Antarctic ice sheet is more vulnerable to carbon dioxide than expected

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

Antarctic Thaw Now Unstoppable

The continued melting of the West Antarctic ice sheet is progressing faster than expected, and the resulting rise in sea levels will have a global impact.The stark new findings point to a potential sea-level rise of up to 10 feet or more in the coming centuries. This increase in the global sea-level will threaten many major cities, including New York, […]

Antarctica’s Native Insect

Antarctica’s Native Insect - Antarctica Journal News

Antarctica’s native insect, the Antarctic Midge is a flightless insect that can survive nine months frozen at temps of at least negative 15 degrees Celsius.  It loses about 70% of its body fluids and can live for about a month without oxygen.  The midge survives because of its combination of rapid cold hardening and warm temperatures in its underground habitat.  […]

When the Red Planet was partly blue

Astronomers have found the strongest evidence yet that ancient Mars had a massive ocean for millions of years— an indication that the Red Planet once had everything necessary to support life. Shortly after Mars formed 4.5 billion years ago, NASA scientists say, the planet was wet, with enough water to cover the entire planet to a depth of about 450 […]

Galactic turmoil ahead

The Milky Way and its closest neighbor, the Andromeda galaxy, are on course for “ a head-on collision,” says astronomer Roeland van der Marel of the Space Telescope Science Institute. But no need for precautions because the crash won’t happen for another 4 billion years. Researchers have long known that Andromeda, currently some 2.5 million light-years away, is moving toward […]

Cleaning Up China’s Dirty Streets

“The Chinese need to learn that public spaces aren’t garbage dumps”, said Raymond Zhou. During a recent national holiday, visitors dropped a staggering 32 tons of litter in Tiananmen Square in just four days. Beijing’s army of street cleaners rushed in and quickly cleaned up the mess. But large areas of the country don’t have those resources, and by the […]
