What is the hydrosphere and why is it important?

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic. 

Every day, scientists at NASA work on creating better hurricanes on a computer screen. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, a team of scientists spends its days incorporating millions of atmospheric observations. Sophisticated graphic tools and lines of computer code to create computer models simulating the weather and climate conditions responsible for hurricanes.
