“Scientists know of only three prior occasions during the past 800 years when there has been melting at the very top of the ice cap, which is kept chilled by the large volume of ice beneath. But… it is now the second time this decade it has happened.

The last time we saw melting at the summit, in 2012, we thought it was the extreme of the extremes, and wouldn’t happen again so quickly,” says Konrad Steffen, a professor of climate and cryosphere at ETH Zurich, who operates a network of 18 monitoring stations across the ice sheet. “But now we are facing more of these extremes.”

“Prof Steffen’s data shows that between July 30 and August 2 a heatwave in Greenland produced several record highs across the ice sheet, including at East Grip, the second highest monitoring station. “If you start melting at the top of the ice sheet, we are going to lose [the] Greenland ice sheet long term,” he adds.

“The immediate trigger for the heatwave was a shift in atmospheric currents high above the earth’s surface: the North Atlantic Jet Stream, a fast current of wind that blows from west to east, had formed a buckle that was trapping warm air over Greenland. The same pattern had caused a record-setting heatwave in Europe a few days earlier, before shifting over to sit on top of the Greenland ice sheet.”

“Mass losses from Greenland this past week were already approaching levels not expected until 2070 based on the best available models.

“It is still too early to tell if the ice losses for the summer will exceed the losses in 2012, but it is clear that the Greenland ice sheet is rapidly responding to climate change, even faster than many scientists expected. “

“In the continually warming Arctic, sea ice has completely melted around the Alaskan coast before, notably during 2017’s melt season, but never this early.

“”It’s cleared earlier than it has in any other year,” said Thoman…

“”I’m losing the ability to communicate the magnitude [of change],” Jeremy Mathis, a longtime Arctic researcher and current board director at the National Academies of Sciences, told Mashable…”

“The worst of the fires are burning in Siberia, where almost 12,000 square miles are ablaze, sending thick smoke across roughly 800 cities in northeastern Russia, including Novosibirsk, Krasnoyarsk and Chita.

“Upper level winds have carried some of that smoke across the Pacific Ocean and into North America, says NASA, covering parts of Alaska and Canada in addition to our neck of the woods.”

“The wildfires which hit northern California have become “too extreme” even for the black-backed woodpecker which thrives in burned out forests, according to scientists.

“The bird, which lives in the mountainous areas of the western U.S., favors recently burned trees where it can feast on the larvae of wood-boring beetles that inhabit dead wood.”

“Chennai is not the only Indian city experiencing the possibility of a waterless future. A total of 21 major cities are poised to run out of groundwater next year, the National Institution for Transforming India (NITI) Aayog, a government think tank, warned in a 2018 report. “In view of limitations on availability of water resources and rising demand for water, sustainable management of water resources has acquired critical importance,” the report said.”

“The Kariba dam that straddles Zambia and Zimbabwe, the world’s biggest man-made reservoir, is emptying fast, sparking fears the countries may have to cut hydropower production there completely.

“For the two southern African nations already suffering daily blackouts and growing economic pressures… a total shutdown at Kariba would be crippling. Zambia gets about a third of its supply from the dam, Zimbabwe almost half.”
