An international study lead by the Technical University of Denmark finds that the bedrock below the West Antarctic Ice Sheet is rising surprisingly fast which reveals an very fluid Earth Mantle. The unexpectedly fast rate of the rising earth may increase the stability of the ice sheet against catastrophic collapse due to ice loss.

A study by the Centre for Polar Observation and Modelling showed that Antarctica’s ice sheet is losing ground as it is eroded by warm ocean water circulating beneath its surface. The study was published in Nature Geoscience, and showed that the Southern Ocean melted 1,463 km2 of Antarctica’s underwater ice between 2010 and 2016, an area the size of London.

A range of less than one degree Fahrenheit, or half a degree Celsius, of climate warming over the next century, could be proven crucial for Arctic as it increases the probability of future ice-free summers in the Arctic, a research by the University of Colorado shows. The research also noted that if warming stays at 1.5 degrees Celsius, the possibility of ice-free summers would drop by 70%.

The four lowest seasonal maximums all happened during the last four years. The reduction of the Arctic sea ice cover has many effects, impacting climate and weather, the marine environment, and indigenous human communities. The reduced ice is also changing shipping routes, increasing coastal erosion and affecting ocean circulation.

According to the National Snow and Ice Data Center, data showed that ice is nearly 10% below average this January in the Arctic, an area larger than the states of California, Oregon and Washington combined. Carbon emissions are causing this change.

A study conducted by NASA, based on an innovative technique for crunching torrents of satellite data, provided a clear picture of changes in Antarctic ice flow into the ocean. The findings confirm increased ice losses from the West Antarctic Ice Sheet. The new work provides a baseline for measurement of Antarctic ice changes.

Arctic warming persisted in 2017, resulting in the second warmest air temperatures, above average ocean temperatures, loss of sea ice, and a range of human, ocean and ecosystem effects, according to a new report sponsored by the US NOAA.

An American geographer discussed about the opportunities which are emerging from the rapid change in Arctic for the Prince Rupert. He believes that Prince Rupert can take advantage of its location, considering that shipping passages through the Arctic are becoming viable options.

A one trillion tonne iceberg, one of the biggest ever recorded, has broken away from the Larsen C Ice Shelf, in Antarctica. The section broken is of 5,800 square km, which means the size of U.S. state of Delaware, and its volume is twice that of Lake Erie, one of the Great Lakes.
