The CO2 in Venus' atmosphere could be used as a source of carbon for building a ribbon around the planet. A satellite-based atmospheric heater could perhaps propel the gas to sufficient altitude. The oxygen could be combined with hydrogen so that vapor clouds formed on Venus, since those reflect a lot of sunlight back into the atmosphere. There might be enough hydrogen in the solar wind for this to be done reasonably quickly.
It could be sensible to build an orbital ring/space station around Venus while we wait for the planet to cool...
Quite glad to see that Mars doesn't get all the Terraforming attention! =)
