Guest “geology lesson” by David Middleton Fire from the SkyResearchers find evidence of a cosmic impact that caused destruction of one of the world’s earliest human settlementsBy Sonia FernandezFriday, March 6, 2020 Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to…
Purple algae are making the western Greenland Ice Sheet melt faster, as the algae darken the ice surface and make it absorb more sunlight GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre The ERC (European Research Council) has awarded an €11 million Euro Synergy grant called DEEP PURPLE to Liane G. Benning at the German Research Centre for…
Public Release: 21-Jan-2019 Southwest part of the island could be major contributor to sea level rise Ohio State University COLUMBUS, Ohio – Greenland is melting faster than scientists previously thought–and will likely lead to faster sea level rise–thanks to the continued, accelerating warming of the Earth’s atmosphere, a new study has found. Scientists concerned about…
From EurekAlert! Public Release: 3-Jan-2019 Melting ice sheets release tons of methane into the atmosphere, study finds University of Bristol Melting ice sheet release tons of methane into the atmosphere, study finds The Greenland Ice Sheet emits tons of methane according to a new study, showing that subglacial biological activity impacts the atmosphere far more…
Guest AEUHHH???? by David Middleton A Terrifying Sea-Level Prediction Now Looks Far Less Likely But experts warn that our overall picture of sea-level rise looks far scarier today than it did even five years ago. ROBINSON MEYER JAN 4, 2019 One of the scariest scenarios for near-term, disastrous sea-level rise may be off the table…
Elevating this from a mention in my previous Newsworthy Items post. From ScienceNews Whether the impact is related to a period of cooling called the Younger Dryas is unknown By Carolyn Gramling 2:00pm, November 14, 2018 There’s something big lurking beneath Greenland’s ice. Using airborne ice-penetrating radar, scientists have discovered a 31-kilometer-wide crater — larger…
From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography under the ice is bowl shaped. =================================== Buried underneath compacted snow and ice in Greenland…
From the University of Cambridge The subglacial lakes are the first to be identified in Greenland The study, published in Geophysical Research Letters, discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly 8-10 km2, and at one point may have been up to three times larger than…
From the University of Buffalo Clues in the Arctic fossil record suggest that 3-5,000 years ago, the ice sheet was the smallest it has been in the past 10,000 years Summary: Ice sheets are like bulldozers. As they grow, they push rocks, boulders, clams, fossils and other debris into piles called moraines. By dating ancient…
NASA Begins Airborne Campaign to Map Greenland Ice Sheet Summer Melt For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. NASA’s C-130 research aircraft flew from the Wallops Flight Facility in Wallops…
