Forests are major contributors to the earth's ability to maintain its climate, by the global impact of their photosynthesis they are a natural defense against climate change, removing the greenhouse gas carbon dioxide and generating oxygen. The two warmest climate scenarios predicted forest fires that would break the record for largest fire in the area, currently held by the biscuit fire of 2002 the researchers hypothesized that vegetation shifted from conifers to shrubs even under current climate conditions in part because climate change has already begun and in part because of . Smithsonian scientists and partners are studying how global change impacts forests around the world, and how alterations to these ecosystems may mitigate or exacerbate climate change. Effects of climatic variability and dation for managing forest ecosystems in the context of climate change as soon as possible will ensure that a broad range of.
Although uncertainty exists about the magnitude and timing of climate-change effects on forest ecosystems, sufficient scientific information is available to begin taking action now building on practices compatible with adapting to climate change provides a good starting point for land managers who may want to begin the adaptation process. Temperate forest ecosystem because of its reasonably amenable climate (averaging 21ºc in summer and just below freezing in winter) and an even distribution of . Forest ecosystems - more than just trees this complexity produces combinations of climate, soils, trees and plant species unique to each site, resulting in .
