The growth of Arctic sea ice this winter recorded the lowest maximum level on record, prompting fears of faster climate change than previously expected. Unusually warm temperatures were said to be responsible for the shrinkage.
2015 was by far the hottest year in modern times and raising new concerns about the accelerating pace of climate change. Not only was 2015 the warmest worldwide since 1880, it shattered the previous record held in 2014 by the widest margin ever observed, said the report by the National Oceanic and Atmospheric Administration.
In a new twist to the old song, it’s Santa Claus who had “better watch out” on Christmas Eve, as he shares the night sky with a huge asteroid that will make its closest pass to Earth at about the same time the jolly old fellow is making his annual deliveries.
The globally averaged temperature over land and ocean surfaces for March 2015 was the highest for the month since record keeping began in 1880. The year-to-date (January–March) globally averaged temperature was also record high, reports the US National Oceanographic and Atmospheric Administration, together with data from NASA.
The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers, an area roughly the size of North America.
NASA has lately spotted a gigantic iceberg in Antarctica, identified as B31 and together with UK's BAS (British Antarctic Survey), is busy tracking the monster island of ice, which has now escaped into open waters. Despite its sheer size and mass, --experts estimate that the giant iceberg is approximately 600 square kilometres in size--, monitoring is not going to be an easy task with the coming of the Antarctic winter and ensuing darkness.
Argentine space expert Jorge Coghlan said that the huge bang heard on Tuesday and that scared many people in central Santa Fe province was caused by a meteorite which disintegrated on entering the atmosphere and thus caused a major vibration. The incident was reported early mid morning.
When in December 2012, the NOAA National Geophysical Data Center and the NASA Earth Observatory released a new map of the Earth as it appears at night they found something fishy off the coast of Argentina but now the mystery has been solved. About 300 to 500 kilometers offshore, a city of light appeared in the middle of the South Atlantic Ocean. There are no human settlements there, nor fires or gas wells. But there are an awful lot of fishing boats.
The ozone hole that forms each year in the stratosphere over Antarctica was slightly smaller in 2013 than average in recent decades, according to NASA satellite data. The ozone hole is a seasonal phenomenon that starts to form during the Antarctic spring (August and September). The September-October 2013 average size of the hole was 8.1 million square miles (21 million square kilometers).
Hackers have hit back in retaliation for US cyber-spying on Brazil but mistook the US space agency NASA for the National Security Agency (NSA), a news website reported here Tuesday.
