    atmosphere since the Holocene is probably flawed
    due to the limitations of Ice cores to retain
    carbon dioxide and thus the concentrations are
    undervalued. Actual measurements by highly
    accurate chemical methods of carbon dioxide this
    past two centuries do not match ice core values.
  • The geologic record indicates that increases in
    carbon dioxide have followed temperature
    increases in the atmosphere and not caused them.
  • Global temperatures increased from the 1900s to
    the 1940s, then decreased from the 1940s to the
    1970s, which does not correlate with the supposed
    human used carbon based fuel carbon dioxide
    driver phenomena.
  • In the last ten years global temperatures have
    been flat, which also does not correlate with
    observed increase in carbon dioxide.

69
Invalidations Models
  • Solar irradiance has not been a constant this
    past century and has in fact been the highest
    observed in the last 8,000 to 11,400 years,
    directly contradicting important assumptions of
    the computer models.
  • Temperature measurements in the troposphere have
    not matched model predictions, which calculate
    that the temperature must increase from 7 to 13
    kilometers above the surface in order for the
    anthopogenic mechanism to work. Actual
    measurements of temperatures in the last 25 years
    have shown temperatures in this atmospheric range
    much lower than the models predicted.
  • Recent data by Aqua satellites have found that
    the predicted carbon dioxide/water vapor feedback
    mechanism to be negative (decrease in water vapor
    and increase in infrared radiation emission into
    space with increase in carbon dioxide) instead
    of positive, as required by computer models.
    Due to limitations of the effect of carbon
    dioxide infrared absorption with concentration, a
    positive feedback mechanism is essential for the
    anthropogenic climate change hypothesis to be
    correct.
  • Argus buoys have found ocean temperatures have
    decreased in the past five years, contradicting
    most model predictions.

70
Natural Phenomena Climate Drivers
  • Variation in solar irradiance correlates very
    closely with global temperatures in both geologic
    and recent time scales.
  • In recent time scales ocean current phenomena
    such as ENSO and PDO have also correlated very
    closely with global temperatures.
  • Precipitation systems in the atmosphere have been
    shown to have large buffering effects on
    temperature increases and variations in
    atmospheric gas concentrations based on current
    NASA satellite data.

71
Conclusions
  • Actual data measuring parameters testing
    hypothesis of anthropogenic global warming have
    determined its predictions do not match actual
    atmospheric conditions.
  • Warming of the past 400 years since the Little
    Ice Age is much better explained by natural
    phenomena, the combination of increased solar
    activity and ocean current variations and their
    measurable effect on global temperatures.
  • Recent quiescence of sun during switch from solar
    cycle 23 to 24 indicate a period of global
    cooling may be starting, reinforced by the PDO
    and ENSO cooling ocean pattern cycles which have
    been observed this past two years.

The Role of the Political Organizations, the
Media, and the Scientific Community in distorting
the actual state of science on Climate Change
  • The general public is under the mistaken
    assumption that the United Nations IPCC is a
    neutral scientific body. It is not. It is a
    political organization whose charter specifically
    called for determination of how human produced
    global warming was affecting the planet. It
    assumes that humans are affecting the climate and
    looks for scientific research which may supply
    evidence for that hypothesis and ignores or
    suppresses contradictory evidence. Its general
    summations are notorious for this. It has also
    used scientific papers without proper independent
    peer review that support its position. The Mann
    papers on proxy determined historical
    temperatures being the most notorious example.
    These papers used utterly flawed statistical
    methods to analyze proxy measurements of
    historical global temperatures and state the
    earth in the late 20th centrury was the warmest
    in over 1,000 years. Outside independent review
    forced the retraction of that paper. It is now
    accepted that temperatures within the last 20
    years (called the late 20th century warm period)
    are lower than temperatures that occurred other
    cyclically occurring historical warm periods such
    as the Minoan Warm period (1400 1300 BC), the
    Roman Warm period (300 100 BC), and the
    Medieval warm period (800 1000 AD).
  • Besides the UN, organizations such as the Nobel
    committee have glorified politicians pretending
    to be scientists whose dissertations on global
    warming have been shown to be at least misleading
    and in most cases demonstratably false.

73
The Role of the Political Organizations, the
Media, and the Scientific Community in distorting
the actual state of science on Climate Change
  • The media have offered extremely poor reporting
    of the state of the science of global warming.
    The media is biased toward sensationalism,
    because it is believed this engenders good
    ratings. Therefore they consistently report the
    state of climate science with the theme the sky
    is falling and the planet is being destroyed. A
    few examples, after the year of Hurricane Katrina
    and Rita most media posited that human induced
    global warming was probably making hurricanes
    more frequent and dangerous. Did they retract
    that position after three very quiet hurricane
    years? Of course not. Has the media reported
    that there has been no increase in global
    temperatures the last ten years? No. Has the
    media reported that the Antarctica has gotten
    increasing colder overall the last 50 years and
    the amount of ice and snow mass has steadily
    increased during these 50 years? No, they report
    large ice sheet fractures and releases, which are
    spectacular, but are small compared to the amount
    of ice and snow mass increase. The media reported
    at the beginning of this summer that the north
    pole might have no ice this year. They have
    ignored the fact that this winter was the coldest
    globally in 50 years, that Alaska has had a very
    cool summer, and that there is almost no chance
    the north pole ice will vanish this year. They
    also try to frighten the public about extinction
    of polar bears due to lose of habitat, ignoring
    the fact that the polar bear population has been
    growing steadily for 50 years and now is
    extremely robust.
  • In general the media report readily news that
    predicts that humans are causing global
    temperatures to rise while ignoring scientific
    research showing these positions have no basis in
    fact. The media also attempts to demonize
    scientists whose work refutes anthropogenic
    global warming calling them climate doubters and
    darkly implying they are tools of oil companies.

74
The Role of the Political Organizations, the
Media, and the Scientific Community in distorting
the actual state of science on Climate Change
  • The scientific community is also not unbiased in
    climate research. It is much easier to obtain
    grant money if you proclaim that your research
    will investigate some aspect of humans
    destroying the planet than if you propose to
    study the natural variation of climate.
  • A large number of climate scientists careers are
    based on findings which they believed indicated
    human induced global warming. These scientist
    are reluctant to have their lifes work shown to
    be fatally flawed, just like any normal human is
    reluctant to be told his job is worthless.
    Therefore there is considerable resistance to any
    finding or funding of research that intends to
    seriously challenge that hypothesis of human
    induced global warming. Nevertheless, this
    research is proceeding and yielding results that
    directly contradict the anthropogenic hypothesis.
