The loss of a nearly 4.5-square-kilometer expanse of ice in a single day from Greenland's Jakobshavn Isbrae glacier is a warning sign of increasing water temperatures, according to researchers at the US National Aeronautic and Space Administration (NASA).
The detachment of the huge piece of ice caused the ocean to effectively move 1.6 kilometers further inland, a point more interior than what has ever been previously observed. The Jakobshavn Isbrae glacier, which has seen drastic ice losses since 2001, is believed to be the largest factor in northern hemispheric sea level rise.
Thomas Wagner, cryospheric program scientist at NASA, noted that this recent event occurred just after an Arctic winter season in which no ice had formed in the surrounding waters. He commented, “While the exact relationship between these events is being determined, it lends credence to the theory that warming of the oceans is responsible for the ice loss observed throughout Greenland and Antarctica.”
NASA scientists previously observed that west Greenland's glaciers are melting 100 times faster at points beneath the ocean than on their above-ground surfaces, saying that the likely explanation for this discrepancy is warming ocean water.
Dr. Wagner and other National Aeronautic and Space Administration experts, we thank you for these observations that further reveal the predicament of our fragile biosphere.
May we all act now in effective ways to cool and re-stabilize our shared planetary home.
