Hansen still argues 5m 21st C sea level rise possible
“…Are we on a slippery slope now? Can human-made global warming cause ice sheet melting measured in meters of sea level rise, not centimeters, and can this occur in centuries, not millennia? Can the very inertia of the ice sheets, which protects us from rapid sea level change now, become our bete noire as portions of the ice sheet begin to accelerate, making it practically impossible to avoid disaster for coastal regions?”
