A new study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has largely replaced small farmers in doing most of the tree cutting in Brazil and Indonesia, which may make it easier to rein in the trend.

The European Space Agency's Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on 4 August 2010. A new animation shows that the iceberg, the largest in the northern hemisphere, is now entering Nares Strait -- a stretch of water that connects the Lincoln Sea and Arctic Ocean with Baffin Bay.

A new study looks at how living close to the border affects people, and whether borderland people are different from other people. The case in point is the Russians on the Kola Peninsula: Living in the high north, hailing from the south, and with Scandinavian neighbours within throwing distance across an increasingly permeable border. How do they view themselves?

Britain is leading the world in green burials as more and more people decide to be laid to rest in woodlands, meadows, farmlands and other habitats which are rich in wildlife – and there are no laws preventing it as there are in many other countries. New research shows that people choose green burials because of sustainability, to be in a pleasant, peaceful place which means something to them, or because local cemeteries are full.
Satellite Data Reveals Why Migrating Birds Have a Small Window to Spread Bird Flu

In 2005 an outbreak of the H5N1 ‘bird flu’ virus in South East Asia led to widespread fear with predictions that the intercontinental migration of wild birds could lead to global pandemic. Such fears were never realised, and now new research reveals why the global spread of bird flu by direct migration of wildfowl is unlikely, while also providing a new framework for quantifying the risk of avian-borne diseases.
