Jakobshavn glacier, West Greenland [image credit: Wikipedia]
Without jumping to hasty conclusions, this is an interesting development not predicted by the IPCC’s supposed experts. Natural ocean/climate oscillations are implicated. Against assumptions, rising carbon dioxide levels cannot explain these latest observations.
A new NASA study finds a major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, reports The GWPF.
The scientists were so shocked to find the change, Khazendar said: “At first we didn’t believe it.
“We had pretty much assumed that Jakobshavn would just keep going on as it had over the last 20 years.”
NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland.
The glacier is still adding to global sea level rise – it continues to lose more ice to the ocean than it gains from snow accumulation – but at a slower rate.
The researchers conclude that the slowdown of this glacier, known in the Greenlandic language as Sermeq Kujalleq, occurred because an ocean current that brings water to the glacier’s ocean face grew much cooler in 2016. Water temperatures in the vicinity of the glacier are now colder than they have been since the mid-1980s.
In a study published today in Nature Geoscience, Ala Khazendar of NASA’s Jet Propulsion Laboratory in Pasadena, California, and colleagues report the change in Jakobshavn’s behavior and trace the source of the cooler water to the North Atlantic Ocean more than 600 miles (966 kilometers) south of the glacier.
The research is based on data from NASA’s Oceans Melting Greenland (OMG) mission and other observations.
