The word glacial should be redefined to mean 'rapidly diminishing' rather than slow, researchers say, as the pace of change in the Arctic begins to outstrip their ability to understand what's happening Parts of the Arctic were an average of 11 degrees Celsius warmer than they were in the late 20th century as the region experienced “extreme record temperature anomalies”, the US National Oceanic and Atmospheric Administration (NOAA) has said. Scientists who produced the annual Arctic Report Card warned the situation was changing so quickly it was “outpacing our ability to understand and explain” what they were witnessing. They even...

The highest-ever wave of 19 metres (62.3ft) has been recorded in the North Atlantic. An automated buoy recorded the wave in the ocean between Iceland and the United Kingdom, the World Meteorological Organization said. It was created in the aftermath of a very strong cold front with 43.8 knot (50.4mph) winds on 4 February 2013. Image: WMO The WMO, which released the data, said the previous record was 18.275 metres (59.96ft) in December 2007. That wave was also in the North Atlantic. Image: The wave was captured by a buoy The buoy is part of the UK Met Office's network of...

When was the first expedition to the South Pole, who completed it and who else has made the journey? Over a century ago Roald Amundsen approached the southern-most place on Earth. With dozens of dogs and a handful of people, Amundsen finally reached the South Pole in December 1911. Today marks the 105th anniversary of that journey, which Google is celebrating with a Doodle. "In honour of that achievement, today's Doodle depicts the crew at the finish line, taking a moment to bask in the glory while the Antarctic wind whips outside their tent," said Google. Who was Roald Amundsen?...

Sperm whales are the biggest living things with teeth, and they seem to "talk" to each other. To decipher their messages, scientists are free-diving with them. A decade ago, Fabrice Schnöller was an engineer working on systems for tracking sharks. Then, in 2007, he went on a sailing trip to the island of Mauritius, where something happened that would change the course of his life. As his boat approached the coast, giant towers of steam began exploding out of the water. One by one the columns closed in, until they surrounded the whole boat. Curious as to the source of...

Scientists say they are concerned at the rate at which methane in the atmosphere is now rising. Image: Rice paddies are a significant source of methane After a period of relative stagnation in the 2000s, the concentration of the gas has surged. Methane (CH4) is a smaller component than carbon dioxide (CO2) but drives a more potent greenhouse effect. Researchers warn that efforts to tackle climate change will be undermined unless CH4 is also brought under tighter control. "CO2 is still the dominant target for mitigation, for good reason. But we run the risk if we lose sight of methane...
