"Paleoceanography, Rohling’s area of expertise, is the study of ancient oceans and ancient climates as they changed and developed together over geologic time. It involves analyzing data like layers of sediment taken from the seabed. Much alarming information can be learned this way, as Rohling demonstrates, about how today’s oceans are likely to respond to climate change--with greater acidification, sea-level rise, mass extinction and so forth. But because storms leave no geological record, the precise effect of global warming on hurricanes is harder to gauge. Still, Rohling is confident that the combination of rising sea levels and some form of increased storm intensity 'spells doom' for the world’s coastal regions. For surfers, rooting for hurricane swell may be increasingly difficult to rationalize."---James Ryerson, New York Times
