New findings reveal that the U.S. shoreline -- from Virginia to Florida -- has been uplifted by more than 210 feet, meaning less ice melted than expected. This is big news for scientists who use the coastline to predict future sea-level rise.
The recent discovery of a bacterium that is able to thrive at minus 15 degrees Celsius, the coldest temperature ever reported for bacterial growth, is exciting because it offers clues about some of the necessary preconditions for microbial life on Mars.
Three NASA-built instruments that are integral components of the next in a series of U.S./European ocean altimetry satellites have arrived in France for integration with their spacecraft in preparation for a 2015 launch. Jason-3 will extend the two-decade series of satellites that are tracking global sea level changes and enabling more accurate weather, ocean and climate forecasts.
The winds of the quasibiennial oscillation in the tropical upper atmosphere have greatly weakened at some altitudes over the last six decades, according to a new study. The finding is consistent with computer model projections of how the upper atmosphere responds to global warming induced by increased greenhouse gas concentrations.
Ammonium salts could provide a viable way of removing carbon dioxide from the atmosphere via carbon mineralization, studies suggest.
Life scientists provide important new details on how climate change will affect interactions between species in newly published research. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.
Concerns continue to grow about the effects of climate change on fire. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected by some studies. Of equal concern to scientists and policymakers alike are the atmospheric effects of wildfire emissions on climate.
In two critical reports released at the Arctic Council Ministerial Meeting in Kiruna, Sweden on May 15th, scientists helped inform an international body of senior government officials about changing conditions in the Arctic, and potential responses to those changes.
Researchers have found evidence of a major cosmic event near the end of the Ice Age. The ensuing climate change forced many species to adapt or die.
Woody plant matter is almost completely digested by bacteria living in the Amazon River. This tough stuff plays a major part in fueling the river's breath. The finding has implications for global carbon models, and for the ecology of the Amazon and the world's other rivers. Until recently, people believed much of the rainforest's carbon floated down the Amazon River and ended up deep in the ocean.
