. >> hey guys this episode gets personal, i'm here with doctor crystal dilworth and marita davison, and my epi pen. and i have it for a very important reason which is i'm allergic to peanuts and some other nuts too, but if i get too close to peanuts, one of you would have to grab this, take off the lid, and jab me in the thigh. >> i'm lucky, i don't have any allergies, but phil i know this is something you have to really organize your life around. i mean even here at this coffee shop you have to ask if anything here is cooked with peanuts or peanut oil before you can order off the menu. >> kind of a pain when it comes to ordering in places like this. >> but you know what's surprising and i would say really alarming is that the number of people like you, phil, with food allergies has skyrocketed in the last few decades, and we went to find out why we're seeing a rise in food allergies and if we might find a cure. >> it was terrifying. his face basically swelled up like twice the normal size. >> when you've held your daughter in your arms almost dying because of something as basic as milk

crystal dilworth and marita davison. and, it sounds surreal to say but it's possible that within our lifetimes, all the coral reefs will be gone. >> scientists are saying that without some drastic changes, 100% of our coral reefs are facing degradation by 2050 which is only 30 years away. >> it could be an ecological disaster. >> and the problem is they are being attacked on all fronts, right now they're going through this coral bleaching event where all the corals are basically starving. >> yeah, and this bleaching event is affecting, right now, 40% of coral reefs worldwide, hawaii has been particularly hard hit, i got to go there to check it out and see if there's anything we can do to save the coral reefs. >> keno'ahe bay on the eastern side of oahu, hawaii. famous for clear blue seas and coral, rich in color and marine life. but now there's trouble in these waters. the coral is dying. in fact, reefs around the world are in trouble. we're here to find out why. >> some reefs have recovered much more quickly than others

crystal dilworth and marita davison, and today we're talking el nino and this is something we've seen here on the west coast in the us, but it definitely extends far beyond that and marita you've actually experienced it. >> i've experienced a few el nino events when i was growing up in bolivia so it certainly has global impacts but what it is is an interaction between the ocean and the atmosphere that happens in the tropical pacific ocean. >> for some this interaction seems like this mysterious force, but this is techknow so of course we want to know what an el nino is, the weird things it's doing, and how researchers are studying it. >> severe fires and drought leading to food shortages in 11 south pacific countries. mega flooding in central america forcing thousands to evacuate their homes. and sea life found hundreds of miles from their natural habitats. all this due to a powerful weather system known as el nino. this year's el nino is already breaking records for the wettest start in the pacific northwest, flooding homes and causing treacherous landslides. >> they come in all size
