CrakrJak: I'm afraid you dropped the ball on Venus, somehow failing to mention the fact that the greenhouse effect is key to understanding the planet`s history.

For a scientific treatment of the topic, I recommend this short article written by two planetary scientists associated with NASA`s Ames Research Center.

patch: You mention a 'tipping point`, only you neglect to mention where that point is. I know where they`ve estimated that it is, and it`s 4ºC higher than it is now. Our current warming `anomaly` is around a mere 0.2ºC and at it`s highest point, a decade ago, it was 0.8ºC We are nowhere even close to their own estimated `tipping point` and because of this lull in the solar cycle it`s not likely it`ll get any closer.
Fools: First off Venus is much too close to the sun, there is no evidence it ever had much liquid water on it`s surface. The vulcanism on Venus never stopped spewing out sulfur dioxide which begets strong sulfuric acid for `rain`. Venus never had a chance to be like earth. Mars may have once had liquid water on it`s surface and a decent atmosphere, unfortunately it lost it`s magnetic field and even scientists are puzzled as to why. Earth`s magnetic field protects us from much of the Sun`s radiation, Mars lost that protection and thus lost it`s atmosphere

Perhaps Crakrjak can explain why Venus is hotter than Mercury, despite the fact that Mercury is much closer to the Sun. It couldn't be because Venus has an incredibly high amount of CO2 in it`s atmosphere, could it?

I suppose it would all be ok if Venus had some plants to absorb all that CO2, right?

Addendum: That last comment should have said pH "lowered", not raised, my goof.

Algae is the largest CO2 to O2 conversion plant life on Earth. 90% of the oxygen made comes from algae. Algae are the lungs of our planet and it's doing just fine.

Well seeing as how since the industrial revolution the pH of oceans has increased by 0.1 of a unit, and remembering that pH is a logarithmic scale, that means that the oceans are 30% more acidic than before the industrial revolution. Sure there are types of algae that thrive in acidic conditions, but those are usually near estuaries and land in general. This will be worse near the poles since cold water retains more CO2, and algae there are food for many larger organisms. Who knows when we go over the tipping point and then can`t do anything about it. Better to do something now instead of being caught with our hands tied behind our backs later.
