cyanne, the question was about scientists... and the answer is???
NO
No reputable scientists try to refute the human causes of global warming. To clarify, the debate is only among lay people, not those who study the atmosphere or climate. There is no scientific doubt that humans have a large influence on global warming. They are not the sole cause, that is well known, but humans are a major contributor when it comes to global warming.

Yes, there certainly is.
There has also been politically motivated editing of scientific reports to justify both standpoints in the debate. The worst case I know of was to support the argument that humans are responsible where the phrase "are not responsible" was edited to "are responsible".
Climate models are notoriously complex. Think about it - the weather forecast is pretty good for the next 3 or 4 days, but more or less falls apart beyond that. To model climate change you are equivalently asking for the climate model to accurately predict the weather over a period of 100 or more years.
However, there is no real controversy any longer that climate change is occuring and that it is occuring at a faster rate than has been the case at any stage in the planet's history other than catastophic events such as the mass extinction of the dinosaurs.
This leads to two conclusions:
1. it is unlikely to have a natural cause
2. it is serious
The coincidence of climate change with insustrialisation is hard to ignore.

Yes, there most certainly is. Have a look at any recent science journal and you will see a diversity of views.
“These results suggest that 20th Century warming trends are plausibly a continuation of past climate patterns. Results are not precise enough to solve the attribution problem by partitioning warming into natural versus human-induced components. However, anywhere from a major portion to all of the warming of the 20th Century could plausibly result from natural causes according to these results.”

No. All mainstream, ie university, scientists are convinced by the data that GW has a significant human input. That's not to say it's not overlaid on a natural phenomenon.

Yes, even today there is some controversy about it.
