Climate risk to inflexible penguins’ chicks

Crested and rockhopper penguins are threatened by climate change – but this time the penguins could be at risk because they cannot change their own ways. Evolution has left them with a rigid parenting strategy, probably well adapted for climate conditions so far. But as temperatures rise, conditions change and food supplies become precarious, the inflexible roles of male and female […]

More certainty on global warming

An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]

Antarctic scientists face breathalyzer tests due to alcohol-fueled fighting and ‘indecent exposure’

Breathalyzers could be used to curb alcohol abuse among scientists at US bases in Antarctica following “unpredictable behavior” caused by excess drinking, including fights and indecent exposure. Officials from the National Science Foundation told an audit of healthy and safety at the two US-run bases — McMurdo Station and the South Pole — that drinking has led to “unpredictable behavior […]

Climate report offers a grim forecast

What happened A United Nations panel of the world’s leading environmental scientists issued its most dire warnings on the dangers posed by climate change, saying global warming is already affecting every continent and threatens to devastate food supplies, cause mass extinctions of plants and animals, worsen droughts, and raise the risk of wars over resources. The longer society holds off […]

Tropical groundwater resources resilient to climate change

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

Flying Over Antarctica: Why Commercial Flights Avoid Antarctica

flying over Antarctica

Despite no legal prohibition on flying over Antarctica, the continent remains largely bypassed by regular commercial airlines. Experts point to a combination of environmental challenges, regulatory hurdles, and economic factors that make the South Pole a less-than-ideal route for modern aviation. Harsh Weather and Treacherous TerrainAntarctica is notorious for its extreme cold, unpredictable weather, and formidable terrain. Sudden storms, biting […]

What’s It Like to Work and Play in Antarctica’s Mac Town?

Nature films and science documentaries usually portray Antarctica to be nothing but the most cold, isolated, almost anti-social continent on earth — at least if you’re not a penguin — but life at McMurdo Station disproves that. The 2011-2012 Antarctic southern summer season is now alive and kicking (after numerous delays), and “Mac Town” (as the residents of McMurdo call […]

Giant boost for south polar waters

Giant boost for south polar waters

Massive icebergs more than 18km long give Giant boost for south polar waters by feeding vital nutrients into the Southern Ocean and helping to increase its carbon storage capacity. LONDON, January, 2016 – British scientists have identified the monsters that fertilize the Southern Ocean and help remove carbon dioxide from the atmosphere. Giant icebergs drifting northwards could be responsible for storing up […]
