WSJ: World’s Ice Is Melting Faster Than Ever, Climate Scientists Say

#

Meteorologist Joe D'Aleo rebuttal: "Arctic warming and the melting of the arctic ice are not at all unprecedented (they happen predictably on multidecadal scales with a period of around 60 years) and are in fact entirely natural."  ... 

"Greenland data suggests the recent warming falls far short of earlier warming periods during the current interglacial and short of the warming early in the 20th century. The Antarctic has cooled and ice has increased in recent years although volcanism near the Antarctic peninsula leads to local water warmth and sea ice melting. Prior to the recent melting, the ice cover reached a long-term record high." ... 

"Also we should note that the prescribed melting reported in the Science Journal can’t be claimed a long time record as global ocean data prior to the satellite (1980) and Argo Buoy era (post 2004) is spotty at best. Even if the claims about water released were true, computations show global sea level would rise just 4 inches/century (agreeing with global data) and not the up to 24 feet promised decades ago."

The recent study confirms Antarctica has not warmed in the past 70 years and Antarctic ice cover is expanding rather than shrinking. Writing in the journal Nature, scientists at Columbia University and the University of Victoria, British Columbia report, “The Antarctic continent has not warmed in the last seven decades, despite a monotonic increase in the atmospheric concentration of greenhouse gases.”

The scientists also observe that over the past several decades, “Antarctic sea ice area has modestly expanded.”
