Is global warming is real?

Global warming is real. The islands that get submerged and the ice that melts in the polar zone are real. I think we need to check greenhouse effect in control. If we don't do that some coutries will really suffer. For example, Bangladesh which hardly pollutes the air compared to some countries will be hit hard. And it actually is not just because due to some other countries' uncheck of pollution emission this country is really going to suffer.
