On global warming, I question whether or not we have sufficient information to tell if observed warming is the result of man or if it is, perhaps, the result of natural cycles. Here's the thought I end up with, though: it seems pretty clear that some kind of warming trend is underway, and we have pretty good scientific evidence that there will be some nasty side effects. Given that, does it make sense to continue to do things that, if not the direct cause of the warming, could exasperate the situation?

However I do think there is enough evidence to say that the current warming trend is mostly due to human actions.
I can appreciate that there is "wiggle room" for discussion but AFAIK the majority of environmental scientists think that the current warming trend is anthropogenic in origin.
But in something as complicated as global weather there's room for skepticism and discussion, here is an interesting exchange that happened in the pages of Scientific American:
Misleading Math about the Earth
A critique of a book that goes definitely against the current scientific opinion on global warming, the author had a chance to reply to those criticisms:
The Skeptical Environmentalist Replies
This was followed by A Response to Lomborg's Rebuttal
That whole exchange does manage to illustrate several of the details and complexities surrounding this topic.
However, there are way too many reports that make denying global warming quite unbelievable, here are some of those:
