An Ancient Tool Holds Promise for Modern Water Problems
The potential effectiveness of harvesting rainwater to bolster water supply and reduce potentially polluting runoff varies greatly from place to place, even within a particular city or neighborhood. Now researchers at the Columbia Water Center have developed a tool to assess the potential of rainwater harvesting throughout the United States.

Shifting Monsoon Altered Early Cultures in China, Study Says
The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.

Project Aims to Map World’s Oceans by 2030
More than 85 percent of the ocean floor remains unmapped, leaving us in the dark about much of the earth’s topography. A global, non-profit effort will try to remedy that, and influence everything from climate research and weather prediction to mineral resource exploration and fisheries.

Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface
Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
The first Earth Day in 1970 ignited a movement to stop polluting our planet. This Earth Month, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
