NASA teleconference on sea level change warns of rising oceans

By - August 27, 2015 4 Pictures

On Aug. 26, NASA held a media teleconference regarding current predictions on sea level rise, highlighting the risks to coastal populations in low-lying areas, and the inherent problems in creating reliable global models. A panel of experts from NASA's recently-founded Sea Level Change Team tells us that ocean levels are inexorably on the rise, but gaps in our understanding and ability to survey risk regions mean we don't know just how fast the change will take place.

European climate at mercy of retreating sea ice

By - June 30, 2015

An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region. This, it warns, could result in a cooler climate in western Europe and an altered or slower Atlantic Meridional Overturning Circulation (AMOC), which would have knock-on effects for the Gulf Stream and consequently for the atmosphere.
