Mozambique: Global 2º Compared to 1.5º for Mozambique - Hotter, Drier, Worse Cyclones; South Hit Hardest

IEA cites extensively a report by the IPCC (Intergovernmental Panel on Climate Change), which is so detailed that it is possible to estimate the difference between global warming of 1.5º and 2º for Mozambique. The 1.5º and 2º are global average increases, and the actual impacts vary significantly across the world, and even within Mozambique.

+ Temperature rise in Mozambique will be more serious at global 2º than global 1.5º of warming. The hottest days and coldest nights will both be hotter. Global 1.5º causes a Mozambique temperature rise, but the increase is much greater at 2º. The number of hot days increases more in the north than in the south.

+ Southern Mozambique will become much dryer at 2º with droughts. Water shortages will be more severe at 2º than 1.5º. The number of consecutive dry days increases, particularly in the south.

+ Total rainfall will decrease more at 2º than 1.5º across Mozambique, and will be most serious south of the Zambeze river. However extreme rainfall increases significantly, particularly in northern coastal zones.

+ The number of cyclones may actually decrease, but their intensity increases. Thus flooding causes by heavy rain and intense cyclones will be more serious with 2º warming than with 1.5º.

+ The ocean will get warmer, and sea level will rise - with significant difference between 1.5º and 2º.

+ There is increased risk to mangroves.

+ Moving from 1.5° to 2° of warming reduces maize yield and the suitability of maize as a food crop. Food shortages are predicted, and the risks at 2º are "much larger than the corresponding risks at 1.5°".

This all comes from an extremely detailed comparison of 1.5º and 2º with maps good enough to identify differences within Mozambique in Chapter 3 of the IPCC (Intergovernmental Panel on Climate Change) thick 2018 tome Global warming of 1.5ºC .
