Rapport spécial du GIEC sur les océans et la cryosphère dans le contexte du changement climatique Quels impacts pour l’Afrique ?

The document details how human-induced climate change is altering ocean chemistry and temperature, leading to acidification, oxygen loss, and rising sea levels that threaten African coastal communities and marine biodiversity. It highlights the melting of high-mountain glaciers in East Africa, affecting water security and increasing landslide risks. The guide emphasizes that urgent greenhouse gas emission reductions are the primary way to limit these damages, while early investment in disaster risk reduction and nature-based solutions, such as 'blue carbon' ecosystems, can reduce future costs and enhance resilience.

• Human activity has caused global average temperatures to rise by 1°C above pre-industrial levels, with projections reaching between 1.6°C and 4.3°C by 2100 depending on emission reductions.
• The oceans have absorbed over 90% of the climate system's excess heat and 20% to 30% of human-produced carbon dioxide emissions since the 1980s, resulting in increased acidification and a decrease in dissolved oxygen between 1970 and 2010.
