A less dusty future?
[1] Atmospheric desert dust is potentially highly sensitive to changes in climate, carbon dioxide and human land use. In this study we use 6 different scenarios of the processes responsible for changes in source areas and explore changes in desert dust loading in pre-industrial and future climates, although all the scenario results are likely to be sensitive to the climate model simulations use...
متن کاملA less or more dusty future in the Northern Qinghai-Tibetan Plateau?
Dust plays an important role in climate changes as it can alter atmospheric circulation, and global biogeochemical and hydrologic cycling. Many studies have investigated the relationship between dust and temperature in an attempt to predict whether global warming in coming decades to centuries can result in a less or more dusty future. However, dust and temperature changes have rarely been simu...
متن کاملAtmospheric carbon dioxide in a less dusty world
[1] The availability of iron exerts a significant control on primary production and the export of organic matter over large areas of the ocean, especially those far from land sources. We explore the regulation of the global soft tissue pump of carbon and atmospheric CO2 by the atmospheric delivery of iron in a three-dimensional ocean circulation and biogeochemistry model. There is only a small ...
متن کاملReligious people discount the future less
The propensity for religious belief and behavior is a universal feature of human societies, but religious practice often imposes substantial costs upon its practitioners. This suggests that during human cultural evolution, the costs associated with religiosity might have been traded off for psychological or social benefits that redounded to fitness on average. One possible benefit of religious ...
متن کاملA Clearer View of a Dusty Sky
The theory of inflation hypothesizes that the Universe underwent a period of rapid expansion less than 10−32 seconds after its birth [1]. If inflation occurred, physicists believe it would have produced large-scale gravitational waves, imprinting a slight swirl-like polarization—known as B modes—on the cosmic microwave background (CMB), the light generated when the Universe was 380,000 years ol...
