Strategies for Increasing Carbon Stored in Forests and Wood

While the U.S. and other world leaders consider options for offsetting carbon emissions, it is important to take into account the role forests play in the global carbon cycle, say scientists in a paper published in the spring edition of Issues in Ecology. Currently, the carbon stored in forests and harvested wood products offsets 12-19 percent of U.S. fossil fuel emissions—growth primarily the result of recovery from the large scale harvesting that occurred around 100 years ago. These high offsets are not permanent but have the potential to increase; however, not without tradeoffs.

“Several strategies for offsetting carbon emissions have been proposed or are currently being implemented in the U.S.,” says Mike Ryan from the United States Department of Agriculture, Forest Service and lead author of the paper. “Some of the important tradeoffs are worth mentioning because many people have viewed forests as a simple and uncomplicated partial solution to reducing CO2 in the atmosphere, and they are not.”

Mike Ryan and colleagues discuss eight strategies being used or proposed in the U.S., and the risks, uncertainties and tradeoffs of each. These include avoiding deforestation, afforestation (planting or replanting forests), decreasing harvests, increasing the growth rate of existing forests, using biomass energy from forests to reduce carbon emissions, using wood products in place of concrete or steel for building materials, implementing urban forestry and using fuel management to reduce fire threats.

Survey - Basic Scientific Knowledge Sadly Lacking in US

basic-scientific-knowledge-sadly-lacking-in-usAre Americans flunking science? A new national survey commissioned by the California Academy of Sciences and conducted by Harris Interactive reveals that the U.S. public is unable to pass even a basic scientific literacy test.

Over the past few months, the American government has allocated hundreds of billions of dollars for economic bailout plans. While this spending may provide a short-term solution to the country’s economic woes, most analysts agree that the long-term solution must include a transition to a more knowledge-based economy, including a focus on science, which is now widely recognized as a major driver of innovation and industry. Despite its importance to economic growth, environmental protection, and global health and energy issues, scientific literacy is currently low among American adults. According to the national survey commissioned by the California Academy of Sciences: (more…)
