The Lake at the North Pole, How Bad Is It?

Climate Central reports:

The pictures are dramatic — a camera at the North Pole Environmental Observatory, sitting in the middle of what appears to be either a lake or open ocean, at the height of the summer sea ice melt season. Set against the backdrop of the precipitous decline in sea ice cover in recent decades due in large part to global warming, this would seem to be yet another alarming sign of Arctic climate change…

But before concluding that Arctic climate change has entered an even more ominous phase, it’s important to examine the context behind these images.

First, the cameras in question, which are attached to instruments that scientists have deposited on the sea ice at the start of each spring since 2002, may have “North Pole” in their name, but they are no longer located at the North Pole. In fact, as this map below shows, they have drifted well south of the North Pole, since they sit atop sea ice floes that move along with ocean currents. Currently, the waterlogged camera is near the prime meridian, at 85 degrees north latitude…

So far this summer, sea ice extent has tracked above that of 2012, with a slow rate of ice melt in June followed by much more rapid melting during the first three weeks of July after weather patterns became more favorable for melting, Serreze said.

“I would be extremely surprised if we were not” well below average come September, Serreze said, but the prospect of setting another record low “depends on the vagaries of the weather, and we just can’t predict that.”
