In 2017, hurricanes wreaked havoc from the Caribbean to Ireland. More than 1,200 people have died in flooding across India, Bangladesh and Nepal. Drought affected East Africa and the western United States. Prolonged dry conditions in southern Europe led to water shortages and wildfires.
Europe in 2017 was generally warmer than the long-term average, particularly in the far north. Sea-ice cover was notably below average. December was particularly warm in eastern Europe, with lower than average temperatures in the southwest.
