However, the magnitude and distribution of these terrestrial carbon sinks remained uncertain prior to a NCEAS study by Goodale and colleagues. These researchers used national forest inventories from Canada, the United States, Europe, Russia, and China to estimate the amount of carbon absorbed annually by N. Hemisphere forests. Hemisphere terrestrial carbon sink occurred in only one-third of the forested area, in regions that experience fire suppression, agricultural abandonment, and plantation forestry.
Prior to a NCEAS study by Bastviken and colleagues , freshwater and wetland ecosystems had been largely ignored in calculating global greenhouse gas budgets. Therefore, this study suggests that the continental greenhouse gas sink may be sizably overestimated. Net primary productivity NPP , the rate at which plants convert atmospheric carbon into biomass through photosynthesis, is one of the most critical components of the terrestrial carbon cycle. Del Grosso et al. Consequently, a new model was developed that provides more accurate estimates of how global NPP will respond to climate change and affect climate in the future.
As atmospheric carbon dioxide increases, changes in the global carbon cycle will impact the cycling of another important nutrient: nitrogen. However, the complexity of interactions between the carbon and nitrogen cycles makes it difficult to predict how each cycle will respond to atmospheric carbon dioxide. Through the synthesis of existing experimental data, Luo et al. This means that in some cases, the amount of carbon dioxide that can be sequestered by plants may be limited by the amount of nitrogen in the soil.
Using this framework in climate change models has the potential to reduce uncertainty about global terrestrial carbon sequestration by providing a better understanding of the role of nitrogen. Permafrost—subsurface soil that remains below freezing for two consecutive years or more—stores billions of metric tons of organic carbon.follow
Climate change alters the ecological impacts of seasons
As global temperatures rise, permafrost thaws and microbes decompose the ancient carbon, releasing methane and carbon dioxide CO 2 into the atmosphere. Our research teams have provided insights into how managers and policymakers can conserve natural resources under a changing climate. Biological reserves are intended to protect species, communities, and ecosystems in human-dominated landscapes.
