In this article on global warming, the writer makes the claim:
"The number of people affected by extreme natural disasters, meanwhile, has surged by almost 70 percent, from 174 million a year between 1985 to 1994, to 254 million people a year between 1995 to 2004, Oxfam said."
An increase of 70% from a base of 174 million should be 295.8 million. The writer did 174/254 to come up 70% (after a round off). It's actually a 42.6% increase, which is also pretty scary, but they are overstating the problem. However, in a few more years, we're prolly about that screwed.
