The University of Alabama in Huntsville scientists use data gathered by NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.
In a paper recently published in the journal BioScience, Richard B. Primack, professor of biology at Boston University, and Abraham J.

An ocean mapping expedition has shed new light on deepest place on Earth, the 2,500-kilometer long Mariana Trench in the western Pacific Ocean. Using a multibeam echo sounder, scientists found four “bridges” spanning the trench and measured its deepest point with greater precision than ever before.
More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds.
The Atima, Honduras plant, under construction, is the eighth project of AguaClara, Cornell's international small-scale water treatment design team that has been working since 2005 in Honduras, where 60 to 70 percent of people do not have access to clean water. So far, AguaClara plants serve about 25,000 people.

A giant experiment is under way at the Tyson Research Center, Washington University in St. Louis’ 2,000-acre outdoor laboratory for ecosystem studies. The experiment will test three different variables in 32 glades with the goal of establishing best practices for restoring not just degraded glade habitats but degraded ecosystems in general.
A new international study, with NCAR co-authors, suggests that the Little Ice Age was triggered by an unusual, 50-year episode of four massive volcanic eruptions. This led to an expansion of sea ice and a related weakening of Atlantic currents that caused the cool period to persist for centuries.
National parks help preserve species native to a particular region, but it appears that some species preservation is more successful if a significant portion of land adjacent to a park also is left as natural habitat.
Nova Southeastern University and Florida International University researchers collaborate on long-term sustainability study to prepare for an oil spill that could catastrophically impact Florida
The economic pain of a flattening oil supply will trump the environment as a reason to curb the use of fossil fuels, say two scientists, one from the University of Washington and one from the University of Oxford in the United Kingdom, in the Jan. 26 issue of the journal Nature.
The effects of burning on rangelands have long been debated. Although it is desirable to remove woody plants and invasive species, fire may also eliminate the native grasses that are important for raising cattle. Studying the effects of burning over a span of years can inform land managers how rangelands will respond to this type of management.
A new study comparing the carbon-holding power of freshwater wetlands has produced measurements suggesting that wetlands in temperate regions are more valuable as carbon sinks than current policies imply.
University of Arkansas law professor Susan Schneider calls for a major transformation of U.S. agricultural law and policy. The central goal of both should focus on sustainable production and delivery of healthy food to consumers.
New research demonstrates that one suggested method of geoengineering the atmosphere to deal with climate change, injecting sulfate particles into the stratosphere, probably would have limited success.
Johns Hopkins University environmental engineer Edward J. Bouwer is available to speak to reporters wondering what could happen to the gasoline and oil on board the Costa Concordia if fuel starts to leak from the wrecked cruise ship.
A study found that the more information companies disclose about their sustainable practices, the more they are viewed as being environmentally friendly -- even if their actual environmental performance is not strong.
Researchers from the Wildlife Conservation Society and Okapi Wildlife Associates have conducted an exhaustive global study of human consumption of marine mammals using approximately 900 sources of information. The main finding: since 1990, people in at least 114 countries have consumed one or more of at least 87 marine mammal species.
A large group of researchers gathered at the Virginia Institute of Marine Science to integrate and refine field measurements and computer models of carbon cycling in the waters along the U.S. East Coast.

2011 was the ninth warmest year (globally averaged) in the 33-year global satellite record despite La Niña Pacific Ocean cooling events at the start and finish of the year.
A hemispherewide phenomenon – and not just regional forces – has caused record-breaking amounts of freshwater to accumulate in the Arctic’s Beaufort Sea.
Weed control has become a matter of national security. Along U.S. southern coastal rivers, most particularly Texas’ Rio Grande, an invasive species of plant known as giant reed is encroaching on the water, overrunning international border access roads, and creating a dense cover for illegal activities. The U.S. Department of Homeland Security has called for a plan to control this weed.
