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 change would be gradual due to sea-level rise.
The researchers findings about the impact of wildfires raise questions about whether fire suppression or controlled periodic burning are the best strategies in areas being gradually inundated by rising seas resulting from global warming, said Benjamin Poulter. He is a research scientist at Dukes Nicholas School of the Environment and Earth Sciences as well as a visiting lecturer at the University of North Carolina at Chapel Hill.
Poulter will describe his findings during a 5:45 p.m. talk on Thursday, Oct. 20, 2005, during an Estuarine Research Federation conference at the Marriott Waterside Hotel and Convention Center in Norfolk, Va. His research was mostly funded by NASA.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
