notice how much-- notice how far down-- how far up the waterline is on the wood. that's because the whole weight of this is pushing down, yeah? well, this push down is hard when it's submerged?

they believe the waterline broke because of the gas explosion. they have two floors of rubble they're going through. it is very cold out here. the fire underneath was burning all night long. so there's a rescue and recovery effort, but the rescue effort has velgts hope to find any potential survivors. they are expecting to find more bodies. there are a number of people still missing. there's hope those people just happened to be out of town or for the around or not answering their phone, but as time goes on, this story presents, the hope for their safe return is certainly dwindling. de blasio toured the area just a few moments ago looking at the challenges, asking what their gap plan wasened and thanking them for their efforts. there are more than 100 people displaced as the people who lived in the former buildings. as well as others around them. windows were blown out. the blast could be felt to blocks. those more than 100 people are in shelters or staying with friends. long-term plans for them still unknown as investigators are trying to figure

the favorite slides are the waterline and as i see it's gotten above 7677 but it was flat 90 nor more precipitation it would go through below those numbers but we're having rain and expect more in the next two days and maybe we'll capture with the blue line to represents 2007. the snowpack not a lot of snow so we've emphasize to our customers while we are doing the 10 reduction now that will continue i'm convinced easily through this calendar year regardless of what happens because we can't get enough water and, of course, if perspiration didn't pickup we could go to a higher level of reduction. again, we have an inch and a half but based on the current forecast it mr. be above 18977 and another 6 inches by july will help to fill hetch hetchy reservoir. reduction in demand we're proposing for folks we've had a contracts for the lower aqueduct. the state relieve legislation was passed accelerating a lot of fund and people have been talking about how that can best be used. so we'll be looking at how to benefit our rate fairs in the potential of the relief drop. this is a skew mask we do

the black line, of course, is what hetch hetchy looked in our reservoirs and the green line is the waterline last year. hetch hetchy in the reservoir and the blue line goes back to 2007 and the orange line for you who are of my vintage remember the drought of 2007, you know, bricks in the toilet tanks that's the orange lion. the red line right there it's kind of overlays the erroneously line shows you how bad and the red line is the current year up to february. we're trending towards 1997 of the levels. we also know that the snow pack is a big portion of the hetch hetchy. emigrate black line is what they view from the average show pack into the watershed and the green line is again, the - is last year 2013 and the imply line shows you 23407 our last low water year and the red line is current. so let me give you one good slide here. with citywide the municipal water use has decreased so all the city departments are nearly on here. the water use has declined fwi percent since fiscal year 07 and 08 we're part of that but given the current drought there is more that needs to be done what are red

so they shut down one of the three waterlines. they're trying to find out if anything is wrong with the equipment. officials with the plant's operator tokyo electric power company plan to use the filtering system to reduce the amount of contaminated water stored at the plant. about 400 tons of groundwater each day flows into damaged reactor buildings and becomes contaminated, but the filtering system has been hit by a series of troubles. workers had just resumed operation of two lines on tuesday after leaks and a filter malfunction. >>> most people around the world know little about how north koreans live. they learn even less about those with physical challenges. one german man is helping north koreans with disabilities to reach out. >> reporter: these north korean youngsters have impaired sight. they locate the ball through the sound of a bell inside. until recently north korean children didn't have access to recreational equipment like this. german robert grund donated them to north korea. he's had impaired hearing since he was

mosher: i'm working on a pubc art project called the high waterline project, and for the project, i'm the 10-foot-above-sea-level line around the eire coast of brooklyn and lower manhattan, so it's almost 70 miles that i'm covering. and the point of the project is to get out into the communities that are gonna be affected by tha and give them a visual idea of what that means -- what the 10-foot-above-sea-level line means and also give them the tools to do something about that. so, along my way, i'm handing out action packets that give people tips on how to live more sustainably. a really important part of my project is the whole human element. i think a lot of times, they don't know, "okay, climate change -- first of all, what does that mean? and then, what do i do about it?" so, you have the media scaring you into thinking, climate change -- we just can't do anything about it. we should all panic and run away to higher ground. but there are things we can do about it. so, it's nice to be able to get out and talk to people. and i've found that no matter what background, noter where peo

these ships are the length of aircraft carriers, from the waterline they are 190 feet tall or nearly twice the height of the lincoln memorial. the ships can carry as many as 12,000 containers or translated into tvs, a million flat-screened tvs. thus the united states must be prepared to accept these larger vessels by 2015 when the panama expansion is complete. the port of savannah in savannah, georgia, is the second busiest u.s. container exporter, handling 13.2 millions of tons in exports in 2012 alone. it's the busiest port on the east coast. in order to accommodate the new larger ships at the port of savannah, the savannah river must be deepened from its current depth of 42 feet to 27 feet. georgia has been working on the harbor expansion project for well in excess of a dozen years. environmental studies have been completed, permits have been issued, state funding has been secured for 40% of the project. it has the support of every member of the georgia congressional delegation, and every single leader in our state. republican as well as democrat. this is a unifying, bipartisan pr

here's the waterline. when i take the metal out and throw it overboard, overboard, will this water level go up, will it go down or will it stay right there? the thing to think about is now the metal is made to float. when i take it and throw it overboard, then the metal sinks. any difference in the buoyant force on the metal either way? something to think about. question without giving away too much information. well, if the water was all the way to the top and there was an ice cube inside, there's ice cubes floating, if the ice cube melt, would the water overflow? that's a good point. how about that, gang? you've got a glass of water with an ice cube in it. the ice cube sticks up a little bit, yeah? when the ice cube melts, does the water level go higher, lower or stay the same? - higher. - it's higher. i'll be asking you that question at a different time.
