A new study finds that climate change and El Niño combined to rev up last month's explosively intensifying Hurricane Polo, which was the longest-lasting Category 5 storm ever to churn in the Pacific.
Global warming caused by the burning of coal, oil and gas was the bigger of the two culprits, adding nearly 10 kph to its already monstrous strength, according to a joint study published on 14 October by scientists from World Weather Attribution and Climate Central. El Niño contributed a bit less, about 8 kph, a study co-author said.
