The Bosch reaction is a chemical reaction between carbon dioxide and hydrogen that produces elemental carbon (graphite), water and heat.
The overall reaction is as follows:
CO2(g) + 2 H2(g) → C(s) + 2 H2O(l)
The above reaction is actually the result of two reactions. The first reaction is a fast one.
CO2 + H2 → CO + H2O
The second reaction controls the reaction rate.
CO + H2 → C + H2O
The overall reaction produces 2.3x103 joules for every gram of carbon produced at 650 °C. Reaction temperatures are in the range of 450 to 600 °C.
The reaction can be accelerated in the presence of an iron, cobalt or nickel catalyst. Ruthenium also serves to speed up the reaction. The production of elemental carbon tends to foul the catalyst's surface, which is detrimental to the reaction's efficiency.
Together with the Sabatier reaction the Bosch reaction is studied as a way to remove carbon dioxide and to generate clean water aboard a space station [1]
Thats from wiki here is the link

Now if this reaction requires 450 - 600 degrees to begin there is a vast area of the atmosphere in which it would occur. This would break the CO2 down into good things and also create heat to help some of the remaining CO2 obtain escape velicity. Also with the water added to the atmosphere we could add sulphur metabolizing bacteria (here is a link to a google search on those http://www.google.com/search?hs=qFE&hl= … tnG=Search ) to begin ridding the atmoshpere of the sulphur and sulfuric acid. Once the sulphur metabloizing bacteria begin to thrive and reduce the acid we can then begin adding photosynthesisers to the atmosphere to begin converting the CO2 into O2.Coupling all this with mechanical means of reducing the CO2 it should do something real fast.
No I'm not that great at figuring out my own formulas.
Well one way to make Venus shed its atmosphere is to make it hotter. Once the CO2 in the atmosphere reaches a higher temprature it will move faster so just heat it up enough that the CO2 can reach escape velocity. The Bosch and Sabatier reactions are also good ones but require a large amount of hydrogen and a catylst to be imported from elsewhere which is cost prohibitive.
Well when we develop the engineering technology to actually make the atmosphere of mars livable I'm sure if mars turned out to be desert we would have the engineering capability to change that. Maybe canals and artificial rivers. Or even a continent wide artificial rain system using pipes and sprinklers.
One cannot claim ownership of Mars because one cannot enforce its ownership in person on said planet. If NASA went to mars tomorrow (I know its not possible its just an example) If none of your representatives are actually on Mars to enforce the laws then the U.S. can do whatever it wants and there's nothing you can do about it. Not only that but there are at least 4 other people claiming ownership of Mars including a company that actually sells plots of land. So in order to prove you run Mars then the first step in proving it would be to sue that company for everything its got. Of course finding a court that will do it would be nearly impossible. Not to mention if you sued via the "martian court" how would you enforce the terms of the lawsuit without breaking any Terran laws.
A faster rotation would also work to throw off some of the atmosphere. Venus's gravity is only 80 something% of earths and one big reason for it retaining so much atmosphere is the fact that it spins so slowly. Otherwise one would expect earth with its higher gravity and magnetic field to have a much higher atmospheric pressure than venus. Just think of all the volcanic eruptions and all the gas emmisions from people and the few comets to hit earth all these release large amounts of gasses into the atmosphere. Now the earths magnetic field helps the earth keep from losing large amounts of its atmosphere by protecting it from solar winds. Venus does not have that luxury.
I think the biggest issue will be the volcanos. We need to shut them off, our they are just going to keep spitting out gases we are trying to get rid off.
The few probes that were able to penetrate the atmosphere of venus and land for a few minutes saw no evidence of volcanic activity.
Import 0.8x10exp20 kilograms of hydrogen. This is 80 000 000 000 000 000 ( eighty quadrillions of metric tonnes ) . Via Sabatier process ( http://en.wikipedia.org/wiki/Sabatier_reaction ) using cheaper nickel cathalyst turn all the 4.4x10exp20 tonnes of the present CO2 atmosphere into 160 quadrillions of tonnes of methane and 360 quadrillion tonnes of water. The water will be 1/4th of the earth`s total hydrosphere mass - perfect for shallower and wider venusian global ocean ( 80% surface coverage?). The methane , polymerize via http://en.wikipedia.org/wiki/Fischer-Tropsch_process , into heavy oil, asphalt, oil shale, even better kerogen ( http://en.wikipedia.org/wiki/Kerogen ) - pretty stable solid... suitable for storage underground. In kerogen form it will hold the hydrogen and wouldn`t burn after oxigenation of the atmosphere[url]
Though moving that much material would be very costly that is still maybe one of the most brilliant ideas I have ever seen about terraforming venus. Oh and dont forget that sulfuric acid is H2SO4 so there is a lot of hydrogen ready for the taking.
There are several layers of clouds many kilometers thick composed of sulfuric acid.

Or just add enough ammonia (imported from uranus or neptune) so the acid and base neutralize each other becoming NH3(g) + H2SO4(l) → NH4HSO4(s, l) (ammonium bisulfate). Right now I am having a very difficult time figuring out what to do with the ammonium bisulfate and how to seperate it into N2 and H2O and O2 (i'm not a chemist) but it would reduce the atmospheric pressure a lot and I do know that ammonium bisulfate is water soluble.
only thing wrong with that is if anything goes wrong then an entire city of people will fall into venus and die of various horrible causes.

Well if you wanna smash an asteroid into venus here's a list of asteroids nearby.
More Nitrogen is great because nitrogen needs to be present in the soil in order for plants to grow therefore peanuts are great plants for venus because when penuts grow they fix nitrogen from the atmosphere into the soil. Now as for removing the atmosphere why not just blow it off not with nukes because we dont want that radiation but with things like MOAB's and anhydrous ammonia. did you know that a tank of anhydrous ammonia commonly found in the midwest has the explosive power of a hydrogen bomb. not only that but anhydrous ammonia bombs would react with the many kilometer thick cloud of sulfuric acid on venus resulting in a large amount of salt with water sulfuric acid is N2SO4. But with massive explosions all over the upper atmoshere you could accelerate the CO2 to escape velocity in no time.
