Global atmospheric changes.
Increasing concentrations of CO2 and other greenhouse gases in the atmosphere can be directly related to global warming. In terms of human health, because a major cause of increasing atmospheric concentrations of CO2 is the increased combustion of fossil fuels, global warming also may result in increases in air pollutants, acid deposition, and exposure to ultraviolet (UV) radiation. To understa...
متن کاملGlobal atmospheric methane: budget, changes and dangers.
A factor of 2.5 increase in the global abundance of atmospheric methane (CH(4)) since 1750 contributes 0.5 Wm(-2) to total direct radiative forcing by long-lived greenhouse gases (2.77 Wm(-2) in 2009), while its role in atmospheric chemistry adds another approximately 0.2 Wm(-2) of indirect forcing. Since CH(4) has a relatively short lifetime and it is very close to a steady state, reductions i...
متن کاملResponse of global soil consumption of atmospheric methane to changes in atmospheric climate and nitrogen deposition
[1] Soil consumption of atmospheric methane plays an important secondary role in regulating the atmospheric CH4 budget, next to the dominant loss mechanism involving reaction with the hydroxyl radical (OH). Here we used a process-based biogeochemistry model to quantify soil consumption during the 20th and 21st centuries. We estimated that global soils consumed 32–36 Tg CH4 yr 1 during the 1990s...
متن کاملForecasting global atmospheric CO2
A new global atmospheric carbon dioxide (CO2) real-time forecast is now available as part of the preoperational Monitoring of Atmospheric Composition and Climate – Interim Implementation (MACC-II) service using the infrastructure of the European Centre for MediumRange Weather Forecasts (ECMWF) Integrated Forecasting System (IFS). One of the strengths of the CO2 forecasting system is that the la...
متن کاملGlobal Atmospheric Monitoring with SCIAMACHY
SCIAMACHY (Scanning Imaging Absorption spectroMeter for Atmospheric CHartographY) is a space based spectrometer designed to measure sunlight transmitted, reflected and scattered by the Earth atmosphere or surface. It is a contribution to the Envisat-1 satellite to be launched in late 1999. SCIAMACHY measurements will provide amounts and distribution of Os, BrO, OClO, ClO, SOz, H&O, NOa, CO, COs...
