This is amazing.
Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
Don’t Blame Sun for Global Warming, Study Says
Above are links to two articles in National Geographic. One is about a “controversial” scientist (Ellen Goodman would call him a “Global Warming Denier”) who cites evidence from Mars that would seem to show that Mars is heating up at the same time Earth is heating and that therefore the cause of heating is most likely solar irradiance and not man-made causes.
The other article quotes scientists who found that common sun spot activity is not enough to account for climate changes. However, in that same article (which is linked in the “controversial” article as reason for skepticism) it is noted that:
“There are numerous studies that find a correlation [between solar variation and Earth climate],” said Sami Solanki of the Max Planck Institute for Solar System Research in Lindau, Germany.
“These authors have looked at the simplest mechanism, and they find that this mechanism does not produce the same level of change that has been observed,” he continued.
“This could be suggesting that there are other mechanisms acting for the way that the sun influences climate.”
Solar ultraviolet (UV) rays are one possibility, though that theory creates its own challenges.
“UV is only a small fraction of total solar output, so you’d need a strong amplification mechanism in the Earth’s atmosphere,” study co-author Spruit said.
Magnetized plasma flares known as solar wind could also impact Earth’s climate. Solar wind influences galactic rays and may in turn affect atmospheric phenomena on Earth, such as cloud cover.
Such complex interactions are poorly understood but could be crucial to unlocking Earth’s climatic puzzle.
“I think the main question,” the Max Planck Institute’s Solanki said, “is, How does the sun [in general] act on climate? What are the processes that are going on in the Earth’s atmosphere?”
Ok, so let me get this straight. One would think that the SUN might have something to do with climate on Earth, right? And, scientists have found a high correlation between “solar variation and Earth climate”, right? And, there is great debate between scientists who don’t understand the cause of this correlation and admit that “such complex interactions are poorly understood but could be crucial to unlocking Earth’s climatic puzzle”, right? Yet, didn’t they just release a study telling us that it almost beyond reasonable doubt that humans are causing global warming?
I submit that if climate scientists are still at the point of saying things like “I think the main question is, how does the sun [in general] act on climate? What are the processes that are going on in the Earth’s atmosphere?” then perhaps we should have some skepticism as to the validity of their computer models which extrapolate their current understanding and attempt to predict the weather over the next 100 years!!!!!
I will put my prediction of what will happen to humans if we wreck the global economy against predictions based on these climate models anyday.
