An earthquake with a magnitude of 5.1 on the Richter scale hit the Greenland Sea on April 26, 2014, at 03:55:33 UTC at a depth of 10.00 km (6.21 mi). The epicenter of the earthquake is located right on the faultline that crosses the Arctic Ocean, at 73.479°N 7.974°E, some 567km (352mi) SSW of Longyearbyen, Svalbard.[ click on image to enlarge ]This follows four further recent earthquakes close to Svalbard or on the faultline north of Greenland, as indicated on above map. All these earthquakes...

Arctic sea ice area is in steep descent, as illustrated by the image below. Sea ice area was only smaller at this time of the year in 2007, for all years for which satellite data are available.[ click on image to enlarge ]Earlier this year, on March 9, 2014, Arctic sea ice area was at a record low for the time of the year. Since then, area did show some growth for a while, to the north of Scandinavia. This growth could be attributed largely to strong winds that made the sea ice spread with little...

Global Warming and FeedbacksIs there a mechanism that could make humanity go extinct in the not-too-distant future, i.e. within a handful of decades?Most people will be aware that emissions due to human activity are causing global warming, as illustrated by the arrow marked 1 in the image on the left. Global warming can cause changes to the land, to vegetation and to the weather. This can result in wildfires that can in turn cause emissions, thus closing the loop and forming a self-reinforcing...

An earthquake with a magnitude of 4.5 on the Richter scale hit the Arctic Ocean on April 13, 2014, at 02:12:19 UTC at a depth of 10.00 km (6.21 mi).The epicenter of the quake is located right on the faultline that crosses the Arctic Ocean, at 86.687°N 45.393°E, some 800 km north of Franz Josef Land.Earthquakes at this location are very worrying, as they can destabilize hydrates contained in the sediment under the seafloor of the Arctic Ocean. Furthermore, one earthquake can trigger further earthquakes,...

Levels of carbon dioxide (CO2) in the atmosphere are now firmly above the 400 parts per million (ppm) level, as illustrated by the graph below, from keelingcurve.ucsd.edu.As above graph shows, levels of CO2 go up and down with the seasons. Even higher levels are expected to be reached in May 2014. Importantly, 400 ppm is 143% its pre-industrial peak levels of 280 ppm.Levels of methane (CH4) in the atmosphere are rising even faster. According to IPCC AR5, methane levels were 1798 ppb in 2010 and...

The March 2014 Arctic sea ice volume, as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center, was the 2nd lowest on record at 21.818 km³. Only March 2011 had a lower volume, at 21.421 km³, as illustrated by the graph below, by Wipneus.Another way of depicting the continued fall of the sea ice volume is the Arctic Death Spiral below, by Andy Lee Robinson.This puts the sea ice in a very weak position. This month, the sea ice...

"If the permafrost melts entirely, there would be 5x the amount of carbon in the atmosphere than there is now" - Jeff ChantonJeff Chanton, the John Widmer Winchester Professor of Oceanography at Florida State.A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.The research is featured in the newest edition of the Proceedings of...

A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup. This discovery may help resolve the complex puzzle underlying why Arctic ice is disappearing more rapidly than expected.Lance Lesack, photo by Simon Fraser UniversityLesack is the lead author on Local spring warming drives earlier river-ice breakup in a large Arctic delta. Published recently in Geophysical...

Recent research results show that an atmospheric hole over the tropical West Pacific is reinforcing ozone depletion in the polar regions and could have a significant influence on the climate of the Earth.Potsdam, 3 April 2014. An international team of researchers headed by Potsdam scientist Dr. Markus Rex from the Alfred Wegener Institute has discovered a previously unknown atmospheric phenomenon over the South Seas. Over the tropical West Pacific there is a natural, invisible hole extending over...
