Is Biopower Carbon Neutral?

Is Biopower Carbon Neutral?

Date: July 6, 2011
Creator: Bracmort, Kelsi
Description: This report assesses the variables involved in determining whether or not biopower (i.e., electricity generated from biomass) is a carbon-neutral alternative to fossil fuels as a way to help meet meet U.S. energy demands and reduce U.S. greenhouse gas (GHG) emissions. It includes information about the biomass carbon cycle, GHG accounting for biopower production, recent developments affecting the assessment, and overview of whether or not it can be considered carbon neutral, and legislative implications.

Biochar: Examination of an Emerging Concept to Mitigate Climate Change

Biochar: Examination of an Emerging Concept to Mitigate Climate Change

Date: May 24, 2010
Creator: Bracmort, Kelsi S.
Description: Biochar is a charcoal produced under high temperatures using crop residues, animal manure, or any type of organic waste material. Depending on the feedstock, biochar may look similar to potting soil or to a charred substance. The combined production and use of biochar is considered a carbon-negative process, meaning that it removes carbon from the atmosphere. This report briefly describes biochar, its potential advantages and disadvantages, legislative support, and research and development activities underway in the United States.

Acoustic Thermometry of Ocean Climate: Marine Mammal Issues

Acoustic Thermometry of Ocean Climate: Marine Mammal Issues

Date: May 12, 1995
Creator: Buck, Eugene H.
Description: After global warming became a concern in the mid-1950s, researchers proposed measuring deep ocean temperatures to reveal any significant trends in core ocean warming. Acoustic thermometry can detect changes in ocean temperature by receiving low-frequency sounds transmitted across an ocean basin because the speed of sound is proportional to water temperature. Acoustic Thermometry of Ocean Climate, or ATOC, is an international program involving 11 institutions in seven nations. It is designed as a 30-month "proof-of-concept" project to provide data on possible global climate change, with funding provided by the U.S. Department of Defense. A debate has arisen over ATOC's impact on marine mammals versus the benefits of better global warming information derived from ATOC. This report dicusses the ATOC program and related concerns.

Ocean Acidification

Ocean Acidification

Date: May 27, 2010
Creator: Buck, Eugene H. & Folger, Peter
Description: This report discusses the increasing concern, within the scientific community, that rising levels of carbon dioxide in the atmosphere could detrimentally alter marine ecosystems. The report discusses how ocean acidification happens, its possible outcomes, as well as natural and human responses that could possibly limit or reduce the rate of the process.

Ocean Acidification

Ocean Acidification

Date: July 2, 2009
Creator: Buck, Eugene H. & Folger, Peter
Description: With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Congress is beginning to focus attention on better understanding ocean acidification and determining how this concern might be addressed.

Air Quality Issues and Animal Agriculture: EPA's Air Compliance Agreement

Date: July 12, 2005
Creator: Copeland, Claudia
Description: In an effort to collect scientifically credible data regarding the effect of animal agriculture on water resources (specifically animal waste and emissons from animal feeding operations (AFO), the Environmental Protection Agency (EPA) in January 2005 announced the Air Compliance Agreement. The agreement is intended to produce air quality monitoring data on AFO emissions during a two-year study, while at the same time protecting participants through a “safe harbor” from liability under certain provisions of federal environmental laws. This report discusses the agreement and the perspectives of both its supporters and opponents.
