Once-Shrinking Greenland Glacier Is Now Growing, NASA Study Shows (nbcnews.com)

kenh shares a report from NBC News: A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds. The Jakobshavn (YA-cob-shawv-en) glacier around 2012 was retreating about 1.8 miles (3 kilometers) and thinning nearly 130 feet (almost 40 meters) annually. But it started growing again at about the same rate in the past two years, according to a study in Monday's Nature Geoscience. Study authors and outside scientists think this is temporary.

A natural cyclical cooling of North Atlantic waters likely caused the glacier to reverse course, said study lead author Ala Khazendar, a NASA glaciologist on the Oceans Melting Greenland (OMG) project. Khazendar and colleagues say this coincides with a flip of the North Atlantic Oscillation -- a natural and temporary cooling and warming of parts of the ocean that is like a distant cousin to El Nino in the Pacific. The water in Disko Bay, where Jakobshavn hits the ocean, is about 3.6 degrees cooler than a few years ago, study authors said. While this is "good news" on a temporary basis, this is bad news on the long term because it tells scientists that ocean temperature is a bigger player in glacier retreats and advances than previously thought, said NASA climate scientist Josh Willis, a study co-author. Over the decades the water has been and will be warming from man-made climate change, he said, noting that about 90 percent of the heat trapped by greenhouse gases goes into the oceans.

    Christianity, Islam, what exactly is the difference? Oh, right, when Muslims bomb Christians we call it terrorism, when Christians bomb Muslims, we call it war on terrorism. In the end, one bullshit peddler offs another bullshit peddler, with sane people in the middle as collateral damage.

    No I don't, worship has nothing to do with it. You will not find the word worship used anywhere in science except in the study religion and even then only because worship is a central concept in religion. I don't think climate models are an omnipresent entity that only scientists can hear. So far no scientist has delivered to me a message from climate models that only they can hear that instructs me on how to live my life or else the almighty climate models will cast me into hell for an eternity of sadistic torture for refusing to 'believe'. That's how religion works.

    Yes, and climate alarmism is absolutely a religion cut from the same cloth. Man has sinned through industrialization, and the price to be paid is the destruction of our civilization. That's always about 10-15 years from now. Penance is made by deindustrialization and return to nature. Plus, of course, state control over all aspects of everybody's lives. Honest lefties will tell you that they also want the human population to decrease significantly. Of course, with entire countries disappearing under the rising oceans, that will happen, anyway according to their religion.

    That is a very standard religious model.

    Climate science, like all science, is a method of procedure that consists of systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses. Nothing in science is taken 'on faith' without any proof like in religion.

    Right, this is the standard fallback position.

    There actually is "climate science", and it mostly tells us that the earth is getting warmer.

    Climate alarmism, on the other hand, comes up with gems like this:

    While this is "good news" on a temporary basis, this is bad news on the long term...

    Everything is "bad news". Everything! It doesn't matter what happens, it'll be twisted to "I told you so!"

    This is what religion looks like.

    Science says "The glacier is growing again, I wonder what is making that happen since my hypothesis is that it should be shrinking."

    See the difference?
