Climate Disruption, sounds like some nasty laser weapon off Mars Attacks - but actually is the new 'marketing phrase' for Climate Change / Global Warming. See here for a discussion on it.
Basically, it looks like the old phrase is just not 'general' enough; i.e. they have been finding hard to get the message through when people keep asking awkward questions about the underlying science.
Climate Disruption is a much more general and 'fluffy' term that allows anything out of the ordinary that happens in the climate (and weather) to be attributed to man made global warming; without really having to prove it, as the term in itself is so vague and yet sounds so nasty - a true marketing masterpiece..
I really do hope the public work out the trick thats been played here and consigns this new language to the mental bin it so deserves.
