Mars on the other hand is much smaller than Earth and has a much thiner atmosphere. More sunlight gets through but it is farther away from the sun so receives less than half the sunlight that Earth does at the surface and it has less clouds to trap the energy which makes it very cold.
Mars currently is going through a Global Warming of its own and it would be interesting to see if Venus has also had an increase in temperature. If all the planets are showing an up tick there may be a reason to believe that an outside factor namely the sun is responsible for much of the warming. (It was hard to keep a straight face writing that) No, the sun responsible for warming? Now get the hell out of here! lol
The one thing that we do know is that the Earth has been significantly warmer in the past. So much so that no ice caps existed at the poles and we did not face a run away green house effect. Earth has also underwent extreme levels of volcanism and that didn't do it either. Earth has been hit by extinction level impacts from space and that didn't trigger a run away green house effect. If those things didn't do it we certainly aren't going to. We may wipe ourselves out and even most of the life on the planet (though I doubt that) but Earth will recover and survive as if we never existed at all.
All that manufacturing on Venus and Mars sure f***ed them up!
I guess those Martian and Venusian SUVs were very active 5 billion years ago...
It is still President Bush’s fault!
Premise #2: Climate of Mars suffered catastrophe millions of years ago, and the planet lost it's atmosphere. Using advanced computer models, scientists are discovering that climates are much more complicated than they had thought.
Premise #3: The Earth has seen temperatures go up a degree or two over the last hundred years or so.
Conclusion: Mankind is destroying our planet through industrialization and we need to dismantle our economy and live in harmony with nature.
Simply a lie. We do not know how either Venus or Mars started. Just another GW pantload.
Were there SUVs on Mars and Venus?
People who don’t believe in “martian-made” and “venetian-made” global warming are no different than Holocrust deniers.
Then they say:
"As Earth warms in response to manmade pollution, it risks the same fate."
If the warming before was caused by the sun - why is it such a stretch to think that it may be this time also?
This isn’t so complicated.
Venus is too close to the sun.
Mars is too far from the sun.
“Water vapour is a powerful greenhouse gas and it caused the planet to heat-up even more. This is turn caused more water to evaporate and led to a powerful positive feedback response known as the runaway greenhouse effect”
OK. So how in the world did the Earth recover from the balmy days of the dinosaurs, when there were no icecaps and the oceans were apparently well over 100 deg. F in places? There was absolutely a LOT more H20 in the atmosphere then...
(Possible hint: There is no such thing as 101% humidity.)
Conservative Capitalist Christian Republicans are responsible for Galactic and Universal Warming?
Arguably all three planets are equally subject to the effects of a single cause, solar heating. So why, in the case of Earth, do we insist that human activity is the principle cause of climate change? Jeepers, it appears that Jupiter and even Pluto have heated up in fairly recent times -- that is, at a time when solar activity has been off the scales....
Of course, there's not much science can do about solar activity: We just have to grin and bear it.
Of course, to acknowledge that fact doesn't provide much of a rationale for applying for a research grant geared to "fixing" global warming!
It seems we need to be doing more research on the sun....
Thanks for posting this, Maelstrom!
In fifty or a hundred years, we will know whether taking today's climate models to make political decisions restricting freedoms were right; -- but if they are wrong, by then it may be too late to restore our liberties.
Will the Ice Age Return?
The world is cooling — helped by man
Some scientists are convinced that the world’s climate is getting colder every year, threatening a return to the conditions of the last ice age, which reached its peak about 18,000 years ago.
[...]
From 1890 to 1940 worldwide temperatures rose about 0.18F every 10 years. Some animals extended their ranges northward, the sea was less frozen than before, and icebergs from Greenland did not penetrate as far south.
Since 1940 temperature has been dropping. According to a survey by the National Oceanic and Atmospheric Administration, the average ground readings for the northern hemisphere have, in the years from 1945 to 1968, fallen by one-half degree F. In the United States, east of the Continenal Divide, temperatures in the last decade averaged one to four degrees cooler than in the past 30 years.

[The notion that cooling is being helped by man appears only in the subtitle of the article. Nothing in the article suggests how man might be accomplishing planetary cooling.]
What is the warming situation at Gliese 581?
We need a “Global Alarmist” superhero much like “Captain Obvious” to post with every “the sky is falling” article as they seem to be increasing in frequency during the latest media push on global warming.
Catastrophe?
On worlds like Venus and Mars?
OH PLEASE.
Why stop there? Titan and Europa too!
Jeez man. They are extreme worlds because that is their natural state. It is not a “catastrophe” that Mars is Mars.
Guess those Venusians and Martians didnt buy enough carbon offset credits. Bet they wish they had had their own Gorical!
