Climate alarmists are telling us the world is coming to an end and we are the cause. Is this true?

The fact that over the last 80 years Northern Delaware has gone from being very rural to very urban. There has been urban street flooding, which leads to flooding of the rivers and streams. More people demanding water. So, when we get low on water resources, droughts are much more frequent. So, we are seeing more floods and droughts, it has nothing to do with climate change. And in fact, in most of the variables, there are no major changes connected to carbon dioxide. Carbon dioxide seems to be only a minor player in climate change.
