How To Lie, Without Lying

On September 15, 2007, at the time of the Arctic sea ice minimum, the MODIS on NASA's Terra satellite captured an unusually clear view of the open Northwest Passage. Although clouds appeared over some of the Arctic in mid-September, skies were clear enough to allow Terra’s MODIS sensor to observe much of the sea ice and open ocean throughout the Arctic.

This image is a mosaic of Terra observations of the Arctic, taken on September 15-16, 2007. Overlain onto the image are sea ice minima from 2007 (medium blue), the previous record from 2005 (light blue), and the long-term average from 1979-2000 (gray). The 2007 minimum, which correlates closely with the ice visible through clouds in this image, fell substantially below previous records. In 2007, all Arctic sea ice records were broken in August, more than a month before the end of melt season.

And so you might ask, why is the Arctic Sea Ice pack so small? Turns out, the very same NASA has the answer. NASA undertook a study, beginning after the then record lows of 2005 for Arctic sea ice pack and that study concluded on Oct 1, 2007. You probably heard little of it, because the study did not produce the required answer that the global warming hysteria crowd wanted.

NASA Examines Arctic Sea Ice Changes Leading to Record Low in 2007

The scientists observed less perennial ice cover in March 2007 than ever before, with the thick ice confined to the Arctic Ocean north of Canada. Consequently, the Arctic Ocean was dominated by thinner seasonal ice that melts faster. This ice is more easily compressed and responds more quickly to being pushed out of the Arctic by winds. Those thinner seasonal ice conditions facilitated the ice loss, leading to this year's record low amount of total Arctic sea ice.

Nghiem said the rapid decline in winter perennial ice the past two years was caused by unusual winds. "Unusual atmospheric conditions set up wind patterns that compressed the sea ice, loaded it into the Transpolar Drift Stream and then sped its flow out of the Arctic," he said. When that sea ice reached lower latitudes, it rapidly melted in the warmer waters.

"The winds causing this trend in ice reduction were set up by an unusual pattern of atmospheric pressure that began at the beginning of this century," Nghiem said.

The Arctic Ocean's shift from perennial to seasonal ice is preconditioning the sea ice cover there for more efficient melting and further ice reductions each summer. The shift to seasonal ice decreases the reflectivity of Earth's surface and allows more solar energy to be absorbed in the ice-ocean system.

The perennial sea ice pattern change was deduced by using the buoy computing model infused with 50 years of data from drifting buoys and measurement camps to track sea ice movement around the Arctic Ocean. From the 1970s through the 1990s, perennial ice declined by about 500,000 square kilometers (193,000 square miles) each decade. Since 2000, that amount of decline has nearly tripled.

Lies by omission, the secret weapon of the leftists mainstream media. Winds caused the ice pack to shrink, winds that have been observed before.
