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

Climate model shows large-scale wind and solar farms in the Sahara increase rain and vegetation
TLDR
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
TLDR
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
TLDR
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

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
