sensation. welcome in the sky. the world is in such a difficult position. the lake used to go half a mile around the corner mad and go, go kill that thing. good evening. welcome to the whole story. i m anderson cooper. tonight we take you on a journey around the world to meet people fighting against something that can be seen or touched, but his threatening our planet and the way we live more than a trillion tons of carbon gas has been released into our seas and skies over time. it comes from a lot of different sources, but the biggest is burning fossil fuels for electricity, heat and transportation. but tonight, cnn s chief climate correspondent, bill weir, has found some reasons to hope some unique ways innovators are trying to capture contain and reduce carbon emissions. they are climate warriors, and they just may show us how to unscrew a planet. attention humans of earth got good news and bad news. good news is that the combined sweat and brilliance of the 117 billion or
mist of seawater into the sky could create enough marine cloud brightening to turn down the heat just enough to refreeze the arctic for three months a year. to create a manageable future for humanity. we need deep and rapid emissions reduction. we need to remove excess greenhouse gasses and let s buy time by re freezing me out. take much of sir dave s work employs something called bio mimicry. the idea that nature is the best engineer so we should mimic earth systems at massive scales. and that is marty s philosophy. this is what s producing 50% of the degree coming up. we ll see how his ideas stack up against the little nation that leads the world in battling carbon godzilla. next stop. iceland.
kid, this place was absolutely alive with fishing boats going out to sea. coming to the fish exchange freighted with fish. i couldn t start working with everyone until, like a jump from boat to boat to boat because they re stacked up. that was the test. remember that really well? little marty odlum was that kid jumping boats. this one doc in portland s would move hundreds of thousands of cod day and he was certain he would grow up chasing macro on a rig. huge call the running tide. your dream was to have a boat. i just wanted to vote. i really just wanted a boat. what i wanted to do was go macro fishing, trying to figure out how i could do it. and i just couldn t make the math work on, you know financially just because the risks the climate risks were so high. there just aren t any mackerel. they swam north. they swam east and they re now probably have an iceland and they re actually swimming past
acidification is kind of the most terrifying thing i can possibly imagine to happen to the world. you know, 50% of our oxygen comes out of from phytoplankton. and where marty lives in maine. it is dying off at an alarming rate. like how is that? not on the front page of like every newspaper every day like breathing is awesome. i like doing it. and so to save the plankton that gives us breath. marty hopes his bowie is a breakthrough. a new science called artificial ocean alkaline ization. which would demand a lot of limestone. so the base case is like, okay, we take 2.5 mount fuji s of limestone. that s the volume 2.5 mount fuji s and dissolve that into the very top layer of the ocean. that s a lot of master move right? that s what it takes so that my kids can have can go fishing. like, give me a shovel. he would also love a crack at
iceland. while he was studying robotic engineering at dartmouth and earth systems at columbia. he realized a man made monster was destroying his beloved gulf of maine. warming it up at a rate now faster than 95% of the rest of the world. it s a godzilla. there s this thing out there, and it s like ruining everything that we love right. all the good stuff is getting ruined all the stuff that s free and fun. it s burning forest down. it s stealing our fish, devastating our crops. it s hurting our farmers. get mad and go, go kill that thing, right? and right there on a docking main. marty s metaphor is a lightbulb moment for me whole new way to think about a giant problem that began when people figured out how to move lots and lots of carbon that stuff of ancient life. from the slow cycle locked and rock and under oceans into the fast cycle. in
