Historic Greenland was a lot hotter than beforehand thought
Though researchers have lengthy recognized that the final two interglacial durations skilled warming within the Arctic on account of modifications within the Earth’s orbit, a mixture of fly species preserved from these occasions in a uncommon lake sediment core reveals … Continue reading
Greenland glaciers’ diverse vulnerability to melting
Utilizing knowledge from NASA missions observing Earth, researchers have created new maps of the mattress topography beneath a rating of glaciers in southeast Greenland, thereby gaining a significantly better understanding of why some are present process fast retreat and others … Continue reading
Machine studying predicts new particulars of geothermal warmth flux beneath the Greenland Ice Sheet
A brand new article makes use of machine studying for the primary time to craft an improved mannequin for understanding geothermal warmth flux — warmth emanating from the Earth’s inside — under the Greenland Ice Sheet. Geology News — ScienceDaily
Inland thinning on the Greenland ice sheet controlled by outlet glacier geometry

The geology of East Greenland
Eighty percent of Greenland is covered by ice and, in places, this is up to 3.4km thick. So, Greenland might not immediately spring to mind as a place to go to observe rocks. However, it is a huge country and … Continue reading
Most of Greenland ice melted to bedrock in recent geologic past
Scientists drilled nearly two miles down through the summit of the Greenland ice sheet (white dot, left), to reach bedrock. Isotopes found in the rock indicate that this site and most of Greenland were nearly ice free (right) during the … Continue reading
Greenland ice is melting seven percent faster than previously thought
The same hotspot in Earth’s mantle that feeds Iceland’s active volcanoes has been affecting scientists’ calculations of ice loss in the Greenland ice sheet, causing them to underestimate the melting by about 20 gigatons (20 billion metric tons) per year. … Continue reading
Greenland rising as ice melts
A new study on the Greenland Ice Sheet provides valuable insight on climate change, using unique research methods to establish new estimates of ice loss for both modern and ancient times, says geologists. Geology News — ScienceDaily
Greenland ice is melting 7 percent faster than previously thought
The same hotspot in Earth’s mantle that feeds Iceland’s active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study, the hotspot softened … Continue reading
