Most college students in the United States do not grasp the scientific basis of the carbon cycle "“ an essential skill in understanding the causes and consequences of climate change, according to research published in the January issue of BioScience. The study, whose authors include several current and former researchers from Michigan State University, calls for a new way of teaching "“ and, ultimately, comprehending "“ fundamental scientific principles such as the...

An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas. John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates. The study, published in the journal Science, indicates that methane gas...

Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in deep ocean water, a finding that could dramatically change ideas about the ocean carbon cycle. Matthew McCarthy, associate professor of ocean sciences at the University of California, Santa Cruz, led a team of researchers from several institutions who analyzed the...

By Shelley Littin, NASA Space Grant intern, University of Arizona New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use "“ knowledge that could help scientists better understand the complex carbon cycle that is at the heart of global climate warming. "Leaves have very different networks of veins. They have different shapes, different sizes, different thicknesses," said Benjamin Blonder, a doctoral student in the...

New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period. It turns out it ended up in the icy waters of the Southern Ocean near Antarctica. The findings have implications for modern-day global warming, said Ellen Martin, a UF geological sciences professor and an author of the paper, which is published in this week's journal Nature Geoscience. "It helps us understand how the carbon cycle works, which is important for...

It just got easier to pinpoint biological hot spots in the world's oceans where some inhabitants are smaller than, well, a pinpoint. Microscopic algae are called phytoplankton and range from one to hundreds of microns in size "“ the smallest being 1/100th the size of a human hair. But as tiny as they may be, communities of the phytoplankton south of Vancouver Island, British Columbia, are big players when it comes to carbon: They take up 50 percent of the carbon dioxide going from the...

A modest moss gives insight into global carbon cycling The diversity of life that can be seen in environments ranging from the rainforests of the Amazon to the spring blooms of the Mohave Desert is awe-inspiring. But this diversity would not be possible if the ancestors of modern plants had just stayed in the water with their green algal cousins. Moving onto dry land required major lifestyle changes to adapt to this new "hostile" environment, and in turn helped change global climate and...

Earth has done an ecological about-face: Global plant productivity that once flourished under warming temperatures and a lengthened growing season is now on the decline, struck by the stress of drought.NASA-funded researchers Maosheng Zhao and Steven Running, of the University of Montana in Missoula, discovered the global shift during an analysis of NASA satellite data. Compared with a six-percent increase spanning two earlier decades, the recent ten-year decline is slight -- just one...

Meteorologists have determined exactly how much carbon dioxide humans can emit into the atmosphere while ensuring that the earth does not heat up by more than two degrees The Intergovernmental Panel on Climate Change (IPCC) calculated projected temperature changes for various scenarios in 2007 and researchers at the Max Planck Institute for Meteorology in Hamburg have now gone one step further: they have developed a new model that specifies the maximum volumes of carbon dioxide that humans...
