Hi all, Mike, re climate change, give me a break, we have all heard the reality deniers point of view but the bottom line is 99%+ of the worlds climate scientists all agree that climate change is occurring.
The evidence provided by the unprecedented opening of a North West passage due to ice melting on a large scale in the arctic is undeniable, along with many increase in the melting of ice. That silly "Great global warming swindle" documentary that most deniers rely on has been so completely and thoroughly discredited that it's a running joke. I have a web site for the flat earth society, where they make lots of ill informed and distracting claims too but that doesn't make them right you know. For every 1 scientist who denies there are 100 who believe-do the maths, and face reality. Try driving around the SA country at the moment if you need more evidence. Even our despicable federal government which is almost unparalleled at reality denial and outright lying (and/or incompetence) in this area and most other areas, believes now. Of course you and the fringe loonies could be right and the *real* experts all wrong.........

Is there anything it it isn't responsible for? Better figure out if there is any first. See www.climateaudit.org (breakers of the infamous "hockey stick") Fairly technical. There are links there to other sites. Yes the climate changes. Lesson one at meteorology school was that 30 year averages were taken at weather stations to define the climate because it was well known that it changed on time scales longer than that so any longer averages weren't meaningful. Nobody was blaming CO2. A few facts: Of the CO2 going in to atmosphere each year the human race is responsible for under 4%. There's currently around 380 ppmv of CO2. It is increasing around 0.5 to 1% of that per year.(It varies from year to year and seasonally - hint - fossil fuel burning doesn't). Obviously there are lots of CO2 sinks. The temperature effect of increased CO2 is small - and as the effect on temperature is logarithmic most of the temperature effect has already occurred. The catatrophic warming predictions depend on increased temperature causing increased water vapour which further increases the temperature as H2O is also a greenhouse gas(not as good as CO2 but there's usually lots more of it - 0 to 4% of the atmosphere). Positive feedback. Any engineer will tell you that systems with positive feedback are unstable and tend not to stay in one state for long, usually crashing between extremes. I'll leave it as an exercise for you to find the evidence for this positive feedback. I mean *evidence* not computer models. If you can there's US$100,000 on offer at www.junkscience.com Is there human caused climate change? Almost certainly. Land use changes are a very likely contributor. Changes albedo and lost of other things when you remove vegetation and replace with bitumin, concrete and buildings or clear trees for farmland. I got stuck with explaining this to a bunch of environmental science students in a lecture in 1977. The human race doesn't know nearly enough about planetary systems but we have to be careful to use real science not political hysteria promoted by scammers (Al Gore's in town BTW) Mike Borgelt Instruments - manufacturers of quality soaring instruments phone Int'l + 61 746 355784 fax Int'l + 61 746 358796 cellphone Int'l + 61 428 355784 Int'l + 61 429 355784 email: [EMAIL PROTECTED] website: www.borgeltinstruments.com _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
