GENEVA — The head of the UN weather agency blamed human-induced climate change for extreme weather Monday, citing key events that caused havoc in Asia, Europe, the United States, and Pacific region last year. Michel Jarraud, secretary-general of the World Meteorological Organization, said his agency’s annual assessment of the global climate shows how dramatically people and lands everywhere felt the impacts of extreme weather such as droughts, heat waves, floods, and tropical cyclones.
‘‘Many of the extreme events of 2013 were consistent with what we would expect as a result of human-induced climate change,’’ he said.
The UN agency called 2013 the sixth-warmest year on record. Thirteen of the 14 warmest years have occurred in the 21st century.
A rise in sea levels is leading to increasing damage from storm surges and coastal flooding, as demonstrated by Typhoon Haiyan, Jarraud said. The typhoon in November killed at least 6,100 people and caused $13 billion in damage to the Philippines and Vietnam.
Australia had its hottest year on record and parts of central Asia and central Africa also notched record highs. Jarraud drew special attention to studies and climate modeling examining Australia’s recent heat waves, saying the high temperatures there would have been virtually impossible without the emissions of heat-trapping carbon dioxide from the burning of coal, oil, and gas.
He cited other costly weather disasters such as $22 billion damage from central European flooding in June, $10 billion in damage from Typhoon Fitow in China and Japan, and a $10 billion drought in much of China.
