Hi there. I'm Jeremy Werdell and I'm an ocean scientist at NASA's Goddard Space Flight
Center. I study how the ocean are changing as we see rising levels of carbon
dioxide in the atmosphere. Now the oceans are doing us a huge a favor
they soak up about half to a third of all the carbon dioxide
that man puts into our atmosphere, but they're very, very sensitive
to rising atmospheric temperatures. Fortunately we have a number of great tools
for measuring this greenhouse gas including the new Orbiting Carbon Observatory
2. It's really. really helping us better understand how this
greenhouse gas is warming the Earth.
