This is CBS, I'm the World, I'm John Baxter with Professor Beth Tellman, University of

Arizona Geography Department, also the Chief Science Officer and Co-Founder of Cloud

District, publishing a Nature magazine, the premier peer-reviewed magazine for science

in Europe, matching science here about a database compiled using satellites, NASA satellites

to point to where the flooding has been the early years of the 21st century, where the

people are, the movement of people, growth of people in the flood lanes, and what all

that adds up to is, for example, I learn in the summary of the article.

This is a very useful item for financial speculation about municipal bonds, what is and

what is not desirable for insurance, for areas that have experienced floods or might experience

floods again.

A hundred-year flood means you have 1% every year, and as we note recently, there are

a whole lot of 1%ers coming in, so Professor, if I go to the summary correctly, Asia dominates

the story, 398 of the 913, 52 in China, 85 in India, the ones in China seem especially

damaging.

Did you pick that up with your satellite images?

Yes, there are a lot of floods that were mapping in Asia, generally, southern Asian,

Southeast Asia specifically, and some of the largest growth we've seen in people building

and moving into flood plains has been in these regions.

So you can see, for example, if you are in the paper on figure four, a lot of these countries

on figure four A that you'll see lighting up in orange and red, those are the countries

where we've seen a lot of growth in flood plains in about the past 20 years.

But what's even more concerning is figure four B, these are climate change projections
