While the Amazon loses moisture, global warming could increase rainfall in the Sahara by up to 75% by the end of the century, changing the lives of billions.
Global warming is associated with profound changes in rainfall patterns, and the graph below depicts a striking contrast: while the Amazon rainforest may head towards extreme drought in the coming decades, the Sahara may move in the opposite direction, receiving significantly more precipitation.
According to researchers cited in the database, the Sahara, now one of the driest deserts in the world, could have… Up to 75% more rainfall by the end of the century.This would open the door to a broad environmental transformation, with social and economic impacts both inside and outside of Africa.
The stark contrast: a drier Amazon, a wetter Sahara.
The base depicts a world in apparent inversion: the Amazon, known for its humidity, could approach desert conditions in the coming decades, while the Sahara could become greener and wetter.
The idea is not that everything will change overnight, but that global warming will alter the way the atmosphere works and redistribute rainfall.
This contrast is important because it breaks the intuitive expectation that dry regions will always get drier and humid regions will always get wetter. What changes is the pattern….and this can shift risks and opportunities to different places.
Why the Sahara could receive up to 75% more rain
According to the database, researchers indicate that the Sahara could receive up to 75% more rain by the end of the century.
The text also mentions a key statistic: today, the desert receives around 8 cm of precipitation per year, which helps to illustrate how significant a percentage increase can be for the landscape and land use.
However, the database itself highlights an important limitation: the authors do not state the exact amount of rain that will fall in the coming years, only that precipitation is expected to increase. In other words, the trend is upward….but the exact magnitude is still uncertain.
The statement that sums up the problem: billions will be affected.
The report attributes the central message of the warning to the lead author, Thierry Ndetatsin Taguela: changes in rainfall patterns could affect billions of people, both inside and outside of Africa. This positions global warming not only as an environmental issue, but as a factor for public and private planning.
The highlighted recommendation is straightforward: it’s necessary to start planning how to deal with the changes, from flood control to cultivating drought-resistant plants. It’s not just about the weather.It’s about infrastructure, agriculture, health, housing, and food security.
Planning in practice: floods, agriculture and adaptation
When rainfall changes location and intensity, the impacts appear in a chain reaction. If there is increased precipitation in areas poorly prepared for larger volumes, the need for drainage and flood control grows.
At the same time, regions that become drier may need more resilient crops and more efficient water use strategies.
The basis reinforces this point by treating adaptation as something that needs to be thought about in advance and regionally. Climate planning is economic survival planning.because it affects production, transportation, prices, and social stability.
A key detail to consider is that the African continent does not exhibit a single pattern of behavior. The text points to different trends by region:
Southeastern Africa could see an increase in rainfall of around 25%.
South-central Africa could see an increase of around 17%.
The southwestern region of the continent could become drier, with an approximate 5% reduction in rainfall.
These differences matter because they show that global warming can create climate winners and losersdepending on the type of local economic activity, access to water, and adaptability.
If rainfall increases consistently, the Sahara could, as the study describes, move towards a greener and wetter landscape. This doesn’t automatically mean a ready-made forest, nor a simple transformation, but it indicates a possibility of landscape change and shifts in environmental dynamics.
It also means that risk management is shifting its focus: areas currently dominated by scarcity may have to deal with excess water at certain times, while areas that are currently wet may face water stress. It’s an exchange of challenges.Not an automatic happy ending.
The final warning: understanding the rain becomes a strategic issue.
The basis emphasizes that understanding how precipitation can change over the years is vital, because decisions need to be specific to each region. And this applies to governments, communities, and economic sectors alike.
Ultimately, global warming appears to be the driving force behind this climate reorganization. Even with uncertainties about exact figures, the direction indicated by the data is clear: rainfall patterns may change dramatically, requiring adaptation, investment, and planning.
In your opinion, which scenario is more worrying: a drier Amazon or a Sahara with much more rain and new risks of flooding?
