You are right, abandon and retreat to high ground, except as one person interviewed on TV said, "who would buy my house, it is in a flood zone?". I believe that there are many in Houston, and elsewhere in Texas, at risk, and without the financial resources to move elsewhere. In reality, we are seeing the beginning of what may become the great migration within the US, from at risk flood and coastal areas to higher ground. We will have never seen a migration such as this, and we probably cannot even imagine it. Irregardless of what the climate change deniers such as Gov. Rick Perry (Texas) believes or wants us to believe, the waters are rising, the heat is heating, and doing nothing about it is a no-win situation. If you stay in the at-risk location you are going to die sooner rather than later. This all means new cities, new communities, new businesses and new opportunities, but if the leadership continues to chant the same-old false hoods, the people will be delayed in their move.
