Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Modifying coal power plants is easy:  The scrubber that removes SO2 by reacting it with lime doesn't remove anything else of note, so you just take it out.  The problem is that you don't want SO2 in the lower atmosphere.  It doesn't stay there, instead it causes smog and gets washed out as acid rain.  Bad idea.

Neither forests, deserts nor soils are carbon sinks, only (very limited) carbon stores.  To remove CO2 from the atmosphere, you have to create organic matter and then bury it.  As a first step in that direction, do not use recycled paper.  Making paper and burying it in landfills is the only human-caused process that puts carbon back into the earth.

Earth will never become comparable to venus.  Our oversized moon prevents earth from accumulating such a thick atmosphere.  Also, please try to stay reasonable.  We're talking about 380ppm CO2 on earth while venus has 965000ppm CO2.

Good points all.  Thanks.

The Venusian reference was irresistible, but, as you say, an exaggeration.
