Feb 2, 2021 · Studies have reported an upward trend in annual rainfall in the Sahel since the 1970s and 1980s, when the region experienced a profound drought with over a 30% decrease in rainfall. However, farmers have questioned whether this increase has improved vegetation and crop conditions.
The Sahel remains one of the poorest and least developed regions in the world. It’s also one of the most vulnerable to climate change and variability. One bright spot for the region is that since the mid-1980s, average rainfall has increased steadily [see this animation ].
Jun 27, 2016 · Simulating Sahel rainfall in a climate model, the researchers find that the principal cause is human-caused warming of the Mediterranean Sea. Moisture supply. So, how does a warmer Costa del Sol trigger rainfall over several thousand kilometres away in Africa?
Jun 27, 2016 · The Sahel has suffered through severe droughts but recent years have seen increased rainfall. Now research suggests warming of the Mediterranean Sea surface may dictate future rainfall in the...
Since the mid-1980s, average rainfall in the Sahel has partially recovered, possibly contributing in places to a ‘re-greening’ of vegetation so widespread that it can be observed from space. Recently, a paper published in Nature Climate Change argued that climate change from rising greenhouse-gas emissions can explain most of the increase.
New computer simulations show a significant future increase in seasonal rainfall in the Sahel under the current trend of global warming. A major increase in average rainfall might kick-in by 2040 already, which means that it is inevitable regardless of how future greenhouse gas emissions develop.
Jul 5, 2017 · Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability.
