yup just some guy on the internet

I have ALREADY beaten you in this debate, why would i feel the need to go into it any further?

You raise an interesting point with the Mammoth. Many of these big guys have been recovered almost intact, frozen where they stood. Genetic tests on their DNA demonstrates they are closely related to present day elephants. Elephants are strictly warm climate animals. They require huge quantities of food each day and their tusk are totally unsuitable for rooting out food in a frozen turf.
So how did they boys stay alive? The answer is that their range used to be far warmer and more tropical than today. We are talking about Siberia and Alaska looking more like India. And many of these Mammoths have been dated to about 4,000 years ago. So tropical Siberia was not all that long ago. This temp change happened rapidly.
Any temp change today is part of one of the hundreds of heating/cooling cycles that earth has gone through.
The global warming hysteria is all about a new worldwide tax and has zero to do with temp change.

you have been proven wrong.............no need to further humiliate you at this point? you said something could not be done Myself and others have proven you wrong Period......
you didnt "Rip It to shreds " the first time around?
why do you insist on trying to justify yourself its quite pathetic
roker. You know and I know, and everyone else knows that if you had anything at all with which to slap me down, you would bring it forward and print it in red all caps. The fact that you haven't done so is proof positive that you are just talking through your hat.
anyone reading this thread in its entirety KNOWS that YOU Palerider told Stevox a few things about lasers and made fun of him ......
Roker, flat out proved your assumptions wrong, Provided corroboration, and references from a NASA scientist?
You had your azs ripped by the 10th post of this thread ? what are you talkin about skippy?........page one you were proven wrong !!!! and you have been crawdaddin for 5 more pages?
Funny how you seem to skip things all the time its all here in the thread oh pompus one
roker. You know and I know, and everyone else knows that if you had anything at all with which to slap me down, you would bring it forward and print it in red all caps.
apparently your not exactly right here are you ? what old data are you relying on? It appears that Project orion has in fact been experimenting with moving objects in space and debris retreval as well as "ASTEROID AVOIDANCE" using.................Lasers you might want to look at the last post as well
take a look here at this paper

here are some snippets from the pdf file
=============================
The Author
Jonathan W. Campbell, a Colonel in the United States Air Force
Reserve, is presently assigned as the Individual Mission Augmentee to the CADRE Commander at Air University. In civilian life, Dr. Campbell is a scientist and advanced projects manager in the Advanced Projects Office
of the National Aeronautics and Space Administration (NASA) at the Marshall Space Flight Center in Alabama.
In that capacity he has worked for over 20 years in the space program a number of advanced research projects. He served as the project manager on Project ORION, which was a NASA study published in 1997 that explored the feasibility of using lasers to remove orbital debris. He has published more than fifty scientific
papers on various subjects, including laser orbital debris removal and laser asteroid, meteoroid, and comet deflection.
============================
Claude Phipps suggested the use of laser propulsion with a ground-based pulsed laser as a solution to the orbital debris problem in 1994 (Phipps 1994). The Orion Project, which was a study conducted by NASA
and the USAF in 1995-96, concluded that the concept of using ground-based lasers for removing orbital debris is feasible and cost effective relative to the cost of placing objects in orbit (Campbell 1996). This study
presents an analysis of the debris removal concept, and a plan for developing the technology for removing orbital debris with near-Earth lasers.
This study begins with an analysis of the cost of a laser orbital debris removal system as the first step toward establishing the cost-effectiveness of this concept. This study then investigates the requirements
for using laser propulsion for the diverse ensemble of debris particles in orbit. The following section demonstrates that the adaptive optics requirement for debris removal is within technological reach.
After demonstrating that laser systems can effectively remove debris from orbit with the proper engagement strategy, the study concludes with a proposal to develop the technology for debris removal and advance that technology for laser space propulsion.

III. Near Earth Asteroid Avoidance System
Coupling PALS with powerful telescopes, such as those being developed under the Next Generation Space Telescope (NGST) project, would provide long-term warning for implementation of an overall NEO
avoidance system. The feasibility of this system is discussed below.
The lasers that would he used in Project Orion have demonstrated sufficient capability for orbital debris removal for objects in the size range from 1-10 cm diameter. Ground based experimental data, using a 20 kW
pulsed laser, show that the impulse imparted to aluminum targets due to the ejected plasma cloud gives an average surface pressure p = 6.5 x 10-4 N/cm2, or equivalently, an acceleration, a = l.25x 10-6 m/s2 With present technology, a laser phased array can be aimed at the asteroid with sufficient power to ablate its surface. Assuming that a laser array can be
scaled up to operate on a 1 km diameter iron asteroid, this would require a 200 GW power grid.
Several alternate potential power sources are
available, including nuclear or electric generation and solar power arrays. Let us assume that the asteroid is at infinity moving toward the Earth with a velocity v0 and impact parameter R. The closest point of approach Re is given by ...
raed the rest in this interesting nasa related document
palerider, as for your "laser can't move anything" comment, you hsould research before you post. See the article "Research Paper Illuminates How Light Pushes Atoms" at http://www.sciencedaily.com/releases/2006/08/060819112154.htm
