Well would how would you vote? I for one would will miss him when he's gone. He provided excellent entertaiment. Like when he dropped the dog Here in Germany we only have boring ugly politicians like Angie. (see attached) Dave Fallschirmsport Marl -
"Smoking Gun" Report on Global Warming is coming
speedy replied to ChasingBlueSky's topic in Speakers Corner
Form Junkscience.com today.. The infamous "smoking gun," from bombshell to bomb... In Earth's Energy Imbalance: Confirmation and Implications Hansen, et al, state: Our climate model, driven mainly by increasing human-made greenhouse gases and aerosols, among other forcings, calculates that Earth is now absorbing 0.85 ± 0.15 watts per square meter more energy from the Sun than it is emitting to space. This imbalance is confirmed by precise measurements of increasing ocean heat content over the past 10 years. The associated media release is entitled "Earth’s Energy Out of Balance: The Smoking Gun for Global Warming" When that paper was written the model output was a fair wiggle-fit with Willis (2004) and Levitus (2004). So, Hansen's model is dumping heat into the oceans at roughly 0.8 Wm-2 and the bulk ocean heat rise mid-1993 - mid-2003 sort of matched that -- if only the world would remain constant and conform to the models we'd have this "global warming" thing sorted. Like all happy accidents, however, this good thing came to an end, too. Lyman et al (2006), using updated data from the same source, show that the period 2003-2005 involves a sudden ocean cooling at a rate of -1.0 ± 0.3 Wm-2 over the period, which means Hansen's model is calculating wrongly in both magnitude and sign. No one expected this loss of one-fifth of the heat stored in the ocean since 1955 and no model predicted it. Its cause is unclear but we appear to be witnessing Earth dumping heat to space via the atmosphere. Now Hansen's model has three years of data (to date) where it's incorrectly dumping heat into the oceans at a rate of >0.8 Wm-2 when it should have been removing it at -1.0 Wm-2, making net error of +1.8 Wm-2 over more than 70% of the planet -- call it excess global forcing of at least 1.25 Wm-2 for that period. Lyman et al. go so far as to state: Including the recent downturn, the average warming rate for the entire 13-year period is 0.33 ± 0.23 W/m2 (of the Earth's total surface area). Think about that for a moment -- that's just 0.1 - 0.56 Wm-2. Dave Fallschirmsport Marl -

Senator Responds to CNN Hit Piece On Global Warming
speedy replied to rushmc's topic in Speakers Corner
If they maintained their lines properly the would not be so worried about trees falling on them. The 120 flights cancelled at Frankfurt airport was less than 10% of all flights that went ahead that day. They were short on capacity because they wanted a little more separation on take off/ landing. It was quoted as the worst storm in 20 years. I don't remember anything about a storm here 20 years ago. Guess there was not so much media hype then. They maybe had more workers to keep the railway lines clear of potentially dangerous trees. They maybe did not have such congested airports. They didn't have 24 hour news channels then. Dave Fallschirmsport Marl -
Senator Responds to CNN Hit Piece On Global Warming
speedy replied to rushmc's topic in Speakers Corner
I am afraid your are easily fooled by media reporting. Of course they report gusts of up to 200 kmh. As I said, put your reporters on the right mountain. I was here, right in the middle of it, I know what I saw. You believe the hype, I'll stick with what I experienced in Dortmund, Germany. Even my crappy little wooden shed in the garden showed no signs of damage. I really wish the "hurricane" had blown down that damm tree blocking my satelite dish. Ho hum, guess I'll have to get the chain saw out after all. Dave Fallschirmsport Marl -

speedy replied to rushmc's topic in Speakers Corner
Hurricanes, Gales, call em what you will , but 70 mph gusts are not that rare in northern europe. Of course if you shove a T.V. crew on top of a mountian you might be able to show some gusts that are a tad higher. But from where I was sitting, apparently in one of the worst hit areas, it did not seem anything like what happened in New Orleans. On the contrary, it seemed like a bog standard windy day in lancashire, north west England. Dave Fallschirmsport Marl -

The last one we had was far from unexpected. The only unexpected part about the event was that the weather forecast was actually right. Interesting how the Germans called it a hurricane and the British called the winds gales. We had a lot of days with gales when I was a kid living in England. That was at the time of the global cooling scare. Dave Fallschirmsport Marl -
Tandems, Hurting or helping membership?

Definately helping. I have seen many tandems that decide to take up the sport after their first jump. These are people that would not have made their 1st jump alone. Dave Fallschirmsport Marl -

From National Post Will the sun cool us? LAWRENCE SOLOMON Financial Post Friday, January 12, 2007 The science is settled" on climate change, say most scientists in the field. They believe that man-made emissions of greenhouse gases are heating the globe to dangerous levels and that, in the coming decades, steadily increasing temperatures will melt the polar ice caps and flood the world's low-lying coastal areas. Don't tell that to Nigel Weiss, Professor Emeritus at the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, past President of the Royal Astronomical Society, and a scientist as honoured as they come. The science is anything but settled, he observes, except for one virtual certainty: The world is about to enter a cooling period. Dr. Weiss believes that man-made greenhouse gases have recently had a role in warming the earth, although the extent of that role, he says, cannot yet be known. What is known, however, is that throughout earth's history climate change has been driven by factors other than man: "Variable behaviour of the sun is an obvious explanation," says Dr. Weiss, "and there is increasing evidence that Earth's climate responds to changing patterns of solar magnetic activity." The sun's most obvious magnetic features are sunspots, formed as magnetic fields rip through the sun's surface. A magnetically active sun boosts the number of sunspots, indicating that vast amounts of energy are being released from deep within. Typically, sunspots flare up and settle down in cycles of about 11 years. In the last 50 years, we haven't been living in typical times: "If you look back into the sun's past, you find that we live in a period of abnormally high solar activity," Dr. Weiss states. These hyperactive periods do not last long, "perhaps 50 to 100 years, then you get a crash," says Dr. Weiss. 'It's a boom-bust system, and I would expect a crash soon." In addition to the 11-year cycle, sunspots almost entirely "crash," or die out, every 200 years or so as solar activity diminishes. When the crash occurs, the Earth can cool dramatically. Dr. Weiss knows because these phenomenon, known as "Grand minima," have recurred over the past 10,000 years, if not longer. "The deeper the crash, the longer it will last," Dr. Weiss explains. In the 17th century, sunspots almost completely disappeared for 70 years. That was the coldest interval of the Little Ice Age, when New York Harbour froze, allowing walkers to journey from Manhattan to Staten Island, and when Viking colonies abandoned Greenland, a once verdant land that became tundra. Also in the Little Ice Age, Finland lost one-third of its population, Iceland half. The previous cooling period lasted 150 years while a minor crash at the beginning of the 19th century was accompanied by a cooling period that lasted only 30 years. In contrast, when the sun is very active, such as the period we're now in, the Earth can warm dramatically. This was the case during the Medieval Warm Period, when the Vikings first colonized Greenland and when Britain was wine-growing country. No one knows precisely when a crash will occur but some expect it soon, because the sun's polar field is now at its weakest since measurements began in the early 1950s. Some predict the crash within five years, and many speculate about its effect on global warming. A mild crash could be beneficial, in giving us Earthlings the decades needed to reverse our greenhouse gas producing ways. Others speculate that the recent global warming may be a blessing in disguise, big-time, by moderating the negative consequences of what might otherwise be a deep chill following a deep crash. During the Little Ice Age, scientists estimate, global temperatures on average may have dropped by less than 1 degree Celsius, showing the potential consequences of even an apparently small decline. Dr. Weiss prefers not to speculate. He sees the coming crash as an opportunity to obtain the knowledge necessary to make informed decisions on climate change, and the extent to which man-made emissions have been a factor. "Having a crash would certainly allow us to pin down the sun's true level of influence on the Earth's climate," concludes Dr. Weiss. Then we will be able to act on fact, rather than from fear. Lawrence Solomon is executive director of Urban Renaissance Institute and Consumer Policy Institute, divisions of Energy Probe Research Foundation. CV OF A DENIER: Nigel Weiss, professor emeritus of mathematical astrophysics in the University of Cambridge, discovered the process of "flux expulsion" by which a conducting fluid undergoing rotating motion acts to expel the magnetic flux from the region of motion, a process now known to occur in the photosphere of the sun and other stars. He is also distinguished for his work on the theory of convection, and for precise numerical experiments on the behaviour of complicated non-linear differential equations. Nigel Weiss is a recipient of a Royal Society Citation, he is a past President of the Royal Astronomical Society, and a past Chairman of Cambridge's School of Physical Sciences. He was educated at Clare College, University of Cambridge. --------------------------------------------------------------------------------------------- Obviously Exxon must have paid Weiss big bucks to slot in that paragraph I marked in red.!!! Everyone who is not paid off already knows exactly how much CO2 affects the climate and that global warming has nothing to do with the sun. Dave Fallschirmsport Marl

I suppose for tandems and high pulling solo's they can afford the extra wait before exiting after freefliers because if all goes to plan they will have enough altitude to get back from a long spot. If all does not go to plan, the extra wait will give them enough horizontal separation to avoid collisions. One other thought, it appears to be a struggle sometimes to get 22 jumpers out of an otter in one pass. How did you get all 400+ out on the world record in one pass? Dave Fallschirmsport Marl

??? Extra margin of saftey in respect to exit separation. Does that make it clearer? "does not give them any extra margin of saftey" Of course it does... If they are relying on vertical separation it is an accident waiting to happen. Dave Fallschirmsport Marl

The height at which AFF and Tandem intend to deploy only gives them a better chance to get back to DZ on a long spot. It does not give them any extra margin of saftey. A freeflier that jumps before them can still have a premeture deployment and the Tandem/AFF can still have a mal that puts them lower than expected. AFF can take a long time to exit, tandems can be very quick. Wings suits can be so all over the place that they should plan their flight to avoid other jumpers. CREW can exit anywhere during the jump run, although it is normally first or last. Dave Fallschirmsport Marl
-
A question, where you jump, do freefliers exit before or after AFF students? AFF level 1 is not much different that a 3-way RW group. Tandems tend to exit after FF'ers. What are your thoughts about this? I do not notice much difference between the freefall speeds of most Tandems and RW Groups. Dave Fallschirmsport Marl

I see it this way. If there really are scientists that can be bought off by Exxon then there are scientists that can be bought off by other people. From what runs in the media I get the impression being bought off by the CO2 crowd is far more profitable than being bought off by Exxon. Dave Fallschirmsport Marl -
We teach our FJC in German, it being a German DZ and all. We teach, literally translated, "last turn is left". What is known as a left hand pattern by you guys. Of course that can be confusing if you make the penultimate turn right, and the last turn left. It works for us though. As a side note, we also experimented with a left hand pattern when the wind was coming from the east, all other times a right hand pattern. A little like Perris, different patterns for different wind situations, mainly to keep traffic away from the runway. After a couple of years, this was abandoned as all to often the jumpers forgot which pattern was in force and we hand them doing both patterns at the same time. Scary. Dave Fallschirmsport Marl

Also like those assholes that said we could never travel faster than 25mph, those that said if you sail to far west you will fall of the edge of the world and if the women sinks she not a witch but if she weighs the same as a duck she is a witch. As time goes on we understand more about our environment, but I am sure that people far into the future would laugh at things we are doing now in the name of science. Dave Fallschirmsport Marl -
