I would guess this new computer modeling could be used to predict future climate changes or possibly weather patterns. Also, there usually aren't vast scientific conspiracies, since scientists are usually just as happy to be proven wrong as to be proven correct. If scientists say there is a 95% probability that not only is global warming real, but that humans are responsible for it, then its probably the case. Dissenting evidence will be presented and peer reviewed, to bury any such evidence is unethical, and most scientists wouldn't even consider doing it.
