Satellite snafu masked true sea-level rise 24.7.2017 Deccan Herald - Supplements
The numbers didn't add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea level rise was holding steady — or even declining. Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year. "The rate of sea level rise is increasing, and that increase is basically what we expected," says Steven Nerem, a remote-sensing expert at the University of Colorado Boulder, USA who is leading the reanalysis. Steven presented the as-yet-unpublished analysis recently at a conference sponsored by the World Climate Research Programme and the International Oceanographic Commission, among others. Steven's team calculated that the rate of sea level rise increased from ...

The ever-shrinking Antarctic ice shelf 13.7.2017 Deccan Herald - Analysis
A chunk of floating ice that broke away from the Antarctic Peninsula this week — as confirmed by the National Aeronautics and Space Administration (Nasa) of the USA — producing one of the largest icebergs ever recorded and providing a glimpse of how the Antarctic ice sheet might ultimately start to fall apart. A crack more than 120 miles long, had developed over several years in a floating ice shelf called Larsen C. Scientists carefully tracked it in recent months, and images shot by a Nasa satellite on Wednesday morning showed that a 2,200-square mile chunk had finally broken loose. There is no scientific consensus over whether global warming is to blame. But the event fundamentally changes the landscape of the Antarctic Peninsula, according to Project Midas, a research team from Swansea University and Aberystwyth University in Wales that had been monitoring the rift since 2014. "The remaining shelf will be at its smallest ever known size," said Adrian Luckman, a lead researcher for Project ...

The massive ice cube, larger than the US state of Delaware, has a volume twice that of Lake Erie, one of the Great Lakes. It is about 350 metres (1,100 feet) thick. The iceberg weighs more than a trillion tonnes and it will likely be named A68.
