According to researchers at Aalto University, by using suitable systems, more than 80% of heating energy for Finnish households could be produced using solar energy. As the price of heating energy obtained from solar heating systems needed to be competitive with the currently used heating alternatives, calculations made by researchers showed that renewable energy could be used to cover 53-81% of annual domestic heating energy consumption depending on the technical implementation method.
One of the best-known impacts of climate change is the loss of sea ice in the Arctic, but also in parts of the Antarctic: the poles are increasingly turning from white to blue. However, in the shallow seas near continental landmasses, the colour green also enters the picture: with the ocean ice-free for longer periods, the growing period for algal blooms also grows longer. These algae, in turn, provide food for seafloor-dwelling organisms, who use the carbon from their food to grow their bodies and shells.
Since 2004, tsunamis have received a much bigger attention after several of these big waves had hit coastal areas in Asia killing more than 200‘000 people. However, these waves are not bound to the tropical or subtropical areas. On Saturday, June 17th, waves had struck the western coast of Greenland, causing havoc and destruction and presumably leaving four people dead.
The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic. With the help of a climate model, researchers from the Alfred Wegener Institute have demonstrated how this process took place, allowing us for the first time to understand more accurately how Atlantic circulation as we know it today came about. The results of the study have now been published in the journal Nature Communications.
Despite the warming of the Arctic Ocean, vast areas are still covered with ice and hides an unknown world from scientific research. With the ice retreating, this world can be investigated and previously inaccessible parts of the Arctic open up and maybe reveal new life forms. A French expedition named “Under The Pole III” will try to fill this gap on a three-year expedition around the globe.
On May 24th 2017, 49 atmospheric and cloud researchers, sea-ice physicists, marine biologists and biogeochemists embarked on a joint expedition headed for Svalbard. On board the research vessel Polarstern from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) all of these disciplines are focused on just one question: How is the climate changing the Arctic? At the same time, the AWI research aircraft Polar 5 and Polar 6, launching from Longyearbyen (Svalbard), will engage in atmospheric measurement flights.
Narwhals are amongst the most mysterious marine mammals known. Although the species has been known for centuries and has been exploited by humans, only little is known about their ecology. Especially the tusk has spurred human fantasy. Now, Canadian fisheries researchers were able to show by video footage for the very first time that narwhal bulls use their tusks for fishing.
Five Arctic tourism organizations have joined forces to develop guidelines for tourists visiting Arctic communities. In addition to general advice on how to behave, the organizations presented a tool that allows communities create their own tailored guidelines.
The mass loss of the Greenlandic ice sheet accounts for more than a quarter of global sea level rise. Scientists anxiously observe the increasing impact of climate change on the entire ice sheet.
It is said that economics and ecology seldom go hand in hand. However, Norwegian entrepreneur Kjell Inge Røkke and his family present a perfect example to prove the general opinion wrong. Røkke has revealed plans for a brand new ice-strengthened research expedition vessel REV which will be built in cooperation with the World Wildlife Fund (WWF). According to the plans, the yet unnamed ship will be ready in 2020 to set sail.
