Human-caused climate change made Atlantic hurricanes about 18mph stronger in the last six years, a study shows.

For most of the storms – 40 of them – the extra push from warmer oceans made the storms jump an entire hurricane category, according to the study published in the journal, Environmental Research: Climate.
