Global warming is mostly the effect of all the human activity that is slowly making the temperatures increase over the years. Like how in the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution. It produces about two billion tons of CO2 every year. Coal-burning power plants are the biggest polluters(because coal is so rich in carbon.) The country’s second-largest source of carbon pollution is the transportation part. The transportation part generates about 1.7 billion tons of CO2 emissions a year. The temperatures have increased about 32°F (according to the NASA website below.)
On the other hand, when there is a thunderstorm, tornadoes happen when you have warm/moist air that competes with cool dry air. When they meet they create an unstable part in the atmosphere making a horizontal spinning effect in the lower part of the atmosphere. An increase in wind direction and an increase in speed tilts the rotation upwards into the thunderstorm. The funnel cloud collects particles from the storm. Once it touches the ground it will destroy almost everything in its path (depending on the power of the tornado, They rank from EF-0 to EF-5.)
Erratic weather does seem to accompany climate change, which would make sense. Tornadoes typically don't occur in cold weather. With global warming, we are seeing warmer weather trends and more unstable atmospheres, which lend to the formation of weather events such as tornadoes. I'm not surprised to see an increase in these weather occurrences.
The unprecedented wintertime tornado outbreak is most likely a result of climate change. Yes, there have always been tornadoes that occur during all times of the year. However, it is extremely rare to experience a multi-day tornado outbreak which results in 40 tornadoes, during the winter. As our climate continues to change, the amount of severe storms will increase.
This is possible. Tornadoes may actually increase due to the global warming. This global warming is occurring due to the human activities. We humans should regulate such activities that lead to global warming which affect the ozone layer and lead to the calamities such as tornadoes. If this is not done, then the tornadoes will increase.
There is no way that global warming produces tornadoes. An increase in heat alone doesn't cause tornadoes to just happen. Instead, there have to be specific storms in the atmosphere that cause the right conditions to develop. Global warming is not significant yet, and it's a stretch to blame it on tornadoes.
