A joint Australian-French study has discovered the calving of a large iceberg from the Mertz Glacier in the Australian Antarctic Territory. The iceberg -- 78 kilometres long with a surface area of roughly 2,500 square kilometres, about the size of Luxembourg -- broke off the Mertz Glacier after being rammed by another iceberg, 97 kilometres long.
The Mertz Glacier had a large crack in it for two decades. A second crack developed opposite the first in the early part of the 21st century. The collaboration studied whether these two cracks would eventually meet, and the processes that would lead to the calving of an iceberg.
A century of whaling may have released more than 100 million tonnes - or a large forest's worth - of carbon into the atmosphere, scientists say. Whales store carbon within their huge bodies and when they are killed, much of this carbon can be released.
A new study further bolsters concerns that pollution blowing across the Pacific Ocean from China and other rapidly developing Asian nations may swamp efforts to clean up the air in the Western United States and make it difficult for states and cities to meet federal standards.
Almost half of the world's primate species – which include apes, monkeys and lemurs - are threatened with extinction due to the destruction of tropical forests and illegal hunting and trade.
The cost of pollution and other damage to the natural environment caused by the world's biggest companies would wipe out more than one-third of their profits if they were held financially accountable, a major unpublished study for the United Nations has found.

The Department of Health said late Monday there appears to be "a very large area" at the Vermont Yankee nuclear reactor contaminated with radioactive tritium, and contamination levels continue to rise.
