Is Global warming a serious problem in Japan?

In Japan, I couldn’t feel global warming seriously. However, sometimes there is some extraordinary weather in Japan, but I don’t know how extraordinary weather relates to global warming. For example, especially in summer, weather has become similar to tropical weather. We often get like a squall same as the tropics. Some of Japanese meteorologists refer that Japan will become the tropics in the future because of global warming. Actually, I can’t believe right now. However we should consider about it. Next, nowadays flood has been increasingly in Japan. I often can watch them on TV news. If heavy rain occurred, it will be flood easily, recently. Also, deforestation is a big problem to occur flood. Anyway, a convulsion of nature often is occurred on the earth. It might indicate global warming and crisis of the earth. We have to tackle about environmental problems and take actions from each of us. At no distant date, we would face crisis of the earth. For it, we have to take care of the planet.
