A lab where scientists for weeks ntis time get an up close look at how Climate Change is altering life on the ocean floor. Buried alive the frantic tarch for survivors after an fvalanche hits a swiss ski resort. And former prisoners change peir lives by taking the stage ind writing their own second act. This is the Cbs Evening News with norah odonnell. Garrett good evening, yoeryone. Norah is off tonight. Im Major Garrett. We begin with postholiday headaches for millions of travelers, especially those on the road. According to a prediction from da. A. , today, the day after holidays, and for many, itsp aiving up to its billing. A powerful snowstorm shut down two of the nations busiest interstates today in, of all eftces, southern california. That left cars and trucks stranded for hours. Elsewhere, theres been heavyra. That messy mix is expected to push all the way to new england over the next few days. Tll get to the forecast in a moment, but first, jamie yuccas leads us off with tough
the stem outreach to kids. we are so excited about that. we ve reached over 2500 kids person to person over zoom calls with people in landlocked states, and kids out there that are thinking about careers in science, technology, engineering and math and we re talking to them about preserving, protecting and rejuvenating the marine environment. 60% to 70% of the oxygen comes from the world s oceans and we need to have those kids start taking better care than we did, unfortunately, better care for the ocean so it can give the life-sustaining oxygen that we absolutely need. plus, science is cool. maybe i m not quite so cool, but science can be very cool and you can do it in a fun environment like in the water. science is cool. 60% rem sleep is cool, too. i ll tell you that, dr. dituri. it is wonderful to have you from your undersea lab in key largo, florida. thank you for joining us. absolutely a pleasure. thank you for having me. thank you, sir.
abientists are studying the effects of climate change. reporter: about five miles flf of islamorada in the florida keys, some groundbreaking climate science work is being done on the ground that lies beneath ocean. there s only one wayge the undersea lab straight down, about 50 feet. the aquarius reef base, run by florida international university, has only recently been brought back into service after being badly damaged by hurricane irma two years ago. entry is via the aptly named wet porch. welcome to aquarius. quite an office we have here. reporter: an office with all the comforts of home, and jammed full of electronic equipment that can distort tv picture, but which allows scientists like jim fourquerean, to work down here, metimes for weeks at a time. a lot of attention is paid to make sure that oxygen concentrations are correct, and the co2 is at the right level.
