  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Ocean pH value decreasing

    A research project into ocean acidification has increased knowledge about conditions in the Baltic Sea and Kattegat-Skagerrak. When the pH value falls, the whole marine ecosystem is affected. A newly developed measurement technique provides information about natural variations in the oceans, which results in improved environmental monitoring. Since 1850 the pH value of the world’s ...

  • Scientists hone technique to safeguard water supplies

    A method to detect contaminants in municipal water supplies has undergone further refinements by two Oak Ridge National Laboratory researchers whose findings are published on line in Water Environment Research. The new work demonstrates that the technology that uses algae as sentinels has broader applications than previously reported, according to authors Miguel Rodriguez Jr. and Elias Greenbaum ...
