Dr Lee Gerhard: “IPCC Claims are False”

[Article originally published on electroverse.net on Sept 30, 2020]

Dr Lee Gerhard: “I never fully accepted or denied the anthropogenic global warming concept until the furore started after NASA’s James Hansen’s wild claims in the late 1980s. I went to the [scientific] literature to study the basis of the claim, starting with first principles. My studies then led me to believe that the claims were false.”

Dr Gerhard is a retired geologist from the University of Kansas. He obtained a B.S. in Geology in 1958, an M.S. in Paleontology minor. in 1961, and a Ph.D. in Geology in 1964. Gerhard believes that climate change has been a natural phenomenon driven by natural processes for 4.5 billion years. But that cultural pressures now exist to identify a human cause for current trends.

As Peter Flawn, President Emeritus of the University of Texas, writes, “All geologists early in their careers are introduced to solving problems through multiple working hypotheses — of deriving solutions from the data rather than, as is common among some social scientists, settling upon a solution consistent with the reigning theory and supporting it with data selectively chosen.” Gerhard adds “that although many geologists have expressed concern about the paucity of data supporting supposed human-driven climate change, scientific tests to falsify the hypothesis have been lacking.”

In 2001, Dr Gerhard was listed as an expert reviewer of the previous two IPCC reports. He considers his stance on Earth’s climate objective and based on science, aspects he feels IPCC reports routinely lack.

“Some argue that the Arctic is melting, with the warmest-ever temperatures. One should ask, ‘How long is ever?’ The answer is since 1979. And then ask, ‘Is it still warming?’ The answer is unequivocally ‘No.’ Earth temperatures are cooling,” says Gerhard.

Gerhard goes on to state that the global temperature changes naturally all of the time, in both directions and at many scales of intensity. He points out that the warmest year in the U.S. in the last century was 1934, with the cooling observed after 1998 “absolutely falsifying claims that human carbon dioxide emissions are a controlling factor in Earth temperature.”

“During the last 100 years temperature has both risen and fallen, including the present cooling. All the changes in temperature of the last 100 years are in normal historic ranges, both in absolute value and, most importantly, rate of change.

“Voluminous historic records demonstrate the Medieval Climate Optimum (MCO) was real and that the ‘hockey stick’ graphic [crafted by Michael Mann–shown below] that attempted to deny that fact was at best bad science. The MCO was considerably warmer than the end of the 20th century,” says Gerhard.

Mann’s ‘hockey stick’ was the basis for the IPCC’s conclusion that “there is discernible human impact on climate.” However, and in a first step toward restoring the rigor of science in the global climate debate, a committee of the National Academy of Sciences back in 2006 presented the results of its directed study of the science behind the infamous graph.

The Academy’s report identified the failure of the hockey stick to model climate beyond the past 400 years, as evidenced by its inability to reflect the medieval climate optimum. The optimum has been extensively and accurately recorded–via historical documentation and proxy data–yet it cannot be explained by computer models based on equations that assume that greenhouse gases dominate climate change — models that predict massive increases in Earth’s atmospheric temperature because of the additions of a small percentage of human-derived carbon dioxide.

Michael Mann’s Hockey Stick graph (for more on the deception, click here).


The IPCC needed to remove the MCO from the historical record books because the period blew apart their global warming theory — any forcing other than CO2 able to cause terrestrial warming is an inconvenient spanner in the works, and so, with the help of Mann, the panel completely erased every one of them from history in one clean swipe.

This was a brazen plan, particularly given the extensive data, records and proxies out there demonstrating that the MCO did indeed occur; the same natural phenomena that prove the existence of the preceding Roman-era warm event, too; and the very same data, records and proxies that were on show again recently during our modern warming event–the modern Grand Solar Maximum.

Climate, it turns out, is driven mainly by the Sun and the impact solar activity has on the oceans.

Ironically, it is the IPCC that are the true climate deniers.

Dr. Tim Ball’s temperature graph for the past 1,000 years is generally considered much closer to the actual reality.


The COLD TIMES are returning, the mid-latitudes are REFREEZING in line with historically low solar activitycloud-nucleating Cosmic Rays, and a meridional jet stream flow (among many other forcings, including the impending release of the Beaufort Gyre).

    But what causes the decline in O2?
    https://scrippso2.ucsd.edu/
    If other then influence UV on fythoplankton which causes also decline in ability to absorb CO2.

    1. TheMronz

      Ocean temperatures.
      The cooler the water the more CO2 it can absorb
      Hence there is more CO2 in the atmosphere when the oceans are warm.
      So temperatures and CO2 concentrations do correlate.
      But most importantly CO2 levels FOLLOW temperature not vice versa. In fact, CO2 continues to rise for a period even after temperatures fall. This the data readily supports.

      1. Roscomac

        The other thing people miss is the atmosphere has no upper limit as to how much CO2 it can contain BUT the oceans have well known limits.

        We know this from paleo-climate data where 10 times the current atmosphere limits were noted but the oceans could not have been any more “acidic” than at present as this was the times of the explosion of life both on land and the oceans including all the forms of life reliant on calcium carbonate exoskeletons including corals which are supposedly on a path to extinction if you listen to the idiotic alarmists.

        IF you have a real established hypothesis, real evidence to support it then you don’t need alarmism – kinda says it all really !

  2. Hadaqar

    Just looking at the graph my first expectation is that the sun is ready to do another 500yr warming cycle?

  3. MattH

    The most probable cause of a decline of atmospheric O2 is the timing of perihelion near the Southern summer solstice.
    If geomagnetic activity and sun activity and cycles are stable this timing of the summer solstice leads to an increase in temperature of the oceans.

    Approx. 60% of atmospheric oxygen is produced in the ocean. A warming ocean inhibits oxygen production by algae such as coccolithophores.

    I am curious to read comment on any other contributing factor.

  4. Richard Greene

    IPPCC predictions have little or no similarity to any past climate change. They are just meaningless predictions of CAGW that have been wrong since 1988

  5. rod

    There is abundnat physical geological evidence that sea levels were 5 or more metres higher during the Medieval CO. One: marine terraces now stranded above current levels along the south coast of Britain and elsewhere; and Two: relict ports from that period now kilometres inland (and some Roman ones from the Roman Warm Perios too).

  6. Roscomac

    Mann’s graph is obviously totally unscientific and I cannot for the life of me understand why any real scientist would not expound that simple fact !

    Mann’s graph is a composite of dubious quality tree ring data up to the mid sixties but after that date it uses equally dubious temperature data.

    This is not scientific !

    To any realist this is clearly scientific fraud – I don’t get how anyone can defend it !

    It doesn’t matter what result has been obtained it is a composite fraud and the refusal of mainstream climate “science” to denounce it is simply staggering !

    It always fascinates me that back in 1850ish when these charts begin for CO2 for the purposes of hoodwinking the public, the level then was actually dangerously low. I believe the figure of 145ppm is the point where the LACK of CO2 would cause our extinction.

    No one bothers to mention that in a cinema/theatre levels can be 7000ppm and yet surprise surprise no one seems to die in these establishments yet were supposed to be on the brink of extinction if the levels rise to 400ppm. Currently around 415ppm I believe yet we still seem to be here.

    Commercial greenhouses take CO2 levels to 1200ppm as it makes the plants grow better so why would we not want that? Do the employees die if they enter?

    And as for 2 deg C rise killing us all how can it be 50+ deg in places like Bahrain and 18 deg in Ireland where I am yet if the temperature here gets to 25 deg C (about the max here) we don’t all keel over an die. How very inconvenient of us. I am sure they don’t all die if it gets to 54 in Bahrain.

    The aroma of bovine excrement is extremely strong.
