Comments Off on Previously stable zones of Antarctica are now falling victim to climate change

Unlike its counterpart, West Antarctica, which has long been decimated by melting ice caps, East Antarctica used to be a safe zone – something scientists could depend on as a constant while they solved the more pressing destruction in the western part of the continent. Unfortunately, this is no longer the case. According to  research unveiled last week in the journal  Geophysical Research Letters , despite the higher elevation and colder temperatures found in the eastern portion of the Antarctic continent, warm ocean currents and rising global temperatures are now destabilizing two of its glaciers. The research has chronicled the lives of two glaciers in the coldest region on Earth for the past 15 years. These glaciers shield the Eastern zone’s land ice, descending from the ice directly toward the sea. This creates a naturally formed dam that, if disturbed, would affect the ice that covers the rest of the region by subjecting it to the warming ocean waters. The melting of these two massive glaciers alone would raise sea levels more than 16 feet (five meters), undoubtedly compromising the rest of the territory. In an interview with Earther , Yara Mohajerani, lead expert in the study and PhD candidate at the University of California, explained, “The East Antarctic ice sheet contains much more ice and sea level potential than any other ice sheet by far, making it of crucial global significance.” Past research has shown the disappearance of similar glaciers in the East Antarctic region when carbon dioxide levels in the atmosphere have reached levels comparable to those found today as a result of human activities. Related: Scientists uncover giant canyons under the ice in Antarctica Scientists believe that, due to the circulation of warm ocean water under the two glaciers, they’ve been losing mass for quite some time. To help quantify the losses, NASA provided the researchers with its Gravity Recovery and Climate Experiment (GRACE) satellite, which measures small changes in gravity. GRACE collected data from 2002 to 2017, and the new study reveals that the glaciers are losing 18.5 gigatons of ice each year, or the equivalent of 7.4 million Olympic-sized swimming pools. While this is minuscule in comparison to losses in the rest of Antarctica, the location of these glaciers makes their survival central to the discussion of East Antarctica’s stability and, therefore, the state of the continent as a whole. + Geophysical Research Letters Via Earther

1.5 billion birds disappear from North Americas skies

Comments Off on 1.5 billion birds disappear from North Americas skies

A startling survey of North American skies reveals there are 1.5 billion less birds flying about than there were decades ago. Some species’ populations have recently become threatened , while others are projected to be nearly decimated within the next 40 years. An array of factors, mostly human-induced, are responsible for the alarming drop. “It’s the death of a thousand cuts,” stated the survey’s co-author Judith Kennedy, of Environment Canada. “We’re really getting down to the dregs of some of these populations.” Numerous government, environmental, and university-based agencies combined to conduct the most comprehensive, up-to-date Partners in Flight survey, which follows trends in continental bird populations . Related: 9 things you can do to help wild birds this summer 86 species of birds were classified as threatened by habitat loss, climate change , and plummeting population sizes. These include the Canada warbler and evening grosbeak, whose numbers have dropped 92 percent since 1970. Even the beloved snowy owl has experienced a 64 percent dip. Logging of forests, pesticides in grasslands, and an overabundance of cats – who kill an estimated 2 billion birds per year – all contribute to the downfall of the continent’s birds. Birds help human populations by gobbling up pesky insects and pollinating plants. Kennedy stresses the importance of making changes in our behaviors that affect native bird populations, stating, “It’s too late for us to worry when we’re down to the last few hundred.” Via The Star Images via Flickr , Wikipedia

World’s most massive canyon may be hidden beneath Antarctic ice

Comments Off on World’s most massive canyon may be hidden beneath Antarctic ice

Researchers from Durham University have discovered what appears to be a massive canyon system beneath Antarctica’s ice. Using satellite data, geologists have mapped out a system over 1,000 kilometers long (621 miles), with sections that run up to 1 kilometer deep (3,280 feet) in the Princess Elizabeth Land region on the eastern side of the continent. For comparison, the Grand Canyon is only about 446 kilometers (277 miles) long. Read the rest of World’s most massive canyon may be hidden beneath Antarctic ice

Comments Off on Italy is suffering from an overabundance of architects

You’ve heard of too many cooks in the kitchen, but what happens when there are too many architects? A new report from the Architects’ Council of Europe shows that 27 percent of all the architects on the continent are licensed in Italy—that amounts to 153,000 architects, which is 50,000 more than there are in the U.S. This alarmingly high concentration of architects means stiff competition for a limited number of jobs.

South Africa’s New 96MW PV Plant is the Continent’s Largest Solar Power Facility

Comments Off on South Africa’s New 96MW PV Plant is the Continent’s Largest Solar Power Facility

South Africa is a historically coal-hungry nation, producing around 225 million tonnes of the stuff each year. But just two years ago, government leaders pledged to invest an incredible $5.4 billion in renewable energy , and the products of that investment are taking shape. The Jasper PV Project in Kimberly, South Africa, became fully operational in October, and produces enough power to serve an impressive 80,000 homes. It’s now the largest solar power plant in Africa. The better news? It’s soon to be eclipsed by an even bigger facility nearby.
