Sea levels have risen almost a foot in the past century, partly because of ice melt and thermal expansion (warmer water has more volume), and partly because of naturally occurring land subsidence of the Northeast. In the same period, area temperatures have risen nearly 2 degrees F. About two-thirds of that increase occurred in the past 30 years and sea-level rise has accelerated in the past decade. "The core body of knowledge has solidified" on climate change, says Cynthia Rosenzweig, the lead GISS scientist on the climate-change task force. "We're moving into a solution phase."
