dr. shini somara.arth is covered by ocean yet we know about the planets more than we do about the surface of the ocean. my question to you is, why should we care about what's down there? >> we are just starting to understand how the ocean and the deep ocean is going to be on providing global scale. >> and it seems like a harsh landscape down there and very, very far down. and there are a few technologies that allow us to go down there and you have a chance to go down there. >> 10,000 feet, just to get a chance to go down there it's tricky. i had a chance in a submarine called alvin. take a look. >> as we look for signs of life in space, these sients of the scientists of the deep are unlocking the secrets of below. >> what we're doing is astronauts and planetary scientists trying to study the life on another planet. >> oceans cover city% of the earth's surface with only a small parnlg part of it explored. we are traveling to costa rica to begin research of an underwater mountain the dorado outcrop. whil

dr. shini somara.a debate that somehow is still raging on - is the climate changing, is man to blame and is there anything we can do to stop the disaster. most agree the answers is yes. that's most scientists, not all of them. shini, crystal, lindsay, you each had a piece of the story. >> at the c.i.a. i was trained to analyse complex and sometimes contradictory data. climate change fits into that model as well. washington d.c. - politics are part of the equation. no matter what the science is, there's going to be contentious debate. >> i had a different experience. i was dealing with the scientists and citizens who are not debating if climate change is happening, but they are living it now. >> i think it's interesting that both sides of the debate claim to be on the side of science, and use studies as ammunition. we wanted to know who is right. things got interesting. >> as scientists we are trained to look at the data and go from there. that's what we try to keep in mind as we delve into the debate -

me drives me [ ♪ music ♪ ] >>> hey, guys, welcome back to techknow, i'm phil torres, joined by dr shini somarad lindsay moran. one of my favourite things about science is we are able to capture mother nature in a lab, take the phenomenon and see them at a university. >> yes, there's nothing more amazing than being able to recreate weather, that's what they were able to do at texas tech university. i got experience a tornado let's take a look. my first shoot for "techknow" was all about tornado technology, which was incredible. that's my area of expertise. it was so exciting flying to oklahoma and texas, where we got to see the facilities being used to research tornados. the passage of this is to learn about the innovation incorporated into building regulations to keep people safe during a tornado. at texas tech they establish the wind institute. and it's there that they have one of the largest tornado simulation laboratories. >> this is vor tech. >> it's great meeting the professor, who talked me through the design of the lab. we create tornado-like things that mimic the wind speed. >> he is m

dr. shini somara has an interview. >> high tide in miami beach has literally been inching up in the last 30 years. first a third of an inch, now accelerating 1.27 inches annually. by 2020, michael brown could disappear under six inches of sea rise. there is an enormous effort to save the city. to the casual observer, it looks like a nightmare but i can tell you as an engineer, the challenges are massive. >> what the city plans to do about it. >> miami city really shows you climate change. even on sunny days when we were there about there were gigantic puddles in the roads residents were telling us stories about how they lost their cars and property damaged because of rising sea levels. so it's a real problem happening right now. >> real problem. what are some of the possible solutions they're coming up with? >> well right now the solutions they have is to install pumps which literally take water from miami city and pump it back out. and the analogy is kind of like sitting in a canoe that is filled with holes and they are ladling is water out with a spoon. they've currently got eight pump
