   CAMBRIDGE, Mass., Nov. 9 , There is now ,no doubt, that some of the effects of human-induced climate change could be offset with engineering fixes, according to David Keith, an expert on climate and energy at the University of Calgary.
   
   But what action should be taken, based on this knowledge?That was one of the knotty questions he and other experts wrestled with at a two-day conference that ended here on Friday.
   
   Dr. Keith, an organizer of the conference, said that at one time he thought scientists should not talk in public about ,geoengineering, remedies for global warming , like injecting chemicals into the upper atmosphere to cool the poles, or blocking sunlight by making clouds more reflective or stationing mirrors in space.
   
   Like many other researchers, he explained, he worried that the potential for a climate fix, even an imperfect one, would only encourage people to continue the profligate burning of fossil fuels that got the planet into trouble in the first place.
   ...
   ,Will there be some consequences you don,t like?, Dr. Keith said in an interview. ,Of course.,
   
   Also, as several researchers noted, engineering a cooler earth would do nothing for other climate-related problems, like the way accumulating carbon is making the oceans more acidic.
   
   And who should decide what action should be taken or when?
   
   ,I have no idea,, Dr. Keith replied.But just as international organizations were formed to regulate the use of radio frequencies, organize air traffic control, track space debris and deal with other problems, it might be possible to create an international organization to deal with these questions, he said.
   
   ,We are backing our way into global governance, very slowly,, he said.
   ...
   One way or another, Dr. Keith said, in 200 years the earth will be ,an artifact,, a product of human design.
