A strong 6.3-magnitude earthquake has struck Papua New Guinea with no immediate tsunami warning or reports of damage. At least 127 people were killed and 2,000 are missing after mudslides swept away homes and destroyed roads in northwest China as the nation battled its worst flooding in a decade An ice island measuring 260 square kilometres broke off from one of Greenland’s two main glaciers, scientists say, the biggest such event in the Arctic in nearly 50 years. The new ice island, which broke off on Thursday, will enter a remote place called the Nares Strait, about 1,000 kilometres south of the North Pole between Greenland and Canada. Professor of ocean science and engineering at the University of Delaware, Andreas Muenchow, said he had expected an ice chunk to break off from the Petermann Glacier, one of the two largest remaining ones in Greenland, because it had been growing in size for seven or eight years. But he did not expect it to be so large. “The freshwater stored in this ice island could keep the Delaware or Hudson Rivers flowing for more than two years,” Professor Muenchow said. “It could also keep all US public tap water flowing for 120 days.” He said it was hard to judge whether the event occurred due to global warming because records on the sea water around the glacier have only been kept since 2003. The first week of July started with a high pressure system entering the Great Australian Bight extending a ridge up the east coast, bringing drier and cooler conditions to the Ranges Two organisations, CSIRO and the Australian Bureau of Meteorology have combined to present a current picture of Australia’s climate. A summary of their report shows that Australia will be hotter in coming decades. The National Oceanic and Atmospheric Administration (NOAA) and its British counterpart, the Met Office have released a report today that confirmed the existence of global warming. |
