I am not sure you stand on this issue, but the skeptics have valid points. What bothers me about the left is that they take the same position they take on every issue, which is that if you don't agree with them you are either stupid or evil. Rarely do they argue the points being made. Instead they engage in character assassination.
The alternative is to attack those opponents on the extreme fringe. This is sort of a straw man argument because it doesn't acknowledge that some people have legitimate arguments. For example, they say that all skeptics deny that global warming is taking place. Maybe a few do, but the real issue is not whether it is taking place, which few dispute, but how much will we get and will it lead to disaster?
When you have politically funded and motivated science, then it is not real science at all Some of it could be, but I question the motivations of at least some of those involved. This is science to push an agenda.
