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?:  What is Climate Change? Throughout time the Earth’s 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 it’s slowing down. The world’s 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. Pennekamp Park – Key Largo SCOOP - “Reefs keep pace with 125 metre sea level rise”:  Pennekamp Park – Key Largo SCOOP - “Reefs keep pace with 125 metre sea level rise” Sea Level Rise Is Slowing Down:  Sea Level Rise Is Slowing Down Athabasca Glacier has been receding since the Little Ice Age:  Athabasca Glacier has been receding since the Little Ice Age Moraine From the Little Ice Age :  Moraine From the Little Ice Age Sea level Rising – not as fast as the Land! :  Sea level Rising – not as fast as the Land! Earth’s crust floats on the mantle like ice in water 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 Relax, the planet is fine… The Wegman Report: Ad Hoc Committee on the Hockey Stick Global Climate Reconstruction, This report was authored by Edward J.

Wegman, George Mason University, David W. Scott, Rice University, and Yasmin H. Said, The Johns Hopkins University Solar System Perspective:  Solar System Perspective What If?:  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:  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 +15°C rather than -18°C if we had no water vapour or CO2 Important Facts:  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 remainder Contribution to the ‘Greenhouse Effect’ (including water vapour) http://www.geocraft.com/WVFossils/greenhouse_data.html:  Contribution to the ‘Greenhouse Effect’ (including water vapour) http://www.geocraft.com/WVFossils/greenhouse_data.html Is Global Warming Happening?:  Is Global Warming Happening? Lets examine some very wiggly curves Death Valley California (not much urban growth here) - Berkeley California:  Berkeley California No global warming here :  No global warming here Blaine Washington :  Blaine Washington New York NY:  New York NY Albany NY:  Albany NY Michael Crichton - “State of Fear”, December 2004, Harper Collins:  Michael Crichton - “State of Fear”, December 2004, Harper Collins New York city has a fever then why not Albany? Harrisburg Pa – Civil War gap :  Harrisburg Pa – Civil War gap Chicago Illinois:  Chicago Illinois Buffalo NY:  Buffalo NY Key West Florida:  Key West Florida Global Warming:  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 Realistically:  Realistically The planet is not warming in the dramatic manner the alarmists claim There are many other sites that demonstrate cooling I accept slow climate change but not the drama EARTH’S CLIMATE IS ALWAYS CHANGING I do not accept the popular ‘cause’ – CO2 Why are the graphs so wiggly? Because climate is not weather Niagara Falls NY – 1911 The next Ice Age predicted…:  Niagara Falls NY – 1911 The next Ice Age predicted… Relax, the planet is fine… The Wegman Report: Ad Hoc Committee on the Hockey Stick Global Climate Reconstruction, This report was authored by Edward J.

USA 103, 10536-10543 Fig. 6. Climate reconstructions over the last two centuries [SIC : millennia]. Medieval warm period missing – Little Ice Age ???:  Thompson, Lonnie G. et al. (2006) Proc. Natl. Acad. Sci. USA 103, 10536-10543 Fig. 6. Climate reconstructions over the last two centuries [SIC : millennia]. Medieval warm period missing – Little Ice Age ??? Kamél, 2003:  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 around. The extra CO2 could at most add a little extra warming to what is going on, but not even that is certain”. CO2 increase in the atmosphere is a trailing phenomenon:  CO2 increase in the atmosphere is a trailing phenomenon 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:  CO2 has inverse solubility in liquid Solubility of solids increases directly with temperature of the solvent sugar dissolves more rapidly in hot water than cold Carbon dioxide dissolves quickly in cold water and evolves rapidly out of warm water Don’t shake your Doctor Pepper! Observations :  Observations 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 And…:  And… 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:  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 change. Climate Change 2001: The Scientific Basis Section 1.1.2 The Climate System Absorption wavelength CO2 vs. H2O:  Absorption wavelength CO2 vs. H2O Three CO2 absorption wavelengths at 1.4, 1.9 and 2.4 μm cannot compete with nine H2O bands Beck, Ernst-Georg, 2007: 180 Years of Atmospheric CO2 Measurements by Chemical Means, Energy and Environment, Vol. 8 No.2 March.:  Beck, Ernst-Georg, 2007: 180 Years of Atmospheric CO2 Measurements by Chemical Means, Energy and Environment, Vol. 8 No.2 March. Beck, Ernst-Georg, 2007: 180 Years of Atmospheric CO2 Measurements by Chemical Means, Energy and Environment, Vol. 8 No.2 March.:  Beck, Ernst-Georg, 2007: 180 Years of Atmospheric CO2 Measurements by Chemical Means, Energy and Environment, Vol. 8 No.2 March. UN IPCC 1740 – 2000:  UN IPCC 1740 – 2000 Slide40:  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 CO2?” CO2 data used by the UN IPCC has fatal flaws IPCC CO2 data is F(Flawed)UBAR:  IPCC CO2 data is F(Flawed)UBAR Downward forcing - all greenhouse gasses - vs. increasing CO2 content - Willis Eschenbach:  Downward forcing - all greenhouse gasses - vs. increasing CO2 content - Willis Eschenbach CO2 Feedback effect:  CO2 Feedback effect Has a geometrically wasting property (Kamél, 2003) 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 ?:  Well then what is the likely cause ?

The subtle part…:  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… It’s all of those plus … Danish National Space Centre:  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 Earth’s 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 Earth’s atmosphere has been experimentally identified for the first time.” http://www.spacecenter.dk/publications/press-releases/getting-closer-to-the-cosmic-connection-to-climate Danish Space Centre Theory:  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 warms Potentially large sources of cosmic radiation - our star is one pixel Betelgeuse is 427 light years away; Antares 600 light years away.:  Potentially large sources of cosmic radiation - our star is one pixel Betelgeuse is 427 light years away; Antares 600 light years away.

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:  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? www.CO2Science.org My hypothesis is volcanic:  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:  Skepticism or Objectivity Moving to higher ground..
