We absolutely NEED the greenhouse effect to live on this planet. Otherwise we would freeze every night. The greenhouse effect is precisely one of the reasons this planet is habitable. Being a science minded person, I often question any hypothesis that is claimed to be absolute prior to the elimination of all others. Science is often more about disproving things than proving them. I won't jump on either side because I don't he enough evidence to make an informed decision, but NASA has said that surface temperatures on Mars have increased at a rate comparable to those of Earth(and Mars has no greenhouse effect). Being that we are planning on making a manned Mars mission sometime this generation, a lot of research has been going into studying Mars and it's similarity to Earth. Don't be quick to jump on any bandwagon without the requirement of concrete proof.
