New forecasts on rising sea levels suggest that New York will be a big loser, while some regions, including those closer to polar regions, will win big, reports BBC News.. A 2007 report from the Intergovernmental Panel on Climate Change forecast sea levels to rise by as much as 1 foot by 2100. But that forecast was a global average. A Dutch team has now made an attempt to model all the factors leading to regional variations. And whatever the global figure turns out to be, there will be...

Scientists have calculated that the Earth sees about 760 thunderstorms every hour. The figure is substantially lower than numbers that have been used for nearly a century. The new research, which was unveiled at a recent European Geosciences Union meeting, uses a global network of monitoring stations that detect the electromagnetic pulses produced by major bolts of lightning. The scientists confirmed that thunderstorms are mainly a tropical phenomenon, and the Congo basin is the global...

According to new research, whitening clouds by spraying them with seawater could do more harm than good for climate change. Whiter clouds reflect more solar energy back into space, which inevitably cools the Earth. However a study presented at the European Geosciences Union meeting found that using water droplets of the wrong size would lead to warming, not cooling. One scientist said it should be possible to make sure droplets were the correct size. John Latham of the University...

The Chicxulub crater in Mexico, the site of the asteroid strike that brought the dinosaurs to extinction 65 million years ago, is among the highlights of ocean drilling projects proposed for the next decade, reports BBC News. The Integrated Ocean Drilling Program (IODP) plans to study the crater by drilling about a mile into the sea bed. IODP is also planning expeditions to study earthquakes, ancient climates and a long-term aim to penetrate the Earth's mantle for the first time. IODP...

Two members of the MESSENGER team have been honored by their peers. Carl Jack Ercol, the man largely responsible for ensuring that MESSENGER can withstand solar radiation up to 11 times greater than at Earth as it orbits the planet closest to the Sun, has received the 2008 SAE Arch T. Colwell Merit Award. Independently, MESSENGER Co-Investigator James W. Head, III, was awarded the Runcorn-Florensky Medal by the European Geosciences Union (EGU) at their General Assembly earlier this month. SAE...

The volcanic activity that has recently happened in Iceland is making the case for a new satellite tracking instruments. As ash from Eyjafjallajokull grounded more flights this week, Dr. Fred Prata, a remote sensing expert, told an Earth sciences meeting in Vienna that current monitoring from space was good but not good enough. "Of the present suite of satellite instruments, none were developed for the volcanic ash problem," he said. "Therefore, they are sub-optimal for detecting and...

On May 2-7, 7000 researchers from all of Europe gather in Vienna for European Geosciences Union. This is a great opportunity to exchange information and experiences on the ash cloud from the Icelandic volcano. A scientist from Risø DTU seized the opportunity and organized a special session at the conference. It is bad for the air traffic in Europe. But research can learn a lot from the ash cloud from Eyjafjallajökull in Iceland that has been floating around in the atmosphere. It...

Scientists have uncovered evidence contained within South African rocks which shows that a weak magnetic field was present on Earth nearly 3.5 billion years ago. The evidence in question was found inside of dacite rocks from the Barberton mountain range by University of Rochester professor John Tarduno and a team of researchers. The discovery was presented during the European Geosciences Union conference in Vienna, Austria, and was also the topic of a May 4 article by BBC News science...

Earth-bound tornadoes are puny compared to "space tornadoes," which span a volume as large as Earth and produce electrical currents exceeding 100,000 amperes, according to new observations by a suite of five NASA space probes. The probe cluster, called Time History of Events and Macroscale Interactions during Substorms (THEMIS), recorded the extent and power of these electrical funnels as the probes passed through them during their orbit of Earth. Ground measurements showed that the space...

Up to now, the oceans have buffered climate change considerably by absorbing almost one third of the worldwide emitted carbon dioxide. The oceans represent a significant carbon sink, but the uptake of excess CO2 stemming from man's burning of fossil fuels comes at a high cost: ocean acidification. Research on ocean acidification is a newly emerging field and was one of the major topics at this year's European Geosciences Union (EGU) General Assembly held in Vienna in April. The European...

  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
