Global Warming to Alter the Planet’s Shape

Climate change affect not just temperature, but it also alter the Earth’s shape according to the Scientists from the University of British Colombia.

One of the most rapidly warming regions of the world, the Canadian Acrtic will feel these effects acutely. More than 4 degree celsius of warming over the last 50 years, the glaciers will be seen flowing up to 100 times faster if the climate shifts above zero degree celcius.

Michele Koppes, assistant professor in the Department of Geography at the University of British Columbia, in a five-year study compared glaciers in Patagonia and in the Antarctic Peninsula.

Scientists found out that the glaciers in the warmer Patagonia moved faster and caused more erosion than those in Antarctics as warmer temperatures and melting ice helped lubricate the bed of the glaciers.

Although this broad region has a relatively uniform tectonic and geologic history, the thermal regimes of its glaciers range from temperate to polar.

“We found that glaciers erode 100 to 1,000 times faster in Patagonia than they do in Antarctica,” said Koppes.

“Antarctica is warming up, and as it moves to temperatures above 0 degrees Celsius, the glaciers are all going to start moving faster. We are already seeing that the ice sheets are starting to move faster and should become more erosive, digging deeper valleys and shedding more sediment into the oceans.”

Researchers added, “Glacial erosion rates are expected to increase with decreasing latitude, owing to the climatic control on basal temperature and the production of meltwater, which promotes glacial sliding, erosion and sediment transfer.”

India keen on balanaced climate change pact

Prior to the 2015 United Nations Climate Change meeting, India has started to collaborate with several countries as it profoundly looks forward to guarantee a fair and equalized contract at the summit, scheduled to be held in December.
