*Water significant limiting factor in growing crops like switchgrass*

Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.

They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)

Researchers pursue new information from East Coast hurricane

While Hurricane Irene had officials along the East Coast preparing for mass evacuations, scientists at the Stroud Water Research Center and the University of Delaware were grabbing their best data collection tools and heading straight for the storm’s path. (more…)

Irene Highlights Critical Roles of Government, Public

EAST LANSING, Mich. — As Tropical Storm Irene shows, dealing with natural disasters is a two-way street: Both the government and the public play a critical role in curtailing the effects, according to a Michigan State University political scientist.

In her new book “Dealing with Disaster,” Saundra Schneider contends it’s not the size of the disaster or the amount of money spent on relief that determine success or failure of an emergency response. Instead, it’s the “inevitable gap” between government procedures and the collective behavior of victims. (more…)

NASA Satellite Shows a Mean Irene’s Fury

After pounding North Carolina and Virginia on Aug. 27, Hurricane Irene made a second landfall near Little Egg Inlet, N.J., early Sunday morning, Aug. 28, still as a category one hurricane with maximum sustained winds of 75 mph (120 kilometers per hour). It then weakened slightly before making a third landfall over Coney Island, N.Y. as a 65-mph (100-kilometer-per-hour) tropical storm. Irene’s heavy rains, winds and storm surge are causing widespread problems throughout the U.S. mid-Atlantic and Northeast. (more…)

Thawing Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by the end of this Century

*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.

The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21^st century as the soil warms in response to climate change. (more…)

USGS Releases New Assessment of Gas Resources in the Marcellus Shale, Appalachian Basin

The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to a new assessment by the U. S. Geological Survey (USGS).

These gas estimates are significantly more than the last USGS assessment of the Marcellus Shale in the Appalachian Basin in 2002, which estimated a mean of about 2 trillion cubic feet of gas (TCF) and 0.01 billion barrels of natural gas liquids. (more…)

Newly Discovered Icelandic Current Could Change North Atlantic Climate Picture

An international team of researchers, including physical oceanographers from the Woods Hole Oceanographic Institution (WHOI), has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could significantly influence the ocean’s response to climate change in previously unforeseen ways.

The current, called the North Icelandic Jet (NIJ), contributes to a key component of the Atlantic Meridional Overturning Circulation (AMOC), also known as the “great ocean conveyor belt,” which is critically important for regulating Earth’s climate. As part of the planet’s reciprocal relationship between ocean circulation and climate, this conveyor belt transports warm surface water to high latitudes where the water warms the air, then cools, sinks, and returns towards the equator as a deep flow.

*Drought simulator will enable in-depth testing under real-world conditions*

COLUMBIA, Mo. – Historically, droughts have had devastating effects on agriculture, causing famine and increasing consumer food costs. Now, researchers at the University of Missouri College of Agriculture, Food and Natural Resources (CAFNR) have completed two drought simulators designed to test the effects of water deficiency on crops. The simulators are located at the University of Missouri’s Bradford Research and Extension Center east of Columbia.

The simulators, part of a $1.5 million Missouri Life Sciences Research Board grant, are essentially mobile greenhouses measuring 50 feet by 100 feet. To simulate drought, researchers move the greenhouses over plants when it is raining and move them away from plants when it is sunny. A test plot of the same plants will be kept next to the simulator to provide a comparison. The drought simulators will increase the real-world application of scientific research, as they allow researchers to more closely mimic actual drought conditions. (more…)
