Why are some people so quick to claim extraterrestrial global warming while at the same time denying global warming on Earth?
"The evidence for Jupiter’s global warming is nothing of the sort. It is evidence that there are warm spots, with storms rising to the tops of the clouds. This may just be a local effect, and not global. Jupiter’s atmosphere is fiendishly complex, and not well understood. If you’ve ever looked at the planet through a telescope, you can clearly see thick horizontal bands across the disk; these are enormous wind patterns that dwarf the Earth. A few years ago, one of the dark bands disappeared completely. For reasons unknown to this day, it sank a bit in the atmosphere, and opaque clouds covered it up. I saw it many times through my ’scope, and it was bizarre. Then, after a while, it reappeared, just like that. My point: any claims about Jupiter’s atmosphere when it comes to global warming must be approached very carefully. We don’t understand the dynamics of that system."[1]
Edit, Note for Mr Krinkle: You really need to work on your reading comprehension; from your article:
[Quote] “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. (Related: "Don't Blame Sun for Global Warming, Study Says" [September 13, 2006].)
“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.” [End quote]
