Listening to a program on the radio this evening brought home (finally - duh!) what is wrong with the expression "Global warming". It'd been at the back of my mind all along, but it finally crystallized - putting heat into a system does NOT necessarily mean that the temperature is going to increase.
Consider ye a bucket of ice, at just below freezing point. Add heat - what happens? Yes! the ice melts. Does it get significantly "warmer"? No! The energy input is changing the phase - anyone who's not familiar with this should check out "latent heat". Then look at Arctic ice cover.
Consider other possible things this additional energy could do - make bigger storms, maybe? They take quite a lot of energy - n'est pas?
Try "climate change".
