Do you want the Google Earth pic?

Well look at that 2400 miles, 17.000 up rus

Oops. My bad. I was looking at 135 E and measuring in the other direction :-?

The point remains. If you take the same exercise, and draw a line through the magnitude from 4000 km, you get a very small amplitude. Also, the ice began to break up well before the earthquake;)

My mistake, so the collapse caused the earthquake. Did any seismic stations record the collapse?

It could have caused the quake. That's hard to say. But I would bet more on plate tectonics. That whole ring of fire thing ;)

At the same site you linked to, they give this image for all quakes in the last 8-30 days.

The version I saw was in a list, several in the area on the 6th. Was it at low-tide when it broke, or should I look it up?

I looked it up, didn't have much luck. There's an Australian government website, but I couldn't get a reading close enough.

Well the obvious answer is they aren't. I expect you knew that. Maybe you should just use a magnifying glass and burn your straw man already. An activity which includes the sun (hooray!) and that's really what has been the primary warming signal, right? :p

Wow, what an angry response :lol:

But I still can't help but notice you have no defense for your delusions.

What is happening is completely natural. We're still coming out of the last ice age. The poles are warming not the world. It isn't just happening here but across the solar system. This global warming isn't expected to effect the tropics, so then how is it global? It isn't! It's solar.

Jeebsus! Better get yourself some tinfoil and make a hat :roll:

Not at all. Sarcasm isn't angry, I thought it was funny:smile:

What delusions of mine? I was responding to yours ;)

So, maybe you can answer this then. How long have these measurements of warming existed for Mars specifically? What is the standard period for measuring climate? Do you know why? Solar, that old nugget. Perhaps you can find a trend for solar activity since 1975. What does it look like? More importantly, how does that trend correlate with the temperature trend?

I wear a wool toque. It's warm.

That's good to hear. Now maybe if you can figure out why you think what you do, you might actually be able to make an argument! Instead of trying to leap the sarchasm :lol:

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says


Excerpts from:

February 28, 2007

Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human-induced—cause, according to one scientist's controversial theory. Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.

Mars, too, appears to be enjoying more mild and balmy temperatures.
In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.
Habibullo Abdussamatov, head of space research at St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.
"The long-term increase in solar irradiance is heating both Earth and Mars," he said.
Solar Cycles
Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets.
Mars and Earth, for instance, have experienced periodic ice ages throughout their histories.
"Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said.
By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars.
Abdussamatov's work, however, has not been well received by other climate scientists. [Obviously his beard isn't long and gray enough.]

Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that "the idea just isn't supported by the theory or by the observations."
Planets' Wobbles
The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by changes in the sun.
"Wobbles in the orbit of Mars are the main cause of its climate change in the current era," Oxford's Wilson explained.
All planets experience a few wobbles as they make their journey around the sun. Earth's wobbles are known as Milankovitch cycles and occur on time scales of between 20,000 and 100,000 years.
These fluctuations change the tilt of Earth's axis and its distance from the sun and are thought to be responsible for the waxing and waning of ice ages on Earth.
Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now.
"Mars has no [large] moon, which makes its wobbles much larger, and hence the swings in climate are greater too," Wilson said. [Which is funny considering that the entire solar system is warming not just Mars!]

I never said we aren't having an impact but that we aren't having as great an impact as the hysteria would suggest. It is pretty obvious when the entire solar system is warming up that it can't be entirely our fault!!! It doesn't matter how long we have been measuring the temperature in the solar system so long as it has been long enough to know everywhere is warming not just us.

Only this theory isn't absurd it's bloody obvious it's absurd that the scientific community and everyone else can't see that!

As long as it's lined properly ;-)
