RT @UN_PGA: Today, we mark 20 years since the 2004 Indian Ocean Tsunami, which was the first global disaster of the 21st century and one of the most devastating disasters in recent history. We must reaffirm our collective resolve to prepare and protect future generations from the impacts of such natural disasters by incorporating disaster risk reduction and resilience into our sustainable development strategies. #Tsunami #Tsunami2004 @UNDRR @UNDRR_AsiaPac UNDRR Climate Change Science on Telegram by @ClimateChangeScience A @grttme project - Other backups: @Hallotme
