Forest Atmosphere Carbon Transfer And Storage Facts Ii The Aspen Free Air Co2 And O2 Enrichment Face Project

This book provides an up-to-date review of the effects of increasing atmospheric carbon dioxide on agroecosystems, forests, and grasslands. It summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising CO2 will directly affect these managed ecosystems.

There is increasing interest in tools for measuring and reducing emissions of carbon dioxide, a major greenhouse gas. Two tools that have been receiving a lot of attention include carbon markets and carbon registries. Carbon registries are established to record and track net carbon emission levels over time. These registries provide quantifiable and verifiable carbon for trade within a market. This report discusses the benefits and major elements of registries and then describes a selection of existing registries and protocols with forest carbon components. The report focuses on forests because of their carbon storage potential. The purpose of this report is to provide a starting point for any state government or other party considering the development of a carbon registry with a forestry component.

Contents: (1) Background: Congressional Interest in Carbon Sequestration; (2) Carbon Cycling in Forests: The Forest Cycle; Forest Types: Tropical Forests; Temperate Forests; Boreal Forests; (3) Measuring and Altering Forest Carbon Levels: Forest Carbon Accounting; Land Use Changes; Forestry Events and Management Activities: Vegetation and Soil Carbon; Forest Events ¿ Wildfires; Forestry Practices; Wood Energy; Leakage: Land Use Leakage; Product Demand Leakage; Federal Government Programs: Federal Forests; Federal Assistance for State and Private Forestry; Federal Tax Expenditures; Federal Programs Affecting Land Use; Accounting for Forest Carbon Sequestration; (4) Conclusions. Table.

Analyzes the impacts of elevated carbon dioxide & climate change on forested ecosystems, & the economic feedbacks on harvest patterns & vegetation change on private timberlands in the U.S. Used as a framework linking general circulation model output, an ecosystem model (TEM), models of the forest sector, & a carbon accounting model. Future climates are described with output from the different models. The strong demand for wood products in the future dampens any positive growth effects on forests, for all but the maximum scenario. Charts, tables & maps.
