Since reptiles are cold-blooded and most inhabit tropical, semi-tropical or desert regions it would appear that global-warming would be advantageous to them. Any opinions?

Not necessarily good for reptiles - definitely not for amphibians.
Rising ambient temperatures are one of the cited reasons for the massive extinction sweeping the globe involving amphibians such as the Panamanian Golden Frog along with chytrid fungus and habitat destruction.
Since many reptiles rely on amphibian prey, at least as young, how long will it be before their numbers are noticed to be in decline also?

You should also consider that many snakes are niche specialits. Ecological shifts of any sort (from habitat fragmentation to global climat change) tend to favor generalists. The Eastern cottonmouth, for example, may fare well (they eat darn near anying) whereas egg specialists will have difficulties because their prey has difficulties. Also bear in mind that "global warming" (better referred to as global climate change) will not warm the globe uniformly. Some models even predict an overall cooling in Europe if certain currents degrade.
