The rate of climate change surged alarmingly between 2011-2020, which was the warmest decade on record. Continued rising concentrations of greenhouse gases fuelled record land and ocean temperatures and turbo-charged a dramatic acceleration in ice melt and sea level rise. The Global Climate 2011-2020: A Decade of Acceleration report documents how extreme events across the decade had devastating impacts, particularly on food security, displacement and migration, hindering national development and progress toward the Sustainable Development Goals (SDGs). But it also showed how improvements in forecasts, early warnings and coordinated disaster management and response are making a difference. The number of casualties from extreme events has declined, associated with improved early warning systems, even though economic losses have increased.
