Even an increase in “natural disasters” can’t be used as an indicator without additional factors being considered.
Development and “flood defenses” in one place lead to flooding downstream. Plus, while we are seeing climate change, the question remains whether it is caused by our activities or is purely part of natural variation.
Since all this flooding is being caused by the melting polar ice caps, might I suggest a 100 megaton nuclear blast in no mans land up there to “evaporate” a portion of the cap?
No one up there anyway and as Hiroshima and Nagaski proved, the land will be habitable relatively quickly.
