How do you differentiate...
...between "GW research... done by people predisposed and/or motivated to find evidence FOR GW" (and I assume must be disregarded on those grounds?) and GW research that happens to find evidence for GW?
Personally, I think GW is certainly an alarming prospect, but... If we really plan to double the amount of CO2 in the atmosphere, in the next 100 or 200 years, GW may end up being the least of our worries. That's a huge difference to make in our atmosphere and nobody knows the ramifications.
