Global warming or less lightning?

A new British study shows that some familiar natural scenes, such as thunder and lightning, may increase in the future due to global warming.
Lightning is a discharge scene accompanied by lightning and thunder. Lightning usually occurs in cumulonimbus clouds with vigorous convection, and is often accompanied by fierce gusts and rainstorms. There are often ice crystals in the upper part of the cloud. The changes of ice crystals and water droplets, as well as air convection and other processes, cause electric charges in the cloud.
The research team led by scholars from the University of Leeds in the UK announced in the UK’s Nature Climate Change magazine that they had calculated the impact of continued global warming on the atmospheric environmental elements that constitute thunder and lightning. The consequence shows that if the global temperature rises by about 5 ℃ by 2100, the number of uniform thunder and lightning will increase by 15%.
Declan Finney, the secondary author of the report and a scholar at Leeds University, said that the composition and movement of ice crystals in the cloud would be greatly affected by the downward trend of the temperature rise, which would eventually lead to an increase in the number of thunder and lightning.
However, some superstitions hold the same idea. A study announced by American researchers in 2014 said that global warming could lead to more thunderstorms and extreme weather, believing that lightning would increase by 12% for every 1 ℃ rise in global temperature
