Polar Bears That Persist
A new subpopulation of Greenland polar bears offers insights into how this species might hang on as Arctic ice disappears......»»
How much carbon dioxide snow falls every winter on Mars?
Like Earth, Mars experiences climatic variations during the course of a year because of the tilted nature of its orbit (aka. seasonal change). Similarly, these variations in temperature result in interaction between the atmosphere and the polar ice c.....»»
Li Auto lowers delivery projections for 3Q21 on chip shortages
China's new energy car maker Li Auto is lowering sales projections by 500-1,500 units for the third quarter as semiconductor shortages persist......»»
Artificial Intelligence provides sharper images of lunar craters that contain water ice
The moon's polar regions are home to craters and other depressions that never receive sunlight. Today, a group of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany present the highest-resolution images to date cov.....»»
Predicting bear intrusions on settlements: A 15 year beech tree flower study
In recent years, black bears (Ursus thibetanus japonicus) encounter humans in rural and suburban areas of Japan leading to the deaths and injuries of people living near mountainous areas. Unfortunately, this means the suspected bears are exterminated.....»»
Melting of polar ice shifting Earth itself, not just sea levels
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geophysical Research Letters that, as glacial ice from.....»»
Image: Gloomy moonscape created for rover test
A sun barely peeking over a cratered horizon, casting long shadows across a rocky moonscape: ESA's Erasmus Innovation Center was transformed into an analog of the moon's polar regions, in a dress rehearsal for an international rover competition......»»
Could low-altitude reconnection power Jupiter"s polar aurorae?
Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions exceed those generate.....»»
Spring 2020 Arctic "ozone hole" likely caused by record-high north Pacific Ocean surface temperatures
Unlike the Antarctic ozone hole that develops annually during austral spring (September, October, and November), Arctic ozone levels usually stay well above the ozone hole threshold. The Arctic stratospheric vortex is typically too warm for polar str.....»»
How the canine teeth of carnivorous mammals evolved to make them super-killers
Carnivorous animals come in all shapes and sizes, from the 500-gram quoll to the 500-kilogram polar bear. This disparate group of mammals shares a common feature: canine teeth at the front of their jaws......»»
Hurricane Henri bears down on US east coast
Hurricane Henri was on course to make landfall on the US east coast Sunday, with millions in New England and New York's Long Island preparing for flash flooding, violent winds and power outages......»»
Under the northern lights: Mesospheric ozone layer depletion explained
The same phenomenon that causes aurorae—the magical curtains of green light often visible from the polar regions of the Earth—causes mesospheric ozone layer depletion. This depletion could have significance for global climate change and therefore.....»»
Census could be blessing or bane for Romania"s bears
Romania will soon conduct a census of its endangered brown bears using DNA for the first time, with tensions raised between villagers fearing further attacks and conservationists warning against looser hunting laws......»»
Effect of "eddy killing" in oceans is no longer a matter of guesswork
Ocean currents, propelled by kinetic energy from the wind, are the great moderators of our climate. By transferring heat from the equator to polar regions, they help make our planet habitable......»»
Increased snowfall will offset sea level rise from melting Antarctic ice sheet
A new study predicts that any sea level rise in the world's most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere. Using modern methods to calculate projected changes to sea levels, researcher.....»»
