 Journal of PaleolimnologySediments from the Enol lake reveal more than 13,500 years of environmental history A team of Spanish researchers have used different geological samples, extracted from the Enol lake in Asturias, to show that the Holocene, a period that started 11,600 years ago, did not have a climate as stable as was believed.

NASA satellites see wind shear battering Tropical Depression Iggy NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth.

NASA's GCPEx mission: What we don't know about snow NASA's GCPEx science team is collecting as much data as they can to improve understanding of snow dynamics inside clouds, because they relate to how snow moves through Earth's water and climate cycles.

Journal of Integrated Pest ManagementIPM decreased pesticide use in University of Florida housing A new study recently published in the Journal of Integrated Pest Management shows that from 2003 to 2008, the use of insecticide active ingredients was reduced by about 90 percent in University of Florida housing buildings after an integrated pest management program was implemented.

BioScienceAre nuisance jellyfish really taking over the world's oceans? Evidence is lacking that populations of jellyfish and similar gelatinous plankton are surging in numbers globally and will likely dominate the seas in coming decades. Rather, increasing scientific and media interest as well as the lack of good baseline data seem to explain the widespread perception of an increase.

BioScienceYellow-cedar are dying in Alaska: Scientists now know why Yellow-cedar, a culturally and economically valuable tree in southeastern Alaska and adjacent parts of British Columbia, has been dying off across large expanses of these areas for the past 100 years. But no one could say why -- until now.

Applied Physics LettersWireless power could revolutionize highway transportation, Stanford researchers say A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.

TellusNew study shows correlation between summer Arctic sea ice cover and winter weather in Central Europe Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer.

Nature GeoscienceFirst plants caused ice ages New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. The research reveals the effects that the first land plants had on the climate during the Ordovician Period, which ended 444 million years ago. During this period the climate gradually cooled, leading to a series of 'ice ages'. This global cooling was caused by a dramatic reduction in atmospheric carbon, which this research now suggests was triggered by the arrival of plants. Contact: Sarah Hoyle

Warning of unrest, new study shows millions risk losing lands in Africa New studies released in London today suggest that the frenzied sell-off of forests and other prime lands to buyers hungry for the developing world's natural resources risk sparking widespread civil unrest -- unless national leaders and investors recognize the customary rights of millions of poor people who have lived on and worked these lands for centuries.

Geophysical Research LettersStudy may answer longstanding questions about Little Ice Age 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.

Geophysical Research LettersNew CU-Boulder-led study may answer questions about enigmatic Little Ice Age According to new University of Colorado Boulder-led study, the Little Ice Age began abruptly between A.D. 1275 and 1300, triggered by repeated, explosive volcanism, and was sustained for centuries by a self- perpetuating sea ice-ocean feedback system in the North Atlantic Ocean.

ScienceBiodiversity enhances ecosystems global drylands -- Ben-Gurion U researchers Study indicates ability of ecosystems in drylands worldwide to maintain multiple functions, such as carbon storage and buildup of nutrient pools (multi-functionality) is enhanced by the number of perennial plant species, mainly shrubs and dwarf-shrubs, whereas increased average annual temperature reduces this ability. This study is the first in explicitly evaluating relationships among real ecosystems at a global scale. Contact: Andrew Lavin

Nature Climate ChangeThe Arctic is already suffering the effects of a dangerous climate change Two decades after the United Nations established the Framework Convention on Climate Change in order to "prevent dangerous anthropogenic interference with the climate system", the Arctic shows the first signs of a dangerous climate change.

Nature Climate ChangeThe good news about carbon storage in tropical vegetation Tropical vegetation contains 21 percent more carbon than previously thought. Using a combination of remote sensing and field data, scientists were able to produce the first "wall-to-wall" map (with a spatial resolution of 500 m x 500 m) of carbon storage of forests, shrublands, and savannas in the tropics of Africa, Asia, and South America. Reliable estimates of carbon storage are important for the success of REDD+. Contact: Ian Vorster
