Many subtropical regions are expected to become drier due to climate change. This will lead to reduced vegetation which may in turn amplify the initial drying. Using a coupled atmosphere‐ocean‐land model with a dynamic vegetation component that predicts surface albedo change, here we simulate the climate change from 1901 to 2099 with CO2 and other forcings. In a standard IPCC‐style simulation, the model simulated an increase in the world's ‘warm desert’ area of 2.5 million km2 or 10% at the end… 
The observed cooling effect of desert blooms based on high‐resolution Moderate Resolution Imaging Spectroradiometer products
Desert greening through planting or irrigation is a potential approach to mitigate desertification and climate warming, but its influence on regional climate is unclear due to scarcity of
Sensitivity of natural vegetation to climate change in the Euro-Mediterranean area
This study explores the sensitivity to future climate change of natural vegetation patterns in the Euro-Mediterranean area under the IPCC-A1B emission scenario, using a dynamic vegetation model
Vegetation feedback under future global warming
It has been well documented that vegetation plays an important role in the climate system. However, vegetation is typically kept constant when climate models are used to project anthropogenic climate
Relationship between the expansion of drylands and the intensification of Hadley circulation during the late twentieth century
The changes in coverage by arid climate and intensity of the Hadley circulation during the second half of the twentieth century were examined using observations and the multi-model ensemble (MME)
Will Amazonia Dry Out? Magnitude and Causes of Change from IPCC Climate Model Projections
AbstractThe Amazon rain forest may undergo significant change in response to future climate change. To determine the likelihood and causes of such changes, the authors analyzed the output of 24
Climatic and ecological future of the Amazon: likelihood and causes of change
Abstract. Some recent climate modeling results suggested a possible dieback of the Amazon rainforest under future climate change, a prediction that raised considerable interest as well as
Sensitivity of arid/humid patterns in China to future climate change under a high-emissions scenario
Changes in regional moisture patterns under the impact of climate change are an important focus for science. Based on the five global climate models (GCMs) participating in the Coupled Model
Regional feedbacks under changing climate and land-use conditions
Abstract. Ecosystem responses to a changing climate and human-induced climate forcings (e.g. deforestation) might amplify (positive feedback) or dampen (negative feedback) the initial climate
Are the North American deserts expanding? Some climate signals from groundwater storage conditions
The areal average underground water storage in a natural catchment is directly manifested by the low flow or baseflow features from that catchment. Accordingly, an analysis was conducted of the

Enhanced albedo feedback in North Africa from possible combined vegetation and soil-formation processes
It has long been recognized that albedo related vegetation feedbacks amplify climate variability in North Africa. Recent studies have revealed that areas of very high albedo associated with certain

It is suggested that the high albedo of a desert contributes to a net radiative heat loss relative to its surroundings and that the resultant horizontal temperature gradients induce a frictionally

Changes in desert area due to humans have important implications from a local, regional to global level. Here I focus on the latter in order to better understand estimated changes in desert dust

Vegetation is known to interact with the other components of the climate system over a wide range of timescales. Some of these interactions are now being taken into account in models for climate
Model Projections of an Imminent Transition to a More Arid Climate in Southwestern North America
TLDR
There is a broad consensus among climate models that this region will dry in the 21st century and that the transition to a more arid climate should already be under way, and the levels of aridity of the recent multiyear drought or the Dust Bowl and the 1950s droughts will become the new climatology of the American Southwest within a time frame of years to decades.
