Something remarkable happened on the island closest to the epicenter of the great Sumatra-Andaman earthquake last December: Only seven of the islands 78,000 inhabitants died. This is despite the fact tsunamis hit the island only eight minutes after the quake, despite the destruction of many Simuelue villages, and despite the lack of an official tsunami warning system and little in the way of telecommunications.
Why were the lives of Simuelue islanders spared when all around the I
A NASA study is offering new insight into how the Earths water cycle might be influenced by global change.
In recent years, scientists have warned that the water cycle may be affected by temperature changes, as warmer temperatures can increase the moisture-holding capacity of air.
The global water cycle involves the transfer of water molecules between the Earths land masses, cryosphere, oceans and atmosphere. Its a gigantic system powered by the su
This Friday, scientists from ICES will release a report calling for a complete overhaul of deep-sea fisheries. Scientists will recommend that all existing deep-sea fisheries should be cutback to low levels until they can demonstrate that they are sustainable. They will advise zero catch of depleted deep-sea sharks, and they will recommend that no new fisheries for deep-sea fish should be allowed until it can be demonstrated that they are capable of being sustainable.

The most comprehensive climate model to date of the continental United States predicts more extreme temperatures throughout the country and more extreme precipitation along the Gulf Coast, in the Pacific Northwest and east of the Mississippi.
The climate model, run on supercomputers at Purdue University, takes into account a large number of factors that have been incompletely incorporated in past studies, such as the effects of snow reflecting solar energy back into space and of
The ice ages made massive changes to the Earth’s landscape. But what was happening below the ice in the oceans?
Research by marine scientists reveals that it was a time of mass destruction as whole communities of animals were wiped out by ice sheets scouring the sea floor.
In the past it has been thought that these ecosystems somehow dodged extinction by recolonising from nearby habitats that escaped obliteration. But researchers at the National Oceanography Centre,
The retreat of coastlines due to rising sea levels may be accelerated by wildfires, a Duke University researcher has discovered. In the absence of such fires, forests can slow the encroachment, he found. At such fire scenes, though, finger-like patches of marshlands can extend into former forest by as much as several hundred yards. The result is a “punctuated” near-shoreline landscape, the scientist said. Such punctuated advance of the sea is in sharp contrast to the widespread belief that coastal
