droughts are here now and will get worse in the coming decade. the amount of energy required to melt ice sheets (if that's what you're alluding to) is extremely huge and while it is certain they'll melt in a business as usual scenario (and possible if we stopped all emissions now...), it'll take hundreds if not thousands of years to get there. whereas extreme droughts are here today, now, as we speak.
