...where evidence is lacking for the causes of global warming. it would be too expensive to reduce the release of greenhouse gases at this time. Right?
Can anyone point me in the direction of some websites where i can read up on this. Thanks.

Global warming is a debatable topic from my point of view because the earth has been cooler and warmer than what it is now. Surely soon after the BIg Bang the earth was much warmer than now? Therefore it is possible to say that global cooling is occurring. In recent Geological times that global warming is happening, as represented in the graph in the link below. While looking at the graph, you will notice that the globe did not warm between 1940 and 1980. I recall scientists being concerned about the onset of an ice age was near in the 70s. Oh what a life it would be to be a climatologist. One could never be proven wrong in your lifetime.
Having said all of that, at least some awareness has been made about polluting the environment.

As the first answerer alluded, you can't find a reputable site indicating a lack of evidence. In fact, the reputable, legitimate climatologists are fairly unified in claiming mankind's contribution to the current unprecedented rate of onset and predicted degree of warming.
Only those who continue to find the concept of mankind's contribution to global warming as an "inconvenient truth" would suggest that what's currently happening is natural. My guess is those people also continue to believe the Earth is flat.
PS: Answerer Ralph (below), who gave you a link to the global temperature anomalies, is one of those inconvenient truth people. To skew the answer and avoid the inconvenience, he gave you a very short time span graph that hardly tells the story about global warming.
Try http://data.giss.nasa.gov/gistemp/graphs/ for a graph over a longer period. You can clearly see the increase in slope (the rate of onset) and the trend to unprecedented temperatures. There are even longer span graphs, but they tell the same story...this warming cycle is coming on faster and more intensely than ever before.
