Climate change is influencing weather patterns to increase the strength of tornadoes. A professor at Florida State University, James Eisner, has linked climate change to tornado strength, which scientists never believedbefore. Eisner has claimed that alterations in the level of moisture and heat content present in the atmosphere are causing changes in tornado patterns.

The National Weather Service Storm Prediction Center has recorded 189 storms in the US this year, claiming lives of 43 people. The deaths happened despite the warning systems in place in storm prone areas. The US is known to experience more tornadoes than other countries with increasing tornado strength.

A new study, co-authored by a geography professor at Florida State University, has claimed that more severe tornadoes are likely to be witnessed in the US because of climate change. "I think it's important for forecasters and the public to know this. It's a matter of making sure the public is aware that if there is a higher risk of a storm, there may actually be multiple storms in a day", said Eisner.

Elsner has previously studied the relationship between climate change and hurricanes and now he has come up with a new research, showing a link between climate change and tornadoes.

President Barack Obama's administration and environmental groups also blamed global warming for Hurricane Sandy, which occurred in 2012.
