This panel session featured Catherine Hart from Greensburg, Kansas. At 9:45 pm on May 4th, 2007 an EF5 tornado leveled the rural town of Greensburg, Kansas. Just days after the storm, the community came together and decided to rebuild sustainably, striving to become a model green town for the future (from Greensburg GreenTown wesite: http://greensburggreentown.org/history/).
Earth's climate depends on energy from the Sun. The Total Irradiance Monitor on NASA's Glory mission will continue measuring solar irradiance, which will contribute to the long-term climate record.

These are the seven principles that are essential for a good understanding of energy and its role in our lives and the life of our planet. This list was the work of several organizations including NSF, NASA, DOE and CLEAN.
To get a substantial portion of our electricity from wind means building hundreds of thousands of turbines. They’re affordable, so we could do that. But we usually don’t live in the windiest areas, so we’ll also need to build transmission lines—which is harder than building the wind farm itself. If the wind stops blowing when we need the power, we’ve got to replace it quickly with some other generation. Hopefully, challenges of siting, transmission, and backup generation won’t make this clean, affordable resource, unaffordable.
It's amazing how humans behave based on what they believe to be the state of the world. This TED Talk emphasizes how insights into human behavior are helping move people towards action on energy that helps to mitigate climate change.
Hurricane intensification can be caused by phenomenon called 'hot towers,' which form as air spirals inward towards the eye and is forced rapidly upwards, accelerating the movement of energy into high-altitude clouds.
Seven principles are essential for a good understanding of our ocean. This list was the work of several organizations, including NOAA, NSF, NASA, and NCAR.
The U.S. electric grid has been called the largest machine in the world. It’s also one of the oldest in continuous operation. Upgrading transmission in developed countries, and building more of it elsewhere, will be expensive but necessary to reduce power loss, inefficiencies and instability, and to accommodate renewables and distributed power production—a place where governments can help.
