==== Climate change ====
A 2019 paper published in [[PLOS One]] estimated that under [[Representative Concentration Pathway#4.5|Representative Concentration Pathway 4.5]], a "moderate" scenario of [[climate change]] where global warming reaches ~{{convert|2.5-3|C-change|F-change}} by 2100, the climate of Luanda in the year 2050 would most closely resemble the current climate of [[Guatemala City]]. The annual temperature would increase by {{convert|0.7|C-change|F-change}}, the temperature of the coldest month by {{convert|0.4|C-change|F-change}}, and the temperature of the warmest month by {{convert|0.1|C-change|F-change}}.<ref>{{cite journal |last1=Bastin |first1=Jean-Francois |last2=Clark |first2=Emily |last3=Elliott |first3=Thomas |last4=Hart |first4=Simon |last5=van den Hoogen |first5=Johan |last6=Hordijk |first6=Iris |last7=Ma |first7=Haozhi |last8=Majumder |first8=Sabiha |last9=Manoli |first9=Gabriele |last10=Maschler |first10=Julia |last11=Mo |first11=Lidong |last12=Routh |first12=Devin |last13=Yu |first13=Kailiang |last14=Zohner |first14=Constantin M. |last15=Thomas W. |first15=Crowther |title=Understanding climate change from a global analysis of city analogues |journal=PLOS ONE |date=10 July 2019 |volume=14 |issue=7 |at=S2 Table.

Moreover, according to the 2022 [[IPCC Sixth Assessment Report]], Luanda is one of 12 major African cities ([[Abidjan]], [[Alexandria]], [[Algiers]], [[Cape Town]], [[Casablanca]], [[Dakar]], [[Dar es Salaam]], [[Durban]], [[Lagos]], [[Lomé]], Luanda and [[Maputo]]) which would be the most severely affected by the future [[sea level rise]]. It estimates that they would collectively sustain cumulative damages of USD 65 billion under RCP 4.5 and USD 86.5 billion for the high-emission scenario RCP 8.5 by the year 2050. Additionally, RCP 8.5 combined with the hypothetical impact from [[marine ice sheet instability]] at high levels of warming would involve up to 137.5 billion USD in damages, while the additional accounting for the "low-probability, high-damage events" may increase aggregate risks to USD 187 billion for the "moderate" RCP4.5, USD 206 billion for RCP8.5 and USD 397 billion under the high-end ice sheet instability scenario.<ref>Trisos, C.H., I.O.
