But if sea level is capable of rising several feet per century, as Dr. O’Leary’s paper would seem to imply and as many other scientists believe, then babies being born now could live to see the early stages of a global calamity.

Turn up the heat on climate denial - Environmental Action

"A schoolchild can tell that the planet is getting warmer, and that human carbon pollution is the cause. Apparently, that simple truth is too difficult a concept for some members of Congress, like Iowa's Steve King. He recently told a Koch Brothers' group "if sea levels go up 4 or 6 inches, I don’t know if we’d know that.”*

In fact, unless we act now, climate change could cause sea level rise up to 69 FEET,more than enough to be apparent even from Iowa.** Unlike King, actual scientists know that if we do nothing, a 6-foot rise in sea level could put cities from Galveston, Texas, to  Miami, Fla. to Atlantic City, N.J., under water by 2030. ***"
