Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases — analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture — to incorporate other characteristics of ecosystems that also influence climate. "We know that forests store a lot of carbon and clearing a forest releases carbon dioxide...

Growing perennial grasses on the least productive farmland now used for corn ethanol production in the U.S. would result in higher overall corn yields, more ethanol output per acre and better groundwater quality, researchers report in a new study. The switch would also slash emissions of two potent greenhouse gases: carbon dioxide and nitrous oxide. The study used a computer model of plant growth and soil chemistry to compare the ecological effects of growing corn (Zea mays L.); miscanthus...

Researchers at the University of Illinois have developed a new, more accurate method of calculating the change in greenhouse gas emissions that results from changes in land use. The new approach, described in the journal Global Change Biology, takes into account many factors not included in previous methods, the researchers report. There is an urgent need to accurately assess whether particular land-use projects will increase or decrease greenhouse gas emissions, said Kristina...

Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where "“ and which "“ biofuel crops are used, University of Illinois researchers report this month. The researchers analyzed data from dozens of studies to determine how planting new biofuel crops can influence the carbon content of the soil. Their findings appear this month in the journal Global Change Biology Bioenergy. Plants use the sun's energy to convert carbon...


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.
