Detailed explanation-1: -Climate change will more than double the risk of intense tropical cyclones by 2050. Human-caused climate change will make strong tropical cyclones twice as frequent by mid-century, putting large parts of the world at risk, according to a new study published in Scientific Advances.

Detailed explanation-2: -While there is not clear evidence that climate change is increasing or decreasing the frequency of these storms, there is strong evidence that increasing sea temperatures increase the intensity of tropical storms when they develop.

Detailed explanation-3: -As the air continues to warm due to climate change, hurricanes can hold more water vapor, producing more intense rainfall rates in a storm. Moreover, according to Knutson, most models show that climate change brings a slight increase in hurricane wind intensity.

Detailed explanation-4: -Global warming provides the atmosphere with more water vapour, giving storms more water to create heavier rainfall . It is projected by the IPCC that the intensity of tropical cyclones could likely increase if temperatures rise to 2 degrees Celsius .

Detailed explanation-5: -The Saffir-Simpson Hurricane Wind Scale consists of a five point scale of hurricane intensity and starts at 74 mph. Tropical cyclones with wind speeds up to 38 mph are classified as tropical depressions and those with wind speeds from 39-73 mph are classified as tropical storms.
