A single plant what if its thousands of flights. such a night data can also play a role in improving land and water management. in twenty fifteen knots and launched a new satellite. the satellite makes direct measurements of the soil moisture every few days. do you understand how much waters in the land surface that can really help you forecasting and monitoring droughts and floods were seeing here the red and yellow colors represent precipitation and the orange and blue colors are the changes i...

Few days. you understand how much waters in the land surface that can really help you forecasting and monitoring droughts and floods what were seeing here the red and yellow colors represent precipitation and the orange and blue colors are the changes and so when we share in the average blue colors represent whether areas and red colors represent drier areas so if you have a direct observation of the amount of more sure in the land surface and you can improve your understanding of the amount of ...

Didnt understand the intensity and how far these storms could move until we have satellite imagery. and nasa has over twenty earth observing satellites that are monitoring constantly different components of the energy in water and currents are using satellites were able to get a global picture of the land surface and different components of the land surface for example you can monitor the type and amount of vegetation in addition you can also tell how wet the yes will is by using microwaves so i...

Regions are sinking faster than others one example is the coastline of the u.s. state of louisiana. is the mississippi delta new orleans is located in this area in here and most of the land surface has been disappearing over the last thirty years and our projections are as this will disappear in the next ten twenty thirty years it will be gone and so. when this disappears water from a hurricane can more readily impact the city of new orleans so the cities on the delta are at risk all of them. i ...

Now the biologists say we are on the verge of the sixth. what are we doing to cause this and is it too late to stop? >> that is the key question. john sutter, whose voice you heard in that report. are we causing this? >> reporter: its clear that humans are causing this and a few factors. one of them is climate change. the way on we produce our energy by burning fossil fuels and other elephants and rhinos and giraffes and body parts sold on the black market and causing the species to crash. its h...

There by the time that happens. >> its a problem and the different water agencies will have to work together to figure that out. maybe we need to do something about this sooner than 20 or 25 years from now. >> in a perfect world, if we stop lowering ground water levels, subsidence will stop, but the land surface is not coming back up. >> stephanie said it. you have to know where to look. interesting story. we thank you for joining us this hour. im george howell at the cnn center. i will be back ...

The enormous search area. >> right. >> as long as its such a long area, its going to be real hard to find something. >> on that note, andrew, china is moving 21 of its satellites into position to search for the plane. talk to us about how satellite images are shared between their different agencies. would you say the more help the better from different nations? or does this further complicate the search? >> no. in this situation, the more data, the better. its always more welcome. i told you bef...
