One mechanism for climate change is the collected impact of changes in land cover or land use. Such changes are especially significant in urban areas where much of the world’s population lives. Satellite observations provide a basis for characterizing the physical modifications that result from urbanization. In particular, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on ...

Intraspecific variation in crop responses to global climate change conditions would provide opportunities to adapt crops to future climates. These experiments explored intraspecific variation in response to elevated CO₂ and to high temperature during anthesis in Chenopodium quinoa Wild. Three cultivars of quinoa were grown to maturity at 400 ("ambient") and 600 ("elevated") μmol·mol-1 CO₂ conce...

BACKGROUND Global climate change is anticipated to reduce future cereal yields and threaten food security, thus potentially increasing the risk of undernutrition. The causation of undernutrition is complex, and there is a need to develop models that better quantify the potential impacts of climate change on population health. OBJECTIVES We developed a model for estimating future undernutritio...

[1] Simulations of potential vegetation distribution, natural fire frequency, carbon pools, and fluxes are presented for two DGVMs (Dynamic Global Vegetation Models) from the second phase of the Vegetation/Ecosystem Modeling and Analysis Project. Results link vegetation dynamics to biogeochemical cycling for the conterminous United States. Two climate change scenarios were used: a moderately wa...

Recent projections of global climate changes in response to increasing greenhousegas concentrations in the atmosphere include warming in the Southwestern US and, especially, in the vicinity of Lake Tahoe of from about +3°C to +6°C by end of century and changes in precipitation on the order of 5–10% increases or (more commonly) decreases, depending on the climate model considered. Along with the...

The study examined the food security status and the socioeconomic effects of climate change on rural farming households in Delta State, Nigeria. The main objective of the study was to determine the food security status of the rural farming households in the state while the specific objective was to determine the socio-economic effects of climate change on rural farming households in the state. ...

[1] The fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) includes a comparison of observation-based and modeling-based estimates of the aerosol direct radiative forcing. In this comparison, satellite-based studies suggest a more negative aerosol direct radiative forcing than modeling studies. A previous satellitebased study, part of the IPCC comparison, uses aero...

Industrialization and increasing demand for the consumption of fossil fuels cause that energy becomes a strategic factor. Energy crisis and the emergence of modern architecture led designers to pay more attention to the important task of building's envelope. Building skins play an important role in building thermal behavior and reduce energy consumption. If Double Skin Facades properly designed...
