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...

Photosynthesis takes place in specialized membrane systems, made up of stacked disks linked together by unstacked planar leaflets. An LMU team has now identified a protein that tucks the membrane in at the edge of each stack. By making use of sunlight to generate molecular oxygen and other energy-rich chemical compounds that other organisms can utilize as nutrients, photosynthesis provides the basis for almost all life on Earth. Radiant energy from the Sun is captured by pigment-protein...

Sharon Kleyne Hour Power of Water® Interview with Soil, Water and Garden Researcher Winston Kao. Grants Pass, OR (PRWEB) June 27, 2013 “Water your lawn at night,” says agricultural researcher Winston Kao in a recent interview on the Sharon Kleyne Hour Power of Water® radio show. The recommendation, Kao realizes, goes against nearly all available information about lawn and grass care. Kao has discovered that night lawn watering enables grass to utilize water far more...

Manganese Oxidation Played Key Role In Formation Of Oxygen On Earth
2013-06-27 07:25:47

April Flowers for redOrbit.com - Your Universe Online Oxygen is a necessary component for the survival of most terrestrial life on Earth. The planet´s atmosphere, however, did not always contain this life-sustaining substance. How and when oxygenic photosynthesis — the process responsible for producing oxygen on Earth through the splitting of water molecules — first began has been considered one of the great science mysteries of our planet. A new study, led by...

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...
