Algal Mats May Be a Key to the Arctic Food Web
Melt ponds in sea ice have thriving algal communities with startlingly high levels of photosynthetic activity.
Groundwater Flow May Contribute to Submarine Permafrost Thaw
New, detailed surveys from the Beaufort Sea reveal a seafloor depression the size of a city block associated with permafrost thaw and likely influenced by the movement of groundwater below.
Arctic Sea Ice is Crucial for Forecasting Ural Blocking
By solving the nonlinear optimization problem, sea ice concentration in Greenland, Barents and Okhotsk Seas is found crucial for prediction of strong and long-lasting Ural blocking formation.
Arctic Ozone Loss Brings Warming to the Near Surface
New research confirms that ozone loss over the Arctic can lead to widespread warming near the Artic surface during late winter and early spring.
Los incendios forestales empeorarán, advierte informe de la ONU
Desde el ecuador hasta el Ártico, es probable que aumenten los incendios forestales y que el cambio climático los empeore, según un nuevo informe de las Naciones Unidas. La acción todavía es posible, dicen los autores.
Chronicling the Hottest, Coldest, Windiest, and Rainiest Weather
The World Meteorological Organization verifies and documents record-setting temperatures, winds, lightning, and more, offering snapshots of Earth’s extremes and hints about its changing climate.
Wildfires Will Worsen, Warns U.N. Report
From the equator to the Arctic, wildfires are likely to increase, and climate change can make them worse, according to a new United Nations report. Action is still possible, say the authors.
Lipids from Europa’s Ocean Could Be Detectable on the Surface
A super salty spring in the Canadian Arctic provides insights key to detecting life on a distant ocean world.
Can Aurora Enhance Radar Monitoring of Arctic Aviation?
Enhanced E-region ionization produced by the aurora can be used to reflect signals from over-the-horizon radars and thus enable those radars to better monitor aviation in Arctic regions.
