Sea level is rising for the first time in thousands of years. Oceanographer John Englander, author of "High Tide On Main Street" explains why it is unstoppable, regardless of efforts to be 'green' and sustainable. Using powerful images, he encourages us to embrace the new reality that the shoreline is moving, that we begin to adapt, while we also try to slow the warming. It is a positive message, "a glass half full, rather than half empty" -- though the glass will get higher each decade.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
