Patriotic Songs and Global Warming

Recently I got to thinking how, due to global warming, America might need to change the words to some of our patriotic songs. Here's an example. In 1904 Katharine L. Bates penned the words to "O Beautiful for Spacious Skies". Below, with changed words in brackets, please find my opinion of how we will have to sing it in the future, if we take into the account the new reality of global warming.

O beautiful for [stormy] skies,
For amber waves of [sand];
For purple mountain majesties
Above the [flooded] plain!
America! America!
God shed His grace on thee,
And crown thy good with brotherhood,
From sea to [encroaching] sea.
