The already changed climate is making itself felt. In New Jersey and New York, the seas that have risen about 11 inches inundated areas previous thought to be well outside flood areas. Insurance costs are rising. Homes once outside flood zones are now in them, as the new Federal Emergency Management Agency flood maps of New York City doubled the number of residential and commercial buildings in flood areas, and the latest maps don't even include all areas flooded by Sandy.
In Texas, record heat and drought (climate models years ago predicted increased drought in Texas) are taking a toll. For example, the New York Times reports that a beef processing plant will close, because the drought makes it impossible to keep an adequate regional cattle herd.
The plant had operated for "generations," and its closing will kill a $55 million annual payroll and 2,300 jobs.
In New Jersey, an electric utility is investing $3.9 billion to harden the grid from extreme storms and rising seas, concluding that stronger storms are the new normal. Paying $3.9 billion for a harden grid is expensive but a better option than sitting in the dark and cold for days, weeks, and months.
From Texas to New Jersey, the already changed climate is making itself felt.
