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

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.

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.

"Yeah, so much for his grant. Oh, wait, he's from Russia...

Then he won't get any grants from Putin, who is just tickled pink that he can sell carbon credits to Europe and the USA (Not Canada now, because Harper has just made a "made in Canada, clean air in Canada solution which doesn't require sending Canada's wealth to Russia as he stated a couple days ago) while building one of the worlds largest oil refineries and gas pipelines.

But the left wing global warming conspiracy is such a money maker and fear weapon for the left wing socialist democrats and their brain washed constituents that it may be impossible for them to admit the truth as their love of money and power is insatiable.

"You may want to read that article a little more critically. Most of the data used is based on computer simulations. You can get any result you want in a computer simulation by modifying your inputs."

You mean like the computer models that global warming alarmists use, which ignore things like OXEGEN, atmospheric moisture levels, actual measurements of temperatures, as well as observations such as a net GROWTH of mass and total square miles of BOTH polar ice caps?

[Beowulf]

More evidence from the solar system in support of the fact that the sun is the most important variable of temperature anomaly and climate.

True justice would only require that all left wing socialist global warming deceivers like Al Gore be returned to the respective nations of their forefathers and be tarred and feathered before putting them off the ship and onto the land they came from.

[Alissa]

This is the picture that says it all for me - and Al Gore thinks man causes global warning - there are way too many idiots out there!

[rickylc]

You, of course, realize that UCAR's existence depends on GW being a human caused event. That wouldn't color their conclusions, would it?

Yeah, right!

ha, wouldn't trust a thing these guys put out.

[driftdiver]

"We should send AlGore to Mars to do further research."

Commercially or on a private spaceship? The carbon credits for that trip on a private ship would be enormously expensive.

Here is a link to a fairly short explaination of the global warming con: Global Warming Swindle.

Partly true, and yes I think their statements in the article about human are biased and irrelevant. But there are other measurements of solar activity including irradiance that show increases too small to explain much warming (I have to find the links). I trust the science they put out more than the Russian guy that started this thread who seems to be quoting the same information about 3-4 years of Martian warming that everyone else is. 3-4 years means almost nothing in climate change.

[Nathan Zachary]

What they do is effect cloud cover, which have a greater effect of atmopheric temperatures.
We do btw, have warm and cold cycles every 22 years, every 10 years in fact. They coincide with wet and dry cycles. These cycles vary regionally, for instance, it may be dryer in southern regions, while it's wet in northern regions, east and west.
If you were a farmer, you'd be more aware of this wet/dry cycle. After several decades of farming, you'd see a pattern emerge when you realize that every ten years or so, you can actually plant crop in that swampy area, that it slowly shrinks each year, then expands, as moisture decreases and increases in a ten year pattern.

Spring flooding is another example of shorter and longer term weather cycles. Once every hundred years, we get the flood of the century,, then there as smaller spikes of extreme flooding every 25 years, and still smaller spikes every 10, and very dry periods in between, where there is barely any sping flooding at all, and water reserves begin to dry up, causing "global warming" fantics to take pictures of these dry regions (while ignoring the flooded regions)
and pictures of receeding glaciers (while ignoring the expanding ones)

You agree that an accurate model of all factors contributing to climate change cannot be artificially made due to lack of data, yet the same intellectually dishonest "may cause" junk science proponents use.

[Overtaxed]

Well Al's got money. He can trade in some of his carbon credits for use of a private spaceship.

Or you could just forget carbon credits and use a nuclear powered rocket.

Cosmic rays trigger cloud formation, which leads to cooling. The theory is that an increase in the sun's magnetic field diverts cosmic rays, reducing cloud cover and increasing warming.

[Nathan Zachary]

" Did Mars experience the same drop in temperatures between 1945 and 1975? Somehow I doubt it."

So do, simply because mars is futher away and would take longer for the solar radiation effecting earth to reach it.

[randog]

Why do you doubt it?

[palmer]

The measurements of solar output have also been measured, not just modeled as in the article I linked to. Measurements of solar irradiance don't show enough increase to explain much warming. The highest likelihood is separate earthly and Martian factors are involved in the warming.

Thanks, I think I stated it backwards above.

Only a few minutes longer. The sun's changes undoubtedly affect both planets in various ways, but there should be no appreciable lag in changes.
