Tornadoes are ranked by the severity of the damage they cause, which is used to estimate wind speed. Each number represents a different level of damage. Here are the categories with wind speed estimates and typical damage.
EF0: 65-85 mph. Shingles and siding peeled from homes, tree limbs broken. Some trees uprooted or snapped.
EF1: 86-110 mph. Roofs of homes badly damaged. Windows broken. Mobile homes overturned or seriously damaged.
EF2: 111-135 mph. Roofs torn from well built houses. Mobile homes completely destroyed. Large trees snapped.
EF3: 136-165 mph: Roofs and multiple walls torn from well built houses. Most weaker structures completely destroyed.
EF4: 166-200 mph: Well built houses completely leveled. Trees debarked. Asphalt peeled from some roads.
EF5: over 200 mph. Very well built houses wiped clean off foundations. Cars tossed upwards of 600 feet (200 meters). Ground surface scoured away in some locations.

Is the climate change causing more tornadoes?
No. There has not been an increase in the number of tornadoes. In fact, in the past 70 years the number of strong tornadoes in the US has generally decreased. Improvements in technology mean that tornadoes are more likely to be reported when they do occur, resulting in a seeming increase. Scientists are still unsure how climate change will affect tornado activity.
