Arctic Facing Increased Ice Melting due to High Temperature
The average temperature in the Arctic region in the recent times has led to melting of ice in the region at a much higher level. The level noticed in January this year, has not been recorded at this level in decades. The current heat wave has alarmed scientists tracking the region. Past records for temperature have been broken and the heat waves noticed in the recent months suggest much smaller ice cover in the region.
As per a recently published research paper in journal Nature, hot spells are noticed usually once or twice in each decade. However, researchers tracking ice and weather in the region have registered a third hot spell in less than 12 months. As the water isn’t freezing in many regions, scientists are worried about what would happen in the upcoming months.
The Arctic region plays an important role in climate of our planet. Scientists term Arctic region as a giant freezer pack that keeps out planet cool.
In a statement to the Washington Post, University of Toronto atmospheric physics expert Kent Moore that such Arctic heat waves might continue to be commonplace, as climate change continues to affect polar temperatures. However, the current warming is quite dramatic.
Mark Serreze, a senior research scientist with the Colorado-based Snow and Ice Data Center said, “We’re still trying to figure out what is happening here. The sea ice is so low there in part because it’s just been so darn warm in the Arctic this winter.”
A report published by CS Monitor informed, “Normally, this time of year is winter in the arctic, although you might not know it from this week’s balmy 40-degree temperatures in Svalbard, an island halfway between Norway and the North Pole. With weather typically in the single digits or teens, now is the time for sea ice to refreeze after the summer melt.”
Arizona State University physicist Steven Desch suggests a strange way of dealing with the situation. Desch said that building wind-powered pumps in the region can help in improving the ice cover in the region during winter months. If the ice cover is thick, it would have better chances of dealing with ice melt. Desch added, “Thicker ice would mean longer-lasting ice. In turn, that would mean the danger of all sea ice disappearing from the Arctic in summer would be reduced significantly.”
