Variations In Earth’s Carbon Dioxide Levels Regulated By Tropical Ecosystems
2013-07-23 13:25:45

CSIRO Rising temperatures, influenced by natural events such as El Nino, have a corresponding increase in the release of carbon dioxide from tropical forest ecosystems, according to a new study out today. The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1 degree C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on...

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

National Oceanography Centre, Southampton (UK) The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the...

Trees Use Water More Efficiently Due To CO2 Rise
2013-07-11 08:01:38

redOrbit Staff & Wire Reports - Your Universe Online Trees are becoming more efficient at using water in response to higher atmospheric carbon dioxide levels, according to new research published Wednesday in the journal Nature. In the study, researchers including Dave Hollinger from the US Forest Service's Northern Research Station (NRS) and Trevor Keenan of Harvard University analyzed direct, long-term measurements of whole-ecosystem carbon and water exchange. According to...

Researchers find that a changing atmosphere affects how much water trees require Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water, a Harvard study has found. Studies have long predicted that plants would begin to use water more efficiently as atmospheric carbon dioxide levels rose. A research team led by Research Associate Trevor Keenan and Assistant Professor of Organismic and...

Northern Biomass Of Earth Has Been Mapped And Measured
2013-06-26 07:53:13

ESA The biomass of the northern hemisphere’s forests has been mapped with greater precision than ever before thanks to satellites, improving our understanding of the carbon cycle and our prediction of Earth’s future climate. Accurately measuring forest biomass and how it varies are key elements for taking stock of forests and vegetation. Since forests assist in removing carbon dioxide from the atmosphere, mapping forest biomass is also important for understanding the global carbon...

Effects Of Predators On Carbon Cycle
2013-06-18 09:44:57

April Flowers for redOrbit.com - Your Universe Online The predator-prey relationship can affect the flow of carbon through an ecosystem, according to a new study from the Yale School of Forestry & Environmental Studies. The findings, published in Proceedings of the National Academy of Sciences, may offer a new way of looking at biodiversity management and carbon storage for climate change. The study examines the relationship between grasshoppers (herbivores) and spiders (predators)...

The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...

Scientists Uncover Secrets Of Biological Soil Crust Microbes
2013-06-14 18:39:19

Brett Smith for redOrbit.com — Your Universe Online A new study from the Lawrence Berkeley National Laboratory in Berkeley, California has found the biological soil crust (BSC) layer of a desert contains microbes that lie in wait for the ideal conditions to begin metabolic activity. “We found a way to measure from start to finish in real unaltered samples the molecular events behind the response of cyanobacterium to wetting and drying in a desert BSC,” said...

Arctic Permafrost Melts And Releases Greenhouse Gases
2013-06-11 10:18:54

Brett Smith for redOrbit.com - Your Universe Online Conditions within Arctic permafrost soils prevent dead plants and animals from decomposing, resulting in layer upon layer of organic carbon being sequestered just beneath the topsoil. However, rising Arctic temperatures are causing these soils to thaw at unprecedented rates, and NASA scientists are currently looking into just how much greenhouse gas is being released through soil decomposition. Using NASA´s C-23 Sherpa...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
