Flowers use adjustable "paint by numbers" petal designs to attract pollinators, researchers discover
Flowers like hibiscus use an invisible blueprint established very early in petal formation that dictates the size of their bullseyes—a crucial pre-pattern that can significantly impact their ability to attract pollinating bees......»»
Climate change is accelerating extreme melting in Greenland with global impacts, says study
Climate change is accelerating the melting of ice in Greenland at an alarming rate, with serious implications not only for the Arctic, but also for the global climate, including Europe. According to a study led by researchers at the University of Bar.....»»
New findings on the extent of golden jackal expansion
The golden jackal (Canis aureus) has rapidly expanded its range across Europe by thousands of kilometers. It has recently moved into new environments, reaching as far as north of the Arctic Circle in Finland and Norway, and south to the Iberian Penin.....»»
How the west is foiling Russia"s attempts to use the Arctic in the Ukraine war
Things are not exactly going to plan for Moscow in the Arctic—an area that is a strategic military region for Russia and has significant economic potential that could help Russia in propping up its war economy. Yet, a combination of Ukrainian milit.....»»
International team decodes the genome of the Greenland shark

How plant coverage is affecting the Arctic carbon cycle
Researchers at Columbia University's Department of Earth and Environment Science have discovered new implications for the Arctic carbon cycle in the face of climate change. Their paper, published in Communications Biology, shows how differing plant c.....»»
Study of cloud movement in the Arctic could provide better understanding of climate change in the region
Special features of the Arctic climate, such as the strong reflection of the sun's rays off the light snow or the low position of the sun, amplify global warming in the Arctic. However, researchers are often faced with the challenge of modeling the u.....»»
Last voyage of an ocean drilling ship? Here"s why scientists don"t want to see the JOIDES Resolution mothballed
My favorite place in the world isn't a fixed location. It's the JOIDES Resolution, an internationally funded research ship that has spent its service life constantly on the move, from deep in the Antarctic to high in the Arctic......»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
NASA mission gets its first snapshot of polar heat emissions
NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experim.....»»
