Analysis of Climate Policy Targets under Uncertainty
(MIT Joint Program on the Science and Policy of Global Change, 2009-09)Although policymaking in response to the climate change is essentially a challenge of risk management, most studies of the relation of emissions targets to desired climate outcomes are either deterministic or subject to a ... -
Are Land-use Emissions Scalable with Increasing Corn Ethanol Mandates in the United States?
(MIT Joint Program on the Science and Policy of Global Change, 2016-04)In response to the Renewable Fuel Standard, the U.S. transportation sector now consumes a substantial amount (13.3 billion gallons in 2010) of ethanol. A key motivation for these mandates is to expand the consumption of ... -
Consequences of Considering Carbon/Nitrogen Interactions on the Feedbacks between Climate and the Terrestrial Carbon Cycle
(MIT Joint Program on the Science and Policy of Global Change, 2007-06)A number of observational studies indicate that carbon sequestration by terrestrial ecosystems in a world with an atmosphere richer in carbon dioxide and a warmer climate depends on the interactions between the carbon and ... -
Description and Evaluation of the MIT Earth System Model (MESM)
(MIT Joint Program on the Science and Policy of Global Change, 2018-02)The MIT Integrated Global System Model (IGSM) is designed for analyzing the global environmental changes that may result from anthropogenic causes, quantifying the uncertainties associated with the projected changes, and ... -
Global Economic Effects of Changes in Crops, Pasture, and Forests due to Changing Climate, Carbon Dioxide, and Ozone
(MIT Joint Program on the Science and Policy of Global Change, 2007-05)Multiple environmental changes will have consequences for global vegetation. To the extent that crop yields and pasture and forest productivity are affected there can be important economic consequences. We examine the ... -
Methane Fluxes Between Terrestrial Ecosystems and the Atmosphere at Northern High Latitudes During the Past Century: A retrospective analysis with a process-based biogeochemistry model
(MIT Joint Program on the Science and Policy of Global Change, 2004-03)We develop and use a new version of the Terrestrial Ecosystem Model (TEM) to study how rates of methane (CH4) emissions and consumption in high-latitude soils of the Northern Hemisphere have changed over the past century ... -
MIT Integrated Global System Model (IGSM) Version 2: Model Description and Baseline Evaluation
(MIT Joint Program on the Science and Policy of Global Change, 2005-07)The MIT Integrated Global System Model (IGSM) is designed for analyzing the global environmental changes that may result from anthropogenic causes, quantifying the uncertainties associated with the projected changes, and ... -
Past and Future Effects of Ozone on Net Primary Production and Carbon Sequestration Using a Global Biogeochemical Model
(MIT Joint Program on the Science and Policy of Global Change, 2003-10)Exposure of plants to ozone inhibits photosynthesis and therefore reduces vegetation production and carbon sequestration. Simulations with the Terrestrial Ecosystem Model (TEM) for the historical period (1860-1995) show ... -
Probabilistic Forecast for 21st Century Climate Based on Uncertainties in Emissions (without Policy) and Climate Parameters
(MIT Joint Program on the Science and Policy of Global Change, 2009-01)The MIT Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model's first projections were published in 2003 substantial improvements have been made to ... -
A Process-based Analysis of Methane Exchanges Between Alaskan Terrestrial Ecosystems and the Atmosphere
(MIT Joint Program on the Science and Policy of Global Change, 2003-11)We developed and used a new version of the Terrestrial Ecosystem Model (TEM) to study how rates of methane (CH4) emissions and consumption in Alaskan soils have changed over the past century in response to observed changes ... -
A Strategy for a Global Observing System for Verification of National Greenhouse Gas Emissions
(MIT Joint Program on the Science and Policy of Global Change, 2011-06)With the risks of climate change becoming increasingly evident, there is growing discussion regarding international treaties and national regulations to lower greenhouse gas (GHG) emissions. Enforcement of such agreements ... -
Unintended Environmental Consequences of a Global Biofuels Program
(MIT Joint Program on the Science and Policy of Global Change, 2009-01)Biofuels are being promoted as an important part of the global energy mix to meet the climate change challenge. The environmental costs of biofuels produced with current technologies at small scales have been studied, but ...
