![]() (Eddy Kennedy/CBC)ĭaraio has received funding from Natural Resources Canada to train engineers working with the provincial government to factor climate change projections into their designs. Joe Daraio, a hydrotechnical engineer at Memorial University, studies the hydrological impact of climate change, says the engineering profession is just starting to incorporate climate change in a more systematic and rigorous way. "We have a lot of coastal towns in Newfoundland and Labrador.… So how do we design a bridge crossing, a culvert to carry the largest possible flow?'' If we have a design life of 50 years, in 50 years the climate is going to be very different. Increasing sea levels and the coastal erosion they cause are of great concern to Joe Daraio, a hydrotechnical engineer at Memorial University who specializes in designing infrastructure to adapt to adverse events. Tarasov said warmer ocean temperatures below the ice sheet will cause even faster melting, and those rising sea levels will cause coastal erosion. "That ice will not form icebergs because they are not in the water." But when the ice shrinks to the point that it ends up on land, it can no longer fall into the sea to form icebergs. The Greenland ice sheet, measuring 1.7 million square kilometres, extends beyond land and over the sea. There's also going to be more melts in the Labrador Sea, so that might mean less and less icebergs making it to St. "By the end of the century, we're going to have less icebergs coming from Greenland. More melt could mean more icebergs in the near term, but fewer in the future, he said. Hundreds of icebergs appear off the coast of Newfoundland every spring, but scientists are concerned the pace of the melting Greenland glacier could mean that within this century, they may not make their annual migration. By boring down into the layers of ice, he said, scientists can tell that there was little change in the Greenland ice sheet between the mid-1900s to the turn of the 21st century. At that point, however, rapid melting began, he said. Tarasov's work is specifically on the Greenland ice sheet. Tarasov is the sole Canadian among a group of international scientists working on the Ice Sheet Model Intercomparison Project, the results of which will be presented to the International Panel on Climate Change later this year. That has prompted Memorial University glaciologist Lev Tarasov and his colleagues to study the relationship between glaciers and climate change. Proceedings of the National Academy of Sciences found the "deglaciation of Greenland" is resulting in ice melting four times faster than previously thought, raising concerns about the migration of icebergs to Newfoundland. ![]() The icebergs off Newfoundland "calve" - or break off - the western side of the Greenland glacier.Ī study published Jan. ![]() While 2019 has been considered a good year for glacial sightings, according to the North American Ice Patrol, the latest research indicates climate change could threaten the annual migration of the ice behemoths within this century. ![]() This is not an unusual occurrence, but the debris is normally lost when the iceberg flips over. So this one took part of Greenland with it. It lodged there after grinding through a valley in Greenland before it reached the ocean, and the debris stayed on top. This iceberg arrived and grounded off Bonavista with a lot of rocks and debris on the top.
