In the last 60 years, natural disasters, driven by climate change, are punishing coastlines at a far greater rate than inland disasters (see graph).

Not to mention the fact that 40% of the world’s population lives in, commutes through, works around, and is otherwise part of this impact zone.

Last week, we splashed down at Woods Hole Oceanographic Institution (WHOI) to host another fun Ocean MBA, which featured over 30 WHOI researchers, engineers, staff, and students, along with scientists from Bigelow Laboratory for Ocean Sciences. Dozens of mentors and instructors joined us to share their knowledge and learn more about the WHOI teams’ work. The feedback from all teams was overwhelmingly positive, emphasizing the entrepreneurial insights gained and the invaluable support from our mentors.
