– Heat trapped by fossil fuel emissions is causing Earth's atmosphere to become more intense
– Researchers propose adding a more extreme category to the Saffir-Simpson Hurricane Wind Scale, Category 6
– The current scale is inadequate and does not capture the extent of hurricane damage
– Climate change increases temperature and moisture, leading to an increase in wind speed
– Category 6 storms would encompass hurricanes with winds racing at nearly 310 kph (192 mph) or more
– At least five storms since 1980 would fall into that category, and all of them have occurred in the last 9 year
– Adding a sixth category could raise awareness about the perils of major TCs due to global warming.
