lot of global circulation of energy is driven by currents that, you know, warm water which the gulf stream, you know goes up the northeastern coast of the u.s. it's responsible for keeping the u.k. at a climate. the water, the whole system is driven as a conveyer belt system driven by the fact that cold water off of greenland is constantly sinking. that's driving this system of circulation. a concern in the new york's time recently ran a beautiful animation of the process. one concern is that as more and more fresh water melts off of greenland we interfere with this. it requires a dense cold salty water to keep it churning. some scientist would argue we are seeing because of the influx of fresh water off of greenland we are seeing a slowing of the current and some scientists say we don't have clear enough evidence of that yet. there is a fear that the circulation system could slow enough or shutdown you would wildly disrupt the climate pattern that has pertained throughout since the beginning of human civilization and that -- places like northern europe brings you back to global warming. t

looking at what effect this is having on the golf stream, the ocean current flowing from the gulf of europe, and researchers have had things shaped like necklaces to learn more about what is happening. joining us is the president and director of the oceanographic institute. thank you so much for being with us. can you just tell us why the gulfstream is so important in our weather system? peter: thank you very much for having me. the gulfstream is so important for the climate system, because at the latitude of florida, the ocean carries about one third of all of the energy that the earth accumulates at the equator, and so the ocean, when you think of climate and the ocean, they are interchangeable. the ocean is fundamentally, in fact, the largest component of the local climate system, so if the ocean is starting to change, this is a sign that there is really large-scale climate change underway. laura: and so, if it is the case, as you say, that melting ice from greenld is affecting the gulfstream, how serious the consequences be? peter: that is a great question. one of the things that

yeah the jet streams kind of doing this that trough, so that's the upper level winds. and so this grabbing air from the gulf of alaska and she just kind of sneaks in over, so that's that's generally how to get cold there and member of warm air underneath the jet stream. cooler air to the north of the jet stream. so when the judge if it doesn't matter where the jet streams located, you're always cooler to the north and warmer to the south. the air underneath. that s o. with that said, the cool air is here. temperatures tomorrow will be. little warmer than today. upper fifties low sixties like 61 62, that's you know, not 68 70 like we saw the other day, the forecast overnight lows and pretty chilly with that frost advisory. i'd call that cold and then a zoo get into san francisco tomorrow, a few clouds in the morning kind of cool and then the afternoon it doesn't get much warmer than 58 degrees in san francisco under mostly sunny skies here's tuesday. the whole day. here's wednesday, clouds increase wednesday night, and then here comes thursday. that's your rain thursday morning, right through thursday aftern

the jet stream is going well up into the gulf of alaska, losing all the moisture when it goes up that far to the north. so we are just getting a couple dried cold fronts and breezy conditions that will slow the warming trend, pushing us into the upper 60s in south ray today. mid to upper 60s along the peninsula with low to mid 60s on the coast side. mid 60s downtown in san francisco in a few 70s are possible on north bay valleys. mid to upper 60s on these bay shore and upper 60s to a few low 70s on the east bay valleys. tonight, how about 40s across the board with a few neighborhoods dropping into the 30s in the deepest inland valleys. we have a cold front on one of the cooler days with wendy offshore conditions tomorrow and wednesday i warming us above average. another cold front drops are temperature down on thursday looking at the offshore breezes and warmer temperatures saturday and sunday. that some spring warmth with the mid to upper 60s at the coast and mid to upper 70s for the rest of us. i know it's wednesday but the weekend is looking great . >> i marty planning in my head .
