The exact attribution of climate change to the occurrence of droughts and floods in Ethiopia is difficult. One study from 2022 stated for Ethiopia: "While regional models predict increase in rainfall, higher resolution analyses for Ethiopia suggest spatial variations in which there are both increases and decreases in the overall rainfall averages.
Climate change is of great concern in Ethiopia, especially since the 1970s. Between the mid-1970s and late 2000s, Ethiopia's rainfall in some areas and seasons decreased by 15-20 percent. Furthermore, numerous studies predict climate change will increasingly affect the country's ecosystem, causing drought and famines.
Köppen climate classification of climate of Ethiopia. The seasons of Ethiopia consist of four phases: Tsedey (Amharic: ጸደይ, Oromo: Arfaasaa, equivalent to spring) lasting from September to November, Bega (Amharic: በጋ, Oromo: Ganna, equivalent to summer) from December to February, Belg (Amharic: በልግ) (Oromo: Birraa, equivalent to Fall) from March to May and Kiremt (Amharic ...
Climate changes of 535-536 (535–536 AD), sudden cooling and failure of harvests, perhaps caused by volcanic dust; 900–1300 Medieval Warm Period, wet in Europe, arid in North America, may have depopulated the Great Plains of North America, associated with the Medieval renaissances in Europe Great Famine of 1315–1317 in Europe
Climate change will accelerate the prevalence of pests and diseases and increase the occurrence of highly impactful events. [195] The impacts of climate change on agricultural production in Africa will have serious implications for food security and livelihoods. Between 2014 and 2018, Africa had the highest levels of food insecurity in the ...
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 ...

Furthermore, climate change may disrupt the ecology among interacting species, via changes on behaviour and phenology, or via climate niche mismatch. [9] The disruption of species-species associations is a potential consequence of climate-driven movements of each individual species in opposite directions.
