Evaluation of Impacts of Climate Variability and Change at NASA Ames Research Center in Silicon Valley California

This ongoing project focuses on evaluating the impacts of climate variability and change on the mission and operations of the NASA Ames Research Center (NASA ARC) located in Silicon Valley, California (following Executive Order 13514, 2009). NASA ARC is vulnerable to climate change due to its locati ..... More

Assessment of Risk, Legal Issues, and Insurance for Geologic Carbon Sequestration in Pennsylvania

The potential human-health, safety, and environmental risks associated with (1) CO2 capture at power plants and large industrial sources; (2) transport via pipeline to geologic storage sites; (3) injection into subsurface formations; and (4) after closure of storage sites was conducted on a comprehe .....

Evaluating Sustainability of Projected Water Demands in 2050 Under Climate Change Scenarios

Tetra Tech performed an assessment of climate change impacts to water supplies in the United States which is to appear as a peer-reviewed paper in Environmental Science and Technology. ..... More

Climate Change Study on Los Angeles Aqueduct System

Tetra Tech has been working with LADWP to analyze the impacts of climate change on water supplies from the Eastern Sierra Nevada, and to evaluate adaptation strategies to address the impacts of such changes. Precipitation from the Eastern Sierra Nevada is one of the main water sources, and the one o ..... More

Conceptual Model of Ocean Iron Fertilization

Discharge of “greenhouse” gases (carbon dioxide, methane, nitrous oxide, etc.) into the atmosphere, mostly from fossil fuel combustion, agriculture, and forestry practices has produced the highest concentrations experienced in at least the last 800,000 years. No single technique appears likely to co ..... More

CO2 Pipeline Risk Evaluation

Vattenfall built a 30 MW pilot plant to test oxy-fuel combustion processes with lignite and other types of coal. Tetra Tech used the pipeline-walk algorithm developed for the US DOE FutureGen project to evaluate potential risks from pipeline leaks or ruptures. Multiple routes for the pipeline in the ..... More

Final Risk Assessment Report for the FutureGen Environmental Impact Statement

FutureGen represents a technological advancement that integrates advanced coal gasification technology, the production of hydrogen from coal, electric power generation, carbon dioxide capture, and subsequent geologic storage. Carbon capture and sequestration (CCS) technology is an innovative method ..... More

Climatic Change Impacts on Small Island States in the Indian and Atlantic Oceans

For the United Nations, we evaluated the information available to analyze climate change impacts on the water resources of the Cape Verde Islands, Madagascar, Mauritius, Comoros, the Seychelles, and the Maldives. Sea level change is thought to be one of the most important climate related changes tha ..... More

Predicted Changes in Relative Sea Level Due to Climatic Change

A major consequence of the increase in worldwide temperatures resulting from greenhouse gas increases is a potential rise in sea level due to thermal expansion of ocean water and melting ice caps and mountain glaciers. Islands are more exposed to climate change repercussions due to their elevation, ..... More

Potential Hurricane Impacts on California due to Global Warming

Hurricanes generated in the northeastern Pacific Ocean off the coast of Central America have not impacted the continental U.S. but most have traveled in a more westerly path towards the Hawaiian Islands. In fact, the only hurricanes to make landfall in the U.S. in the 20th century did so along eithe ..... More
