Heavy rain is just one part of climate change. In fact, where I live, there is usually no rain and high humidity like this year. It rains all week in January which is rare, in addition the wind is very strong. Rain also damages agricultural products and food crops, leading to higher prices. I think it is an element that has a significant influence on economic development.
Excess of everything is bad whether its continuous rain or drought. For last one year in my country there are unusual rains along with hailstorm and due to this crop production has significantly gone down. Its may and in May we have heat at it's peak but due to unusual rains fans of off. There are floods coming in winter also due to these rains. There is urgent need of measures to stop global warming.
