Welcome to Scientific American Science Talk posted on February 16, 2016. I Steve Merski. A small contingent of Scientific American

editors was at the annual meeting of the American Association for the Advancement of Science,

which ran from February 10th to February 15th in Washington, D.C. At the end of the day's sessions

on February 13th, I met up with Scientific Americans Mark Fischetti,

Dina Marin, and Seth Fletcher to hear about what they had heard about.

It's a huge meeting with sometimes 10 sessions going on at the same time.

Each of us could therefore attend only a small fraction of the briefings, so what follows is an admittedly idiosyncratic slice of the science presented at the AAAS conference.

Mark Fischetti, what have you come across while you've been here at the conference?

Two things have stood out to me. One is about sea level rise. You know, one of the cool things about AAA's conference or any really big science conferences,

you know, you have these general ideas and then when you get into the technical sessions,

you find out how much more interesting these stories are.

So sea level rise, right?

It's generally rising and everybody thinks about this is kind of like all the oceans are a bathtub, and so the water is just getting a little higher, right? It's generally rising and everybody thinks about this is kind of like all the oceans are a bathtub

and so the water is just getting a little higher, right? But it varies a lot around the world.

And why is that? And we have tide gauges and we have other gauges out in the ocean. We have satellite

measurements which show that, you know, this actual measured sea level rise is different quite a lot in
