Greenhouse Gas Molecules: A Mathematical Perspective
Introduction Climate change and global warming have drawn worldwide attention in the new century. Concern about possible global warming and the controversy over the claim that it is mainly caused by the greenhouse effect provide motivation for better understanding the mathematics, physics, and chemistry of greenhouse gases. The molecules of these gases trap heat in the form of infrared radiatio...
متن کاملWildland fire emissions, carbon, and climate: Plume rise, atmospheric transport, and chemistry processes
This paper provides an overview and summary of the current state of knowledge regarding critical atmospheric processes that affect the distribution and concentrations of greenhouse gases and aerosols emitted from wildland fires or produced through subsequent chemical reactions in the atmosphere. These critical atmospheric processes include the dynamics of plume rise, chemical reactions involvin...
متن کاملThe Costs of Reducing Greenhouse-Gas Emissions
Human activities around the world are producing increasingly large quantities of greenhouse gases, particularly carbon dioxide (CO2) resulting from the consumption of fossil fuels and deforestation. Most experts expect that the accumulation of such gases in the atmosphere will result in a variety of environmental changes over time, including a gradual warming of the global climate, extensive ch...
متن کاملModeling modern methane emissions from wetlands 1980-present
Methane is one of the important greenhouse gases and plays an important role in atmospheric chemistry. Its contribution to the current greenhouse effect is about 22%. Since the beginning of the industrialization the atmospheric methane concentration has increased by a factor of 2.5. This increase continues until present, however, since the early 1990s the growth rate has decreased. Superimposed...
متن کاملProduction, Isotopic Composition, and Atmospheric Fate of Biologically Produced Nitrous Oxide
■ Abstract The anthropogenic production of greenhouse gases and their consequent effects on global climate have garnered international attention for years. A remaining challenge facing scientists is to unambiguously quantify both sources and sinks of targeted gases. Microbiological metabolism accounts for the largest source of nitrous oxide (N2O), mostly due to global conversion of land for agr...
