Title: Global Warming and Science

Global Warming and Science
  • So far the balanced story of basic science is not
    getting through to the public
  • There is at least one alternate hypothesis
  • and a new theory
  • Fran Manns, Artesian Geological Research, Toronto

What is Climate Change?
  • Throughout time the Earths climate has varied
  • Since the base of the Pleistocene (1.8 M ya)
    there have been at least 30 glacial -
    interglacial cycles of 40,000 years to 100,000
    years duration with interglacial periods warmer
    than now between them
  • Sea level has risen 125 metres in the past 20,000
    years. That 6 mm a year (arithmetic average).
  • IPCC recently cited 2-3 mm a year one might
    say its slowing down.
  • The worlds coastal tribes have flood myths
    because they migrated around the world and lived
    upon the continental shelves
  • Between glacial ages the climate varies due to
    external and internal influences some result in
    cooling. Others allow the Earth to warm
  • There are short-term cycles e.g. El Niño,
    among others for example - the 10 to 12 year
    long solar energy cycles, and cycles that relate
    to oscillation of Atlantic and Pacific ocean
    masses, and the Milankovich orbital cycle.

Sea level Rising not as fast as the Land!
  • Earths crust floats on the mantle like ice in
  • Pushed down by ice it is now rising
  • Vivid examples of residual rebound are
    Scandinavia and central Canada
  • The northern Baltic countries are rising nearly 1
    metre per 100 years
  • The Hudson Bay region still needs to rebound as
    much as 150 m. in order for isostatic equilibrium
    to be achieved

Solar System Perspective
What If?
  • If The atmosphere did not absorb incoming heat,
    we would roast all day and freeze-dry at night
    and end up like sun-dried tomatoes
  • Mercury - 427 to 172 ºC
  • Mars - temperate zone soil
  • 27 to 80 ºC
  • Moon - 107 to - 153 ºC

What is the Greenhouse Effect?It is an analogy
to a garden greenhouse
  • Certain gasses in the atmosphere are alleged to
    absorb heat energy and reduce the amount that
    escapes into space
  • This trapping of heat from our only source of
    warmth the Sun by the atmosphere is known as
    the Greenhouse Effect
  • The greenhouse effect is a hypothesis
  • This hypothesis (or the equally valid cloud cover
    hypothesis) gives us a global average temperature
    of 15C rather than -18C if we had no water
    vapour or CO2

Important Facts
  • Water vapour is the most important agent - 60
    - 98 of the heat trapping is due to water
    vapour in the atmosphere (jury still out)
  • CO2 and other minor gasses account for the

Contribution to the Greenhouse Effect

Is Global Warming Happening?
  • Lets examine some very wiggly curves
  • Death Valley California (not much urban growth
    here) -

Berkeley California
No global warming here
Blaine Washington
New York NY
Albany NY

  • New York city has a fever then why not Albany?

Harrisburg Pa Civil War gap
Chicago Illinois
Buffalo NY
Key West Florida
Global Warming
  • Typically the majority of weather stations yield
    corrupt time series data
  • Those weather stations are located where people
    are living. Thus, it is far from a random sample
    of the surface of the world, rather a measure of
    increasing human density
  • Death Valley, Key West, and Blaine are far
    (remote) from urban centres and are likely more
    reliable Who knows about Berkeley? Albany vs.
    New York City?
  • Since 1979, temperatures have been measured from
    satellites. Not surprisingly, these measurements
    give a much smaller warming.
  • Most of the graphs show little or no warming
    since 1950

  • The planet is not warming in the dramatic manner
    the alarmists claim
  • There are many other sites that demonstrate
  • I accept slow climate change but not the drama
  • I do not accept the popular cause CO2
  • Why are the graphs so wiggly?
  • Because climate is not weather

Little Ice Age ???
Kamél, 2003
  • In the past couple of years, new and better
    analysis of the Antarctic ice data, giving a
    better time resolution, have shown that first
    temperature rises, and then carbon dioxide levels
    increase. It is the temperature increase which
    causes the increase in CO2 and not the other way
  • The extra CO2 could at most add a little extra
    warming to what is going on, but not even that is

CO2 increase in the atmosphere is a trailing
  • Throughout the greatest temperature transitions
    experienced by the planet over the past 420,000
    years, atmospheric CO2 concentration has been
    proven to have been a follower, and not a leader,
    of climate change, rising from one to five
    thousand years after major increases in air
    temperature, and falling in similar manner
    throughout the course of the past four
    glacial/interglacial cycles (Mudelsee, M., 2001).

CO2 has inverse solubility in liquid
  • Solubility of solids increases directly with
    temperature of the solvent
  • sugar dissolves more rapidly in hot water than
  • Carbon dioxide dissolves quickly in cold water
    and evolves rapidly out of warm water
  • Dont shake your Doctor Pepper!

  • Warming precedes CO2 increase - likely due to
    warming of the oceans
  • CO2 has inverse solubility in liquid (warm your
    Guinness to see this effect)
  • CO2 has a geometrically wasting greenhouse gas
    effect more CO2 less effectiveness

  • You might say, and alarmists say every day,
    that the new anthropogenic CO2 from the
    industrial revolution is tipping the climate over
    into uncontrollable heating

Water vapour is the most important greenhouse gas
  • The most variable component of the atmosphere is
    water in its various phases such as vapour, cloud
    droplets, and ice crystals. Water vapour is the
    strongest greenhouse gas. For these reasons and
    because the transition between the various phases
    absorb and release so much energy, water vapour
    is central to the climate and its variability and

UN IPCC 1740 2000
CO2 data used by the UN IPCC has fatal flaws
  • Beck shows several instances when CO2 was higher
    than today at Mauna Loa
  • Most recently (1942) CO2 exceeded 400 ppm
  • Cynics would say the Beck (2007)data are
    regionalized variables and realists might say
    Why use Mauna Loa, an active volcano that emits

IPCC CO2 data is F(Flawed)UBAR
Downward forcing - all greenhouse gasses - vs.
increasing CO2 content - Willis Eschenbach
CO2 Feedback effect
  • Has a geometrically wasting property (Kamél,
  • Analogous to Venetian blinds and light
  • Adding a second and third set of Venetian blinds
    to the same window becomes decreasingly effective
    in blocking outgoing light
  • More CO2 less additional greenhouse effect
  • Increase in CO2 has less effect because
  • Carbon dioxide in the Earth's atmosphere has
    exactly one important spectral line in the
    infrared part of the spectrum. This line is
    clearly saturated.
  • If you increase the number of CO2 molecules in
    the atmosphere, not much will happen

Well then what is the likely cause ?
Look up! - recognise the variation is in the
fourth significant digit
CO2 vs. Friis-Christensen and Lassen (Science,
1991) "Dr. Tim Patterson after Friis-Christensen
Lassen, 1991"
CO2 and Temperature Anomaly
  • Temperature rise preceded CO2 from 1890 to 1950
  • CO2 does not correlate with temperature anomaly
    from 1940 to 1970
  • Temperature rise does correlate with solar
  • CO2 rise cannot be a cause of warming

Friis-Christensen and Lassen (1991) Science
  • 95 correlation between sunspot peak frequency
    and the temperature anomaly
  • Sunspot curve, moreover, leads the temperature
  • But, correlation is not causation
  • What is the cause?

The subtle part
  • It is not only the number of sunspots
  • It is not only the heat flux
  • It is not only the peak frequency
  • Its all of those plus

Danish National Space Centre
  • It is already well-established that when cosmic
    rays, which are high-speed atomic particles
    originating in exploded stars far away in the
    Milky Way, penetrate the Earths atmosphere, they
    produce substantial amounts of ions and release
    free electrons.
  • results from the Danish experiment show that the
    released electrons play a significant role in
    promoting the formation of building blocks for
    cloud condensation nuclei, on which water vapor
    condenses to make clouds. Hence, a causal
    mechanism by which cosmic rays can facilitate the
    production of clouds in Earths atmosphere has
    been experimentally identified for the first
  • http//

Danish Space Centre Theory
  • Active sun ? enhanced magnetic and thermal flux
    solar wind ? geomagnetic shield response ? less
    low-level clouds ? less albedo (less heat
    reflected)  ? warmer climate
  • Less active sun ? reduced magnetic and thermal
    flux reduced solar wind ? geomagnetic shield
    drops ? galactic cosmic ray flux ? more low-level
    clouds ? More snow ? more albedo (more heat
    reflected) ? colder climate
  • That's how the bulk of climate change works
  • Coupled with sunspot peak frequency there are
    cycles of global warming and cooling like waves
    in the ocean
  • When the waves are closely spaced, the planet

Potentially large sources of cosmic radiation -
our star is one pixel Betelgeuse is 427 light
years away Antares 600 light years away.
We are at the end of the 23rd Cycle since
sunspots were first recorded
Why, realistically, conspiracy theories aside
  • Is CO2 the target?
  • CO2 hypothesis has precedence (1897)?
  • Media propagation? Bottom Line
  • Repetition of stale science sells paper
  • Bandwagon science? - DDT and Malaria!
  • Consensus science? - Copernicus and Galileo!
  • Publish or perish? - Mann and the Hockey Stick
  • Research grants? Tied to outcome
  • All of the above?

Original Sin
  • Gracious no! Humans can only claim
    responsibility, if that's the word, for about
    3.4 of carbon dioxide emitted to the atmosphere
    annually, the rest of it is all natural (IPCC,
    Woods Hole)
  • Anthropogenic is 0.11 of the global CO2 cycle
  • Better term is Anthropocentric implying
    narcissism of the environmental lobby groups
  • Was that not the Galileo-Copernican dilemma?

My hypothesis is volcanic
  • Eruption of Krakatau, 1883
  • Key West time series There has not been much
    warming of the Gulf of Mexico in modern time

Skepticism or Objectivity
Moving to higher ground.. Here is An
Inconvenient Truth
  • "A scientific hypothesis that survives
    experimental testing becomes a scientific theory"

Take this test!

Ad Hominem - ICPPIntercontinental Conspiracy
Perhaps Political
  • Main players will not debate
  • The world would watch
  • They have a weak argument
  • The anthropocentric bloggers will not talk about
    scientific issues
  • Dont have science knowledge
  • Flawed data
  • GIGO
  • Generalizations from particular
  • Polar ice and bears
  • Local weather
  • Hurricanes
  • Argumentum ad Hominem too common
  • Precautionary Principle USED against all odds
