Geotimes April 2007 Carolyn Gramling	Ice Twists Under Pressure Confined inside tiny, hollow cylinders called carbon nanotubes, and subjected to high pressures similar to those found at a planet's core, water freezes into tiny ice spirals that resemble the DNA double helix, a new study shows.
Geotimes April 2007 Kathryn Hansen	Ocean Waves Drive Earth's Hum High-energy near-shore waves are the main source of energy for the constant seismic background noise known as Earth's "hum."
Geotimes April 2007 Sally Adee	Rainfall Affected by Climate Change Global climate change will likely cause significant changes in the world's rainfall patterns, according to researchers working on the Intergovernmental Panel on Climate Change Fourth Assessment Report summary.
Geotimes April 2007 Megan Sever	Ancient Glaciers Melting Quickly Peru's Qori Kalis is one of the few remaining tropical glaciers, and it may be gone in five years, reported a glaciologist at Ohio State University. The melting of the Quelccaya Ice Cap poses new hazards to the people living in valleys below the peak.
Geotimes April 2007 Carolyn Gramling	Wallace Broecker: Changes in the Atmosphere An interview with an expert on issues of climate change about his experiences advising politicians about the consequences of climate change and his hopes for new technologies of carbon sequestration.
Chemistry World April 2007 Mark Peplow	Editorial: Swindled? The bottom line is that just a few degrees increase in global average temperatures is likely to have a severe impact on human life. The silver lining of anthropogenic climate change is that, being man-made, at least we stand a chance of doing something about it.
IEEE Spectrum April 2007 Sandra Upson	U.S. Earth-Sensing Satellites Left Out In the Cold The degree of precision needed to forecast hurricanes, and the future accuracy of climate modeling as well, may be in danger if recent trends in Earth-observing satellite programs persist.
IEEE Spectrum April 2007	Glacier Power As an island country, Iceland would face difficult challenges in exporting energy. So instead, the country's government is importing manufacturers that need energy, the idea behind the Karahnjukar hydropower project.
Science News March 31, 2007	Science Safari: The Billion Tree Campaign The United Nations Environment Program has launched a major global tree-planting campaign to encourage tree-planting pledges online.
Geotimes March 2007 Margaret Putney	OneGeology: A Site for All In partnership with the United Nations' International Year of Planet Earth, geologists around the world are coming together to form a world geological map, accessible to all on the Internet.
