Scientists from the Department of Energy's Pacific Northwest National Laboratory will present research related to climate change, wind power, carbon sequestration and more at the 2011 American Geophysical Union Fall Meeting, which runs Monday, Dec. 5 through Friday, Dec. 9 at the Moscone Convention Center in San Francisco. Summaries of some of PNNL's presentations are below.
Understanding Human and Environmental Systems at Regional Scales
As the Earth's climate system responds to increased atmospheric greenhouse gases, changes will occur to different regions of the world. Crops may fail in one area and blossom in another, fresh water might become rare or instead flood human settlements or reservoirs, or the demand for energy might overwhelm some power systems as cooling and heating needs change. To aid decision-makers such as politicians and resource managers better understand their options, PNNL researcher Kathy Hibbard and colleagues are developing a framework that knits together climate, economics, human and natural resources on regional scales. Various models of regional climate, crop productivity, socio-economics, energy and technology changes form the skeleton of an integrated Regional Earth System Model, or iRESM. The computational challenges of putting these models together will require novel solutions. For example, one model component divides the United States up into equal grids while others use state boundaries or utility zones. The time scales that different models use to simulate events range from seconds to years to decades. Using a 10-state region in North America as a pilot study, the research team from PNNL and the Joint Global Change Research Institute in College Park, Md., will be guided by needs of stakeholders to build a modeling framework that analyses supply and demand of variables related to water, food, energy, and buildings.
