The impact of climate change and human activities on desertification are exemplified in the Sahel region of Africa. The region is characterized by a dry hot climate, high temperatures and low rainfall (100–600 mm per year). [44] So, droughts are the rule in the Sahel region. [45]
For instance, it might be difficult to tell if desertification or desert expansion is the result of climate change or human activity. [19] Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers.
The discussion about the impact of climate change on desertification focuses on drought. While some authors argue that periods of decline in the Levant were synchronous with reduced rainfall, others point to the non-linear development of settlement.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
These historical impacts of climate change can improve human life and cause societies to flourish, or can be instrumental in civilization's societal collapse. The study seeks to define periods in human history where temperature or precipitation varied from what is observed in the present day.
Climate change adaptation is the process of adjusting to the effects of climate change. These can be both current or expected impacts. [1] Adaptation aims to moderate or avoid harm for people, and is usually done alongside climate change mitigation. It also aims to exploit opportunities. Humans may also intervene to help adjust for natural ...
The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. [165] Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves.
