NASA: ARCTIC ICE GROWS AT FASTER PACE IN WINTER
New NASA research has found that increases in the rate at which Arctic ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover. Using climate models and observations of sea ice thickness from the European Space Agency’s CryoSat-2 satellite to explore sea ice growth variability across the Arctic, NASA scientists determined that arctic sea ice has been thickening at a faster rate during winter since the 1980s.
According to the Danish Meteorological Institute, Arctic sea ice volume is growing rapidly, normal and the highest in several years.
Christopher Booker from The Telegraph said three years ago: “the warmists ultimate scare scenario: those sea levels rising by as much as 20 feet, which, as Al Gore showed in his Oscar-winning film An Inconvenient Truth, would flood New York, Shanghai and many of the world’s most populous cities.
But, alas, it just isn’t happening. In recent years there has been more polar ice in the world than at any time since satellite records began in 1979. In the very year they had forecast that the Arctic would be ice free, its thickness increased by a third. Polar bear numbers are rising, not falling. Temperatures in Greenland have shown no increase for decades.”
Ron Cluz from Science Matters noted that this year “the Northwest Passage through Nunavut was closed this year due to excessive and thick multiyear ice blocking the way”.
Model simulations showed that in the 1980s, an extra 3.3 feet of ice would form over the winter compared to the average 6.6 feet thickness measured in October. That rate of growth has increased over the past three decades, and is expected to continue that trend for several more decades.
However NASA scientists say that is not enough to counter the dramatic long-term trend of sea ice melt caused by a warming world. The new data released nonetheless complicates the usual narrative of the Arctic’s big ice melt, raising questions about the sophisticated relationship between manmade and natural influences on the ice.
