Man Made Global Warming is a Hoax!
Jupiter
A new storm and a new red spot on Jupiter hints at climate change, USA TODAY and dozens of other sources explained yesterday. The temperatures are expected to change by as much as 10 Fahrenheit degrees at different places of the globe. At least close to the new spot and to the equator, nothing less than global warming is expected.
New observations of Jupiter's climate change were released in 2008
Neptune
The climate of Neptune - more precisely its reflectivity - was recently changing. Lockwood and Hammel argue in Geophysical Research Letters, vol. 34 (2007) that the trends on Neptune reveal suggestive correlations of brightness of Neptune with the temperature trends on Earth, indicating their common solar origin - although I am not quite sure whether the sign is as expected.

Triton
Triton is Neptune's largest Moon. Some people believe that it used to be an asteroid. Global warming was detected on Triton. Between 1989 and 1998, the temperature jumped by 5 percent on the absolute (Kelvin) scale. The same relative increase would raise the Earth's temperature by 22 degrees Fahrenheit in 9 years. See thousands of other pages about the global warming on Triton.
Enceladus
Another moon of Saturn's, Enceladus, would be also expected to be frozen and cold. Suddenly, Cassini has informed us that Enceladus generates its own heat. Its high temperatures seem to be incompatible with calculations based on solar energy itself, according to existing models.
Saturn
Saturn itself has a rather warm southern pole, and the temperatures in that region suddenly jumped by 3-5 Kelvin degrees. Well, it's warm because it's been exposed to sunshine for quite some time but the magnitude of the temperature jumps is not trivial to calculate.
Pluto
What's going on with Pluto? Well, yes, your guess is right. There is global warming on Pluto. Pluto's atmospheric pressure has tripled in 14 years, and the associated increase of temperature is estimated to be around 3.5 Fahrenheit degrees, despite the motion of Pluto away from the Sun.
Mars
Of course, the global warming on Mars is a well-known story. Between 1975 and 2000, Mars warmed up by 0.65 Celsius degrees, much faster than Earth: see Nature 2007. The warming has been used by this blog to discover the Martians. More seriously, we have explained that the dramatic and speedy melting of the Martian icecaps is caused by the greenhouse effect. 95% of "their" atmosphere is made of carbon dioxide; that's slightly more than 0.038% of our atmosphere.
The warming trend on Mars is undeniable. Some people have tried to blame the global warming on NASA's rovers. Such accusations are pretty serious because NASA is already preparing plans to occupy Mars using the greenhouse effect.
Venus
This planet doesn't belong to this list of planets where recent warming has been demonstrated. But it is interesting to talk about the greenhouse effect there.
Venus, our planet's evil sister, has already been identified as unusable for life because of ... yes, because of the greenhouse effect that occured in the past. Last month, the Venus express gave us some new hints why Venus has such a thick atmosphere that generated global warming.
Venus' distance from the Sun is about 70% of the distance Sun-Earth. Because of the second power, this means that there is twice as much solar radiation per area over there. Because of the fourth power in the Stefan-Boltzmann law, it means that you expect about 20% higher temperatures in comparison with Earth on the Kelvin scale which would mean, if Venus were a black body, that the temperature would still be still below 100 Celsius. But they are about 470 Celsius on Venus.
Venus is clearly not a black body and the greenhouse effect is important for raising its temperature. But you should notice that Venus' atmosphere has 90 times higher pressure than the terrestrial atmosphere and 96% of it is carbon dioxide! The Earth only has 380 parts per million of CO2, and if you divided it by 90 to get the corresponding fraction of the Venus atmosphere, you get about 4 parts per million. There is more than 100,000 times less CO2 density here than on Venus! If you used a linear relationship between the CO2 concentration and temperature boost, you would see that the expected increase of the Earth temperature due to CO2 is 400 Celsius divided by more than 100,000 which is a few millikelvins - a totally negligible amount! The actual strength of the greenhouse effect on Earth will be stronger - because the first molecules matter more - but it won't be exceedingly stronger. At any rate, when numbers are taken into account, you shouldn't expect any substantial influence of CO2 on Earth.
But let us return to the planets that are known to be currently warming.
Earth
The Earth is currently experiencing warming, too, although a less dramatic one than the previous examples. However, there is apparently a huge difference. The warming on the previous planets and moons was natural. On the other hand, the warming on Earth couldn't evolve naturally: it is caused by the humankind, evil corporations, and their intelligent design, most left-wing scientists believe. The warming trends can't have anything to do with the Sun whose activity is now highest in the last 1000 years: it is unethical to propose that the Sun plays any role, consensus scientists argue.
