Researchers from the Digital Geography at the University of Helsinki have been studying whether social media data could be used to understand visitor’s activities in national parks and most recent results are presented in Scientific reports: Instagram, Flickr, or Twitter: Assessing the usability of social media data for visitor monitoring in protected areas.

Near the top of Cheat Mountain in West Virginia, bulldozer operator Bill Moore gazes down a steep slope littered with toppled conifers. Tangled roots and angled boulders protrude from the slate-colored soil, and the earth is crisscrossed with deep gouges.

The world’s largest ice sheet may be less stable than previously thought, posing an even greater threat to Florida’s coastline. The first-ever marine geologic survey of East Antarctica’s Sabrina Coast, published this week in Nature, concludes that some regions of the massive East Antarctic Ice Sheet have been sensitive to climate change for millions of years. Much like the West Antarctic Ice Sheet, this region of the East Antarctic Ice Sheet is grounded below sea level and local glaciers are experiencing ice mass loss due to ocean warming.

Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy. University of Illinois researchers have developed new, high-resolution climate models that may help policymakers mitigate these effects at a local level.

It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University–New Brunswick-led analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.

To help untangle fact from speculation, Cornell climate scientists and their colleagues have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than 30 years – occurring in the western and southwestern United States. The research was published online Dec. 8 in the Journal of Climate.

Hundreds of marine turtles die every year after becoming entangled in rubbish in the oceans and on beaches,  including plastic ‘six pack’ holders and discarded fishing gear.  

Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication in the journal PeerJ reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta. 

Populations of cheetahs in southern Africa have declined as farming and other human activities push deeper into the free-roaming cats’ range, a new study co-led by Duke University doctoral student Varsha Vijay finds.

Maps of the world’s most important wilderness areas are now freely available online following a University of Queensland and Wildlife Conservation Society-led study published today.
