  • Going green will not be enough - Wally Broecker, 2008.

    Response to Northwest Airlines posting on climate change:
    Will voluntary measures result in short-term movement toward non-fossil lighter-than-air craft? I hope so. Regardless of climate, I think we'd enjoy flying these far better!

    I know Boeing Inc. has long dreamed of building flying wing airships of gigantic capacity compared to the aluminum tubes we fly today. Why not mark out a bold vision toward owning floating cities able to move by slightly reinforcing rippling movements of the outer carbon fabric, perhaps using tiny solar powered nanofiber 'muscles'? You could fly low enough to avoid high, or any, pressurization; imagine the views through the massive 'glass floors' possible in these craft! Geography as it unfolded below would become of avid general interest, though the daylight below would only be preserved with the assistance of many, many exterior sun-dispensing mirrors. Individuals or families could in-flight decide to parasail down within walking distance of their final destinations.

    We could get there by reusing the wonderful lightweight but fuel-inefficient airframes being mothballed to date. Airships could be flown singly at first, then tied together into a massive latticework. No fancy hydrogen or helium technology, just good old hot air could provide most of the lift in a self-adjusting envelope. It would work like a giant Segue of the skies, undulating, compensating for meteorological conditions, balancing weight and distribution changes effortlessly. Then what if a number of these latticed airships were bundled above one another until a giant square 'balloon' of tremendous mass were built up, able to lift the hull of a cruise ship or aircraft carrier or a mountain of materials? What if several such balloons were coordinated to lift the equivalent of a stadium or small city? The cost to an individual for global intercity and intercontinental transport would drop to micropayments, volume would zillionify, and the cost to the atmospheric composition would be far lower as well. We could all live everywhere across the globe and enjoy a productive world saved from the far worse future restricted to one in ten of us clustered above a barren earth along the arctic rim.

    Imagine asking, 'Do you want to catch the morning or the evening flight? Well, at any time just walk right through any of the open archways on any side of our spectacular floating city, always boarding. Enjoy flying, dining, learning and recreating on NorthSouthEastWest Aircities!'

    Think big! No small plans have the magic to stir the human soul! :)

  • Here’s some current information that I believe will enlighten the serious minded attempting to grapple with the complexities of global warming science.

    There is no doubt that the United Nations IPCC’s version of global warming is winning the public relations battle. The proof is that our governments are now implementing public policy intended to reduce the rise of the earth’s temperature.

    For those who are paying serious attention however, it is increasingly difficult to comprehend how they can justify discounting the growing chorus of dissenting views and agreeing with VP Gore that dissenters are corrupt quacks.

    Here are two current examples:

    UN Blowback: More Than 650 International Scientists Dissent Over Man-Made Global Warming Claims
    If all these guys are quacks, then Donald Duck deserves new respect.

    Then there’s this report that challenges the validity of IPCC’s climate models:

    The study’s conclusion is worthy of serious consideration:
    “Even if temperature had risen above natural variability, the recent solar Grand Maximum may have been chiefly responsible. Even if the sun were not chiefly to blame for the past half-century’s warming, the IPCC has not demonstrated that, since CO2 occupies only one-ten-thousandth part more of the atmosphere that it did in 1750, it has contributed more than a small fraction of the warming. Even if carbon dioxide were chiefly responsible for the warming that ceased in 1998 and may not resume until 2015, the distinctive, projected fingerprint of anthropogenic “greenhouse-gas” warming is entirely absent from the observed record. Even if the fingerprint were present, computer models are long proven to be inherently incapable of providing projections of the future state of the climate that are sound enough for policymaking. Even if per impossibilethe models could ever become reliable, the present paper demonstrates that it is not at all likely that the world will warm as much as the IPCC imagines. Even if the world were to warm that much, the overwhelming majority of the scientific, peer-reviewed literature does not predict that catastrophe would ensue. Even if catastrophe might ensue, even the most drastic proposals to mitigate future climate change by reducing emissions of carbon dioxide would make very little difference to the climate. Even if mitigation were likely to be effective, it would do more harm than good: already millions face starvation as the dash for biofuels takes agricultural land out of essential food production: a warning that taking precautions, “just in case”, can do untold harm unless there is a sound, scientific basis for them. Finally, even if mitigation might do more good than harm, adaptation as (and if) necessary would be far more cost-effective and less likely to be harmful.
    In short, we must get the science right, or we shall get the policy wrong. If the concluding equation in this analysis (Eqn. 30) is correct, the IPCC’s estimates of climate sensitivity must have been very much exaggerated. There may, therefore, be a good reason why, contrary to the projections of the models on which the IPCC relies, temperatures have not risen for a decade and have been falling since the phase-transition in global temperature trends that occurred in late 2001. Perhaps real-world climate sensitivity is very much below the IPCC’s estimates. Perhaps, therefore, there is no “climate crisis” at all. At present, then, in policy terms there is no case for doing anything. The correct policy approach to a non-problem is to have the courage to do nothing.”

    While the global warming alarmists have done a masterful public relations job in promoting their agenda, they are losing badly in the areas of science, logic and common sense.

Weather Climate Change

  2. <ul><ul><ul><li>How do we know that the world’s climate is changing? Records in developed countries such as ours stretch back over 150 years; but other parts of the world, the open oceans, most of the Southern Hemisphere in general and Antarctica in particular, have little information on which we can base our assumptions. </li></ul></ul></ul>
  3. Of course there are historical sources other than the official records. Weather diaries and records have been kept by amateur meteorologists, and books, paintings and engravings can also give a flavour of past climates, such as those depicting fun, fairs and frivolity on the river Thames.
  4. <ul><ul><ul><li>Even the cave paintings of France show a time of icy chill and animals of the tundra. </li></ul></ul></ul>
  5. <ul><ul><ul><li>Staying in France, the ‘Mer de Glace’ a glacier in the Alps near Chamonix has been charted for hundreds of years. It has exhibited a general retreat of around 1500 metres in the past </li></ul></ul></ul><ul><ul><ul><li>200-250 years, evidence for global warming, </li></ul></ul></ul><ul><ul><ul><li>perhaps? </li></ul></ul></ul>
  6. <ul><ul><ul><li>But going back further, before modern human beings were around, what can we base our claims for past climatic change on? </li></ul></ul></ul><ul><ul><ul><li>Some of the evidence is to be found inside the world’s ice caps. As layer upon layer of snow builds up, slowing turning to glacier ice, microscopic air bubbles can be trapped within the ice. </li></ul></ul></ul><ul><ul><ul><li>These air bubbles, when sampled in ice cores going back to conditions that existed up to 10,000 years ago, give us information about atmospheric air density and gaseous content. Even tiny volcanic dust particles have been found informing us about past volcanic eruptions. </li></ul></ul></ul>
  7. Then there’s dendrochronology, the study of annual growth rings of trees; the word itself combines two Greek words, ‘dendron’ for trees and ‘chronos’ for time.
  8. <ul><ul><ul><li>The size of the growth rings can give important information about climate since temperature, the length of the growing season and frosts are key elements controlling the growth of trees. </li></ul></ul></ul>
  9. <ul><ul><ul><li>Perhaps the best and most widely used method for reconstructing climatic conditions over the past 15,000 years is pollen analysis. Ever since the snowy wasteland of Britain was colonised by herbs, plants and trees after the last ice age, pollen has been scattered to the four winds. </li></ul></ul></ul>
  10. <ul><ul><ul><li>Microscopic pollen grains are very resistant to decay and are usually well preserved in peaty sediments. The numbers and types of plants that were present as shown by the pollen grains and the plant communities that existed are firm evidence of past climates. And, luckily, there’s lots of pollen, well, there should be since one flower can produce up to 1 million grains! </li></ul></ul></ul>
