Hydrologic impacts of climate change and urbanization in the Las Vegas Wash Watershed, Nevada
A cell-based model for the Las Vegas Wash Watershed in Clark County, Nevada, USA, was developed by combining the Thornthwaite water balance model and the Soil Conservation Survey's Curve Number method with pixel-based computing technology. After the model was validated, it was used to predict the 2030 and 2050 hydrologic conditions under future scenarios of climate and land-use changes. The ...

Acid mine drainage in semi-arid regions: the extent of the problem in the waters of reservoirs in the Iberian Pyrite Belt (SW Spain)
There are many reservoirs in the Iberian Pyrite Belt (IPB), SW Spain, which receive contributions from watercourses affected by acid mine drainage processes, characterised by low pH values and high concentrations of heavy metals and sulphates. When they reach the reservoirs, the waters increase its pH, which will cause most of the metal load carried by the mining channel to precipitate into the ...

The Challange of Cleaning Multi-row Commercial Coils!
The Problem: Over time multi row air conditioning and refrigeration coils (DX, chilled water, etc) can become contaminated and clogged with dirt, debris, grease, seeds, bio-film etc. These neglected multi-row coils drastically increase the HVAC system operating cost. A Pacific Gas & Electric study showed that a dirty condenser coil can increase compressor energy consumption by 30 percent. ...

EPA Tightens Chokehold On A Bruised O&G
The Obama Administration is attacking one fuel at a time, the most recent being coal and natural gas, and now methane is next on the chopping block. Methane, a component of natural gas, is burned to produce heat and electricity for many end-users, making it an important fuel source worldwide. Obama’s latest focus on methane emissions however, serve as another addition to his collection of ...

Climate change report shareholders request: Progressive action + practical steps + strong relationships = Positive experience
In the fall of 2004 DTE Energy received a request 'that a committee of independent directors of the Board assess how the company is responding to rising regulatory, competitive and public pressure to significantly reduce carbon dioxide and other emissions and report to shareholders (at reasonable cost and omitting proprietary information) by September 1, 2005.' This started an effort to document, ...

Refrigerant Gases (R-22 HCFCs): Understanding the laws regulating them
The US Clean Air Act is a congressional law that explains the EPA's task in protecting air quality and the ozone layer. This Act is maintained by the House of Representatives. Major amendments were passed in 1990 and several other changes were made after that with still more pending related to mandatory reporting of Greenhouse Gas (GHG) emissions.Refrigerant gases are those used in climate ...

Coasian economics and the management of international aviation emissions
The recent decision by the EU Parliament supporting an emissions tax and subsequent carbon trading scheme for European airlines provides the structural foundation for an exploration of the role of Coasian economics in emissions abatements in the international aviation industry. The paper begins by outlining Pigouvian taxation in aviation and considers, from a business context, the potential ...

A theoretical basis for green growth
This paper proposes a theoretical model of green growth. The paper analyses the development mechanisms through which natural resource capital regenerates (or at least does not degrade), is preserved and contributes to economic growth. Climate change is a threat to human civilisation and countries need to save natural resources, which are a crucial form of productive capital in the economy, and ...

Ex Situ Biological Treatment for Soil, Sediment, and Sludge
The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

Water and climate variability in developing countries: the case of Uganda
Water safety and climate mitigation measures are global concerns. In this study, climate variability and related health implications were examined. The data included 11,101 outpatient records in the Luwero district from the Ugandan Ministry of Health database, the records of 2,358 outpatients connected with water-related health risks linked to climate variability (diseases such as cholera, ...

Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate
The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

4 Climate factors in wind erosion control
Erosion control is vital to the well-being of any construction site or property. Unprotected soil is subject to wind erosion, and the effects of wind erosion can be detrimental to any site, resulting in safety, environmental and economic consequences. Climate factors determine which erosion control method works best for your worksite. What is wind erosion? Wind erosion is a natural process ...

Effects of climate change on aquatic invasive species and implications for management and research
Global change stressors, including climate change and variability and changes in land use, are major drivers of ecosystem alterations. Invasive species, which are non-native species that cause environmental or economic damages or human-health impacts, also contribute to ecosystem changes. The interactions between stressors and invasive species, although not well understood, may exacerbate the ...
