Carbon Dioxide the Dominant Control on Global Temperature

Key Points: Because the water contained in land-based ice sheets is ultimately derived from the ocean, over long (geological) timescales global sea level is largely determined by global temperature and, consequently, the temperature-dependent volume of ice stored on land. Since the concentration of carbon dioxide in the atmosphere (The Greenhouse Effect) exerts such a powerful influence on … Seguir leyendo / Continue reading


Study Shows Rapid Warming On the West Antarctic Ice Sheet

In a discovery that raises further concerns about the future contribution of Antarctica to sea level rise, a new study finds that the western part of the ice sheet is experiencing nearly twice as much warming as previously thought. The temperature record from Byrd Station, a scientific outpost in the … Seguir leyendo / Continue reading
