New York: Due to climate change, the world's oceans are getting warmer, rising higher, losing oxygen and becoming more acidic at an ever-faster pace and melting even more ice and snow, a grim international science assessment concludes.

But that's nothing compared to what United Nations-affiliated oceans and ice report says is coming if global warming doesn't slow down: three feet of sea rise by the end of the century, many fewer fish, weakening ocean currents, even less snow and ice, stronger and wetter hurricanes and nastier El Nino weather systems.
