It’s official, I guess. From the story:
In January, the Department of Housing and Urban Development announced grants totaling $1 billion in 13 states to help communities adapt to climate change, by building stronger levees, dams and drainage systems.
One of those grants, $48 million for Isle de Jean Charles, is something new: the first allocation of federal tax dollars to move an entire community struggling with the impacts of climate change. The divisions the effort has exposed and the logistical and moral dilemmas it has presented point up in microcosm the massive problems the world could face in the coming decades as it confronts a new category of displaced people who have become known as climate refugees.
