Using evidence from an Antarctic ice core, Zebee and Caldiera calculated that over a period of 610,000 years the long-term change in atmospheric CO2 concentration was just 22 parts per million volume (ppmv), although there were larger fluctuations … [Read more...] about Earth’s CO2 Balance

The latest research from scientists in Antarctica reveals the deep ocean around the frozen continent is becoming less salty and that this could play a major role in changing ocean currents and the climate. New details about changes to salinity are … [Read more...] about Satellite Tagged Seals Collect Data from Ocean Around Antarctica
