I've never been convinced that this is a valid comparison. The "Global Cooling" concept lasted a few years. Global Warming has been around nearly 2 decades now, and the evidence seems to be mounting (at least for the most basic concept - that Earth is getting warmer). Also the science of Ecology was a much newer field, with far fewer scientists doing the research, and the complex mathematics needed to describe and model a complex system were relatively crude.
Science does change over time (Al Gore -perhaps not seeing the irony- said as much at the start of An Inconvenient Truth), but so far it has always been scientists who have been able to fix the mistakes (as in the case of Global Cooling) and there is ample reason to believe that at some point they do get it right (or right enough for government work - the atomic model is a classic example).
