Iron is key to reversing global warming, Concordia and McGill research shows Canada defines itself as a nation that stretches from coast to coast to coast. But can we keep those coasts healthy in the face of climate change? Yves Gélinas, associate professor in Concordia´s Department of Chemistry and Biochemistry, has found the solution in a surprising element: iron. In a study published in Nature, Gélinas – along with Concordia PhD candidate Karine...

Fifteen years of studying two experimental wetlands has convinced Bill Mitsch that turning the reins over to Mother Nature makes the most sense when it comes to this area of ecological restoration. Mitsch, an environment and natural resources professor at Ohio State University, has led the effort to compare the behavior of two experimental marshes on campus — one that was planted in 1994 with wetland vegetation and another that was left to colonize plant and animal life on its own....

Geologists are hoping to learn a great deal about geologic carbon sequestration from injecting 1 million metric tons of carbon dioxide into sandstone 7,000 feet beneath Decatur, Ill. And they're hoping the public learns a lot from the endeavor, too. The Illinois Basin — Decatur Project (IBDP) began its injection, the first million-ton demonstration from an industrial source in the U.S., in November 2011. Over the next three years, the Midwest Geological Sequestration Consortium, led...

A new study comparing the carbon-holding power of freshwater wetlands has produced measurements suggesting that wetlands in temperate regions are more valuable as carbon sinks than current policies imply, according to researchers. The study compared several wetlands at two Ohio wetland sites: one composed of mostly stagnant water and one characterized by water regularly flowing through it. The study showed that the stagnant wetland had an average carbon storage rate per year that is almost...

Scientists are reporting discovery of an improved way to remove carbon dioxide – the major greenhouse gas that contributes to global warming – from smokestacks and other sources, including the atmosphere. Their report on the process, which achieves some of the highest carbon dioxide removal capacity ever reported for real-world conditions where the air contains moisture, appears in the Journal of the American Chemical Society. Alain Goeppert, G. K. Surya Prakash, chemistry...

Scientists Subject Rocks To Hellish Conditions To Combat Global Warming

A team of Earth scientists at Stanford University is subjecting chunks of rock to hellish conditions in the laboratory — all in the name of curbing climate change. By exposing a handful of rocks to high temperatures and pressures, the scientists have obtained critical new data about the large-scale underground storage of carbon dioxide, a potent greenhouse gas and leading cause of global warming. "About 60 percent of the world's carbon dioxide emissions come from power plants,...

Diminishing nature's carbon storage Australian scientists have reconstructed the past six thousand years in estuary sedimentation records to look for changes in plant and algae abundance. Their findings, published in Global Change Biology, show an increase in microalgae relative to seagrass in the past 60 years. This shift could diminish the ability of estuaries, which are natural global carbon sinks, to mitigate climate change. According to Dr. Peter Macreadie, University of...

Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent. The breakthrough comes from expressing certain genes in algae that increase the amount of photosynthesis in the plant, which leads to more biomass. Expressing genes means that the gene's function is turned on. "The key to this (increase in biomass) is combination of two genes that increases the photosynthetic carbon conversion into organic matter by 50...

Woods Hole Oceanographic Institution (WHOI) scientists have found that carbon is stored in the soils and sediments of the Ganges-Brahmaputra basin for a surprisingly long time, making it likely that global warming could destabilize the pool of carbon there and in similar places on Earth, potentially increasing the rate of CO2 release into the atmosphere. The study, published in the current online edition of Nature Geoscience, examined the radiocarbon content of river sediments collected...

The largest and most comprehensive study yet done on the effect of biofuel production from West Coast forests has concluded that an emphasis on bioenergy would increase carbon dioxide emissions from these forests at least 14 percent, if the efficiency of such operations is optimal. The findings are contrary to assumptions and some previous studies that suggest biofuels from this source would be carbon-neutral or even reduce greenhouse gas emissions. In this research, that wasn't true in...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
