Large‐scale photovoltaic solar farms envisioned over the Sahara desert can meet the world's energy demand while increasing regional rainfall and vegetation cover. However, adverse remote effects resulting from atmospheric teleconnections could offset such regional benefits. We use state‐of‐the‐art Earth‐system model simulations to evaluate the global impacts of Sahara solar farms. Our results indicate a redistribution of precipitation causing Amazon droughts and forest degradation, and global… 
Direct impact of solar farm deployment on surface longwave radiation
Motivated by a previous study of using the Moderate Resolution Imaging Spectroradiometers (MODIS) observations to quantify changes in surface shortwave spectral reflectances caused by six solar farms
Optimization of weather forecasting for cloud cover over the European domain using the meteorological component of the Ensemble for Stochastic Integration of Atmospheric Simulations version 1.0
. In this study, we present an expansive sensitivity analysis of physics configurations for cloud cover using the Weather Forecasting and Research Model (WRF V3.7.1) on the European domain. The
Review of Photovoltaic Power and Aquaculture in Desert
This paper investigates the solar power and aquaculture industry in the desert and explains the limitations and challenges, and hopes to increase interest and help with future research.
Full Cost of Electricity “FCOE” and Energy Returns “eROI”
Understanding electricity generation’s true cost is paramount to choosing and prioritizing our future energy systems. This paper introduces the full cost of electricity (FCOE) and discusses energy


Climate model shows large-scale wind and solar farms in the Sahara increase rain and vegetation
A climate model with dynamic vegetation is used to show that large-scale installations of wind and solar farms covering the Sahara lead to a local temperature increase and more than a twofold precipitation increase, especially in the Sahel, through increased surface friction and reduced albedo.
Tropical cyclone activity enhanced by Sahara greening and reduced dust emissions during the African Humid Period
This modeling study shows the crucial role of vegetation cover over the Sahara and reduced dust emission in altering tropical cyclone activity during the mid-Holocene (6,000 yBP) and suggests that both factors may have appreciable influence on TC activity in a future warmer climate.
Dynamic Vegetation Simulations of the Mid‐Holocene Green Sahara
The “Green Sahara” is a period when North Africa was characterized by vegetation cover and wetlands. To qualitatively identify the orbital‐climatic causation of the Green Sahara regime, we performed
Rainfall regimes of the Green Sahara
Evidence for a prolonged “pause” in Green Sahara conditions 8000 years ago is found, coincident with a temporary abandonment of occupational sites by Neolithic humans and climate models systematically fail to reproduce the Green Sahara.
Remote Vegetation Feedbacks and the Mid-Holocene Green Sahara
AbstractIn the mid-Holocene, the climate of northern Africa was characterized by wetter conditions than present, as evidenced by higher paleolake levels and pollen assemblages of savannah vegetation
Dryland climate change: Recent progress and challenges
Drylands are home to more than 38% of the world's population and are one of the most sensitive areas to climate change and human activities. This review describes recent progress in dryland climate
Holocene changes in African vegetation: tradeoff between climate and water availability
Abstract. Although past climate change is well documented in West Africa through instrumental records, modeling activities, and paleo-data, little is known about regional-scale ecosystem
Arctic climate response to the termination of the African Humid Period
Forest response to rising CO2 drives zonally asymmetric rainfall change over tropical land
Understanding how anthropogenic CO2 emissions will influence future precipitation is critical for sustainably managing ecosystems, particularly for drought-sensitive tropical forests. Although
