Our research demonstrates that those feedbacks are also essential for the global carbon cycle—they help determine the net CO2 balance of the biosphere and have implications for improving critical management decisions in agriculture, security, climate change, and so much more.
Gentine and his team are now exploring ways to model how biosphere-atmosphere interactions may change with a shifting climate, as well as learning more about the drivers of photosynthesis, in order to better understand atmospheric variability.
Paul Dirmeyer, a professor in the department of atmospheric, oceanic and earth sciences at George Mason University who was not involved in the study, notes: "Green et al. The study is titled "Regionally strong feedbacks between the atmosphere and terrestrial biosphere. Naming priorities such as better land management, an evolved portfolio of 21st-century solutions and more funding for research and development, Stanford experts highlight areas central to success as the Biden-Harris administration aims its sights on safeguarding U.
Wildfire smoke will be one of the most widely felt health impacts of climate change throughout the country, but U. Stanford experts discuss the causes and impacts of wildfire activity and its rapid acceleration in the American west. Researchers examined the number of households unable to pay for damages from coastal flooding to reveal how sea-level rise could threaten the fabric of Bay Area communities over the next 40 years.
The findings, expertise and policy experience of Stanford researchers working across multiple fields could help contribute to sustainable, cost-effective solutions. Skip to content. Becoming part of Stanford's new school focused on climate and sustainability in Fall Lightning strikes in Yellowstone National Park in Wyoming.
Vegetation is a general term for the plant life of a region; it refers to the ground cover provided by plants, and is, by far, the most abundant biotic element of the biosphere. First, vegetation regulates the flow of numerous biogeochemical cycles, most critically those of water, carbon, and nitrogen; it is also of great importance in local and global energy balances. Such cycles are important not only for global patterns of vegetation but also for those of climate.
Second, vegetation strongly affects soil characteristics, including soil volume, chemistry and texture, which feed back to affect various vegetational characteristics, including productivity and structure. Third, vegetation serves as wildlife habitat and the energy source for the vast array of animal species on the planet and, ultimately, to those that feed on these.
Vegetation is also critically important to the world economy, particularly in the use of fossil fuels as an energy source, but also in the global production of food, wood, fuel and other materials.
Perhaps most importantly, global vegetation including algal communities has been the primary source of oxygen in the atmosphere, enabling the aerobic metabolism systems to evolve and persist. Lastly, vegetation is psychologically important to humans, who evolved in direct contact with, and dependence on, vegetation, for food, shelter, and medicines. Reference Terms. Vegetation serves several critical functions in the biosphere, at all possible spatial scales.
