Far future (100's-1000's of years), optimistic. Floods, a.k.a. fat-tail disasters like civilization collapse, have happened numerous times in the past, they'll happen numerous more times going forward, we'll continue to be around. We won't go to the stone age, but we'll lose a lot of modern comforts. Near future, pessimistic. A bad flu completely disrupted our global little village - imagine what actual unprecedented natural disasters and abrupt resource shortages will do. When hundreds of millions of people have the rug pulled out from under them with no local sustainable fallbacks, it's going to get very ugly.
