Two new reports cast doubt on the manmade global warming theory and instead point to another cause for the recent warming of Earth — changes in the sun.
One report from National Geographic News asserts, "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.”
Data from NASA’s Mars Global Surveyor and Odyssey mission in 2005 disclosed that the carbon dioxide "ice caps” near Mars’ south pole had been shrinking for three consecutive summers.
Habibullo Abdussamatov, head of the Pulkovo Astronomical Observatory in Russia, says the shrinking provides evidence that the current warming on Earth is being caused by changes in the sun, according to the National Geographic article.
"The long-term increase in solar irradiance is heating both Earth and Mars,” he said. "Manmade 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.”
The other report offers a mechanism behind the changes in the sun — variations in its magnetic field.
Compiled by scientists at the Danish National Space Center, it maintains that the Earth’s climate is strongly influenced by cosmic rays from exploded stars.
The cosmic rays help make ordinary clouds, and high levels of rays and cloudiness cool the planet, while lower levels of radiation lead to milder temperatures, according to the Danish report, which is cited by Marc Morano, communications director for the U.S. Senate Committee on Environment & Public Works, on the committee’s Web site.
"Cosmic ray intensities — and therefore cloudiness — keep changing because the sun’s magnetic field varies in its ability to repel cosmic rays coming from the galaxy before they reach the Earth,” the Danish report by Henrik Svensmark, head of the Space Center, explains.
Whenever the sun’s magnetic field was weak, cosmic ray intensities were high and the climate cooled, most recently in the little ice age that climaxed 300 years ago.
Several scientists cited in the report believe that changes in the Earth’s climate are linked to "the journey of the sun and the Earth through the Milky Way Galaxy. They blame the icehouse episodes on encounters with bright spiral arms, where cosmic rays are most intense.”
You should have taken his hand, the one not holding the wine cooler, and placed it on the grill next to the burgers. Then, as he screamed, you should have explained to him that heat is hot.
I would agree. As an aquaintance (as opposed to a friend) once said...in all seriousness; "I know how to solve the global warming problem - just get rid of daylight savings time".
God's truth - he was serious!!
Naw...he'll just call out his DNC Lawyers to sue the sun.
Gore keeps the investors' money, the company goes belly-up, he gets rich(er) and the investors lose. That's the breaks!
Duh. Essentially all of the heat that affects Earth is coming from the sun. The amount of heat that comes from the Earth's interior is negligible. The amount of heat that comes from the start or is reflected off the moon is essentially nothing.
The hear released by machines on Earth is very small compared to the heat that blasts the Earth from the sun.
It's logical to conclude that variations in the heat output of the sun change the amount of heat that reaches the Earth.
The media and left-oriented scientists are doing everything they can to keep us from hearing about the variations in the amount of sun energy that reaches us, due to the Earth's wobble, sunspots, variations in Earth's magnetic field, and other periodic phenomena.
Well, according to the Congress, shifting the time saves energy. And, if your friend thinks that Global Warming is man-made..... He might have an argument. But only in his own head.
That jumped out at me also. Anything suggesting that nature has a had in any climatic change is "controversial". That speaks volumes.
BUMP!
It can be written off as a tax loss.
More Microsoft FUD.
Once you've climbed Mt. Everest, the descent's a piece of cake; like falling off a log.
What amazes me is that only this week have people been noticing news that has been out there for over a year.

Becoming warmer by a couple of degrees would be beneficial for the most part; all the scare stories are based on the premise or possibility of a thermal runaway effect for which there is no precedent.
Turning out the lights, turning down the winter thermostat, riding your bike, paying Jose to grow more weeds or cactus, meeting Aunt Mary in Middleville and following the Pied Piper around like a dumb puppy dog might save resources in the short run but it makes us all look like a bunch of gullible fools.
