Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says
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.
Climate change is a much, much bigger issue than the public, politicians, and even the most alarmed environmentalists realize. Global warming extends to Mars, where the polar ice cap is shrinking, where deep gullies in the landscape are now laid bare, and where the climate is the warmest it has been in decades or centuries.
The latest images could provide evidence that Jupiter is in the midst of a global change that can modify temperatures by as much as 10 degrees Fahrenheit on different parts of the globe.
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.
Love that paragraph!

We want to continue to support real and civil dialogue for members of our audience: the undecided Canadians and supporters of the Liberal, NDP, Green and Bloc parties who are concerned about another Harper conservative government and are thinking about so-called strategic voting this election.

Look to Mars for the truth on global warming
