Uhm, no. We can still do climate science without the problems, and there will be funds (maybe not as much, but that's ok). Climate is still something we want and need to understand, even if there is no problem at the moment (just imagine another ice age.. )

All the researchers here (Heidelberg) would be happy - euphoric! - to be able to disprove the theory. Just image, you'd be able to tell everyone it's gonna be ok.. but it's most probably not. And there are so many students and grad students working on the data - if there was a problem, can you really imagine that not a single student would be idealistic enough to speak up? (I totally would, but then I might be in already.)

You can download raw data if you want, and look at them yourself. Most projects actually have a data base, and if not just ask. If there is a problem in the way the data has been taken and evaluated, notice the authors. But a lot of people have looked over it already.As I said, everyone would be unbelievably happy if the problem didn't exist. Look here for some oceanic data, for example: http://woce.nodc.noaa.gov/wdiu/
