Barack Obama, who served as president of the United States from 2009 to 2017, believes that the global community is doing far less to combat climate change than necessary.
Mr Obama, oo Aqalaka Cad ka arriminayay intii u dhaxeysay sannadadii 2009-kii ilaa iyo 2017-kii ayaa sheegay in dalka uusan u baahanayn isbedel weyn balse uu u baahan yahay hormarinada ay shacabka daneeynayaan.
