Future ice ages may be delayed by up to half a million years by our burning of fossil fuels. That is the implication of recent work by Dr Toby Tyrrell of the University of Southampton's School of Ocean and Earth Science at the National Oceanography Centre, Southampton.

Fairbanks adventurer Roger Siglin has journeyed close to the magnetic north pole. Near Resolute, in the northern area of Canada now known as Nunavut, Siglin was 300 miles from the magnetic north pole, the wandering spot on Earth's surface that attracts compass needles and confounds scientists.

A breakthrough in geological dating can be expected within the next few years, combining existing methods to yield higher accuracy over longer time scales closer to the earth's origin. This will bring great benefits not just for earth sciences, but also for other fields that rely on accurate dating over geological time. The developments ushering in a new generation of dating methods were discussed at a recent workshop on geochronological timing organised by the European Science Foundation (ESF).

A combination of geological and biological findings are lending weight to the possibility that the Chatham Islands were under water until three million years ago, and that New Zealand's flora and fauna may have evolved in another large island near New Zealand.

High-speed ruptures travelling along straight fault lines could explain why some earthquakes are more destructive than others, according to an Oxford University scientist. In this week's Science, Professor Shamita Das suggests that ruptures in the Earth's surface moving at 6km per second could make future earthquakes along California's San Andreas fault much more destructive than current models predict.

 | New scientific findings suggest that a large comet may have exploded over North America 12,900 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of much of the planet and the extinction of large mammals. ...> Full Article |
 | A reversal of tectonic plate motion between Acapulco and Mexico City in the last half of 2006 probably didn't ease seismic strain in the region or the specter of a major earthquake anticipated there in the coming decades, says a University of Colorado at Boulder professor. ...> Full Article |
 | Perhaps it was just a matter of sympathy, but tremors rippled the landscape of Vancouver Island, the westernmost part of British Columbia, in 2002 during a major Alaskan earthquake. Geoscientists at the University of Washington have found clear evidence that the two events were related. ...> Full Article |
 | Geologists learn by looking at rocks. Of course, it's not that simple. Here in Minnesota, the tapestry of mineral-laden geology lies buried under forests, soils and parking lots. ...> Full Article |
