What you fail to note is that climate scientists have also warned for more than 20 yrs  that rainfall all over the world would be much heavier and in much greater amounts due to the warming of the waters that causes increased  evaporation that falls as very heavy & prodigious rain. When we experience a 100 yr event (Katrina), a 500 yr event (Sandy) and an 800 yr event(harvey) in the space of 12 yrs perhaps you should take notice. BTW, Pakistan & Bangladesh is now experiencing such heavy rains & flooding that more than 1200 people have died and 41 million have been adversely affected. Time to take off your political hat and switch to your logical hat, if you have one.
