No scientist disagrees about the greenhouse effect, it is very well known and proven.
Global warming is a different matter however. Virtually all scientists working in the field of climate agree that global warming is a result of human activity, but they have differing opinions on the future effect of carbon dioxide. There will a few qualified scientists who disagree with the consensus, but that's how science works. You prove a hypothesis by trying to disprove it.

There is a very tiny minority of scientists in relevant fields who don't think global warming is happening and is due to the human combustion of fossil fuels.
Some of them are paid by conservative think tanks (and this is documented). Singer, for example, has been on the wrong side of secondary smoking, ozone, and now global warming. As long as he gets his check...
Some of them seem to be constitutionally contrarian, possibly because they'd rather have a small chance of being uniquely right than a large chance of being right in common with everyone else. Lindzen, Gray...
Many are only dabblers in climate studies: They're really specialists in solar dynamics or astrophysics, and are looking for an easy way to apply what they know to a big problem. But often they don't bother to get generally acquainted with the field of study. Soon, Baliunas, Shaviv...
But it is most likely that the vast majority of scientists who are focused on climate science are actually right. As even Richard Feynman, a great and famous maverick in physics, admitted, the "conventional view is probably going to turn out to be right".

They don't disagree with the greenhouse effect. They legitimately question whether the conclusion of global warming caused by human activity is honestly supported by evidence, or just by politics and hype. They think.
It's not a question of whether there's evidence against it. It's a question of whether there's evidence for it.

i don't think that anyone any more disagree with the greenhouse effect specially scientists
you should look more carefully and you will find that...
good luck

No reputable meteorologist or atmospheric scientist doubts global warming any more. I haven't read an article in Nature or Science presenting credible evidence against global warming in years.
