What keeps Earth-scientists busy? The present list aims at summarizing the most relevant open problems addressed by geoscientists nowadays. Some of these 49 open questions are recent; others have been standing unanswered for centuries. They cover from the early stages of the Earth to the present or near future threats; from the deeper interior of […]
Locations with an extreme climate are more sensitive to changes in the global conditions. We could say that such places live in the razor’s edge, where a subtle change makes the difference between life and death. A good laboratory for testing those ideas is Greenland. Once settled by Norsemen and Icelanders, at the end of […]
News on global warming and sea-level rise flood our daily life. Even a modest decimeter increase of the current sea level will affect millions of people . Despite this gloomy scenario, we lack precise models to predict sea level changes during glacial and interglacial periods, such as the one in which we now live. As […]
The depth of the ocean is directly related to the behavior of the tectonic plates. Studies conducted so far have assumed that the sea floor depth depends solely on its age. However, these results do not match the experimental measurements. The work developed by Adam and Vidal shows that the convective flow of the underlying […]
In addictions the first and toughest step is admitting our fault. The same applies in science: assuming our ignorance pushes us beyond the starting line, ready to delve into the unknown. So when in May 12th, 2008 a devastating earthquake struck the Sichuan province in Southwest China -labeled as ‘moderately quiet’ in terms of seismicity- […]
