Endangered glaciers: Alpine ice begins Antarctic voyage. More than 400 pieces of Alpine ice have been moved to a giant freezer - a first step in their journey to Antarctica.
The seemingly strange plan to send ice to the coldest place on Earth is part of a scientific mission to "rescue" some of the world's most endangered glacial ice. Bubbles in old, deep glacial ice are frozen records of our past atmosphere. Scientists say their purpose-built Antarctic ice bunker will keep these safe for future research.

The Gulf Coast of the United States is the coastline along which the Southern United States meets the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the Gulf States. The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism.

USGS Gulf of Mexico Science Coordination - Barrier Island Comprehensive Monitoring (BICM) The form of Louisiana’s coast is a function of the dynamic balance between the Mississippi River and the Gulf of Mexico.
Barrier Islands, beaches, and mainland shorelines constantly change in response to river discharge, sea level, waves, and the actions of man. Hurricane protection, unique habitats, and large estuaries exist due to the presence of these important coastal landforms. Louisiana's barrier islands, beaches, and mainland shorelines define the boundary of program is designed to monitor Louisiana's dynamic coastline. BICM will provide an important tool to plan and monitor the performance of coastal protection and resotration projects built to date and envisioned for the future. Important components monitored by BICM include bathymetry, topography, shoreline change, habitats, and storm assessment protocol. Cosmic clue to UK coastal erosion. Image copyright Martin Hurst et al Recent centuries have seen a big jump in the rates of erosion in the iconic chalk cliffs on England's south coast.
A new study finds that for thousands of years the rocks were being beaten back by the waves at perhaps 2-6cm a year. The past 150 years has seen this retreat accelerate 10-fold, to more than 20cm a year. The speed-up was clocked with the aid of a smart technique that tracks changes induced in rocks when they are exposed to energetic space particles.
Nepal drains dangerous Everest lake. Image copyright Department of hydrology and meteorology Nepal's army says it has finished draining a dangerous glacial lake near Mount Everest to a safe level.
The Imja glacial lake, at nearly 5,000m (16,400ft) high, was in danger of flooding downstream settlements, trekking trails and bridges. Coast Lines. Coasts are a more complex geographical entity than you might believe.

In Indonesia, a Wetlands International project uses permeable dams to restore sediment needed for the trees to grow. The charity says early results suggest "ecological restoration" is more effective than planting programmes. The Economist explains: What is Africa’s “Great Green Wall”?

Jurassic Coast beaches face closure if visitors fail to use 'common sense', experts warn.
Beaches on Dorset's famous Jurassic Coast could be shut if tourists do not start to exercise ‘common sense’ and listen to safety warnings when visiting the Unesco World Heritage Site.
Repeat Photography Project. Public domain The Repeat Photography Project began in 1997 with a systematic search of the archives at Glacier National Park.
We began searching for historic photographs of glaciers in the vast collection that spans over a century. Many high quality photographs exist from the parks early photographers such as Morton Elrod, T.J. Hileman, Ted Marble, F.E. Matthes, and others who scoured the park to publicize its beauty and earn their livings. Map showing glaciers re-photographed by USGS since 1997. What’s happening to Europe’s longest glacier? The mighty Aletsch Glacier is melting at an ever-quickening pace and could almost disappear by the end of this century.
The shrinking field of ice is just one of a series of dramatic changes to the local region’s landscape and fauna. From the top of the Moosfluh peak above the village of Riederalp, the sweeping panoramic vista takes your breath away. A huge grey-and-white cracked sea of ice snakes into view from around a distant mountain. Just below, an elderly Japanese couple munch away on their packed lunch, silently digesting the natural wonder from their balcony seat.
“I’ve been here three times in the past 17 years and each time it looks a bit different,” says the man. Stretching over 23 kilometres, the Aletsch Glacier in canton Valais is the longest in Europe, measuring 1.5 kilometres wide on average and 900 metres at its thickest point.
