Climate change of Ghana is expected to become incredibly variable based on a 20 year baseline climate observation, it is forecasted that maize and other cereal crop yields will reduce by 7% by 2050. Available data also shows a sea level rise of 2.1 mm per year over the last 30 years, indicating a rise of 5.8 cm, 16.5 cm and 34.5 cm by 2020, 2050 and 2080.

Changes in rainfall, other extreme weather and sea level rise and salinity of coastal waters, is expected to negatively affect food security, in both farming and in fisheries. The national economy stands to suffer from the impacts of climate change because it is dependent on climate sensitive-sectors such as agriculture, energy, forestry, etc. Moreover, access to freshwater is expected to create challenges for both sanitary water, and hydropower which provides 54% of the country's electric capacity. Additionally, Ghana will likely see certain diseases, like malaria and cholera exacerbated by changing weather conditions.

In summary, climate change in Ghana is projected to affect its vital water resources, energy supplies, crop production and food security. With its three northern regions the most vulnerable, Ghana is already experiencing increased extreme weather conditions with higher incidences and more prolonged periods of flooding and droughts hence high temperatures will further increase, and rainfall patterns are less predictable now. More intense rainfall is expected to increase erosion, while less total rainfall may decrease the water flow. The country’s vulnerability is largely due to dependence on the production of crops that are sensitive to climate change, including cassava and cocoa, and by a lack of agricultural diversification.
