Arctic Tunda May Add To Greenhouse Gas Emissions
2013-10-10 13:11:36

Brett Smith for redOrbit.com – Your Universe Online Arctic tundra is often thought of as a barren wasteland that has no direct bearing on global events. However, a team of Scandinavian scientists is warning that the tundra could be a significant contributor to greenhouse gas emissions if temperatures in the Arctic continue to rise. "The soil below the tundra contains very large quantities of carbon – more than twice as much as is present in the planet's entire atmosphere,”...

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...

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target. This is according to a new study, published today, 11 July, in IOP Publishing's journal Environmental Research Letters, which shows that ambitious temperature targets can be exceeded then reclaimed by implementing BECCS around mid-century....

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...

Lawrence Livermore National Laboratory researchers have broken the record for tracking the movement and concentration of carbon dioxide in a geologic formation using the world's deepest Electrical Resistance Tomography (ERT) system. The research provides insight into the effects of geological sequestration to mitigate the impact of greenhouse gases. The team led by LLNL's Charles Carrigan obtained time lapse electrical resistivity images during the injection of more than 1 million tons...

Carbon Found To Leak From Land To Water
2013-06-11 09:35:26

April Flowers for redOrbit.com - Your Universe Online In general, scientists have thought that about half of the carbon emitted by human activities remains in the atmosphere, with the other half being stored in the oceans and on land. A new study, published in Nature Geoscience, suggests that human activity might be increasing the transition of carbon from land to rivers, estuaries and the coastal zones. This indicates that large quantities of anthropogenic carbon might be hidden in...

Boreal Forests Expected To Shift Poleward
2013-05-06 04:58:49

redOrbit Staff & Wire Reports - Your Universe Online What will happen to the climate in various parts of the world as the effects of global warming become amplified? Researchers from the Lawrence Berkeley National Laboratory have developed a new way to predict what will occur as temperatures rise across the Earth. The research, which was published in Sunday´s online edition of the journal Nature Geoscience, is anticipating major changes for boreal forests, which the authors...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
