Scientists want a new category to measure hurricanes. They want to add a category 6 to the current 1 to 5 scale. A category 5 measures winds of up to 252 kph. A new category is for winds of over 309 kph. In the past 10 years, there have been five hurricanes that would be a category 6.

A scientist wants more discussions about the risks in a warming world. Greenhouse gasses are heating oceans. This gives the water extra energy. This makes hurricanes more powerful. Wind speeds are much higher. The scientist said: "These storms keep getting stronger as the climate changes."
