[Editor’s note: Interactive map shows proposed renewable energy power plants and transmission lines in the United States and Canada. The print version by Martin Gamache and Sam Pepple is worth a look –– it composites the multiple themes into a single view, and compares with the current state of the power system in a separate map.]

Can we fix the infrastructure that powers our lives?

We are creatures of the grid. We are embedded in it and empowered by it. The sun used to govern our lives, but now, thanks to the grid, darkness falls at our con­venience. During the Depression, when power lines first electrified rural America, a farmer in Tennessee rose in church one Sunday and said—power companies love this story—”The greatest thing on earth is to have the love of God in your heart, and the next greatest thing is to have electricity in your house.” He was talking about a few lightbulbs and maybe a radio. He had no idea.

Juice from the grid now penetrates every corner of our lives, and we pay no more attention to it than to the oxygen in the air. Until something goes wrong, that is, and we’re suddenly in the dark, fumbling for flashlights and candles, worrying about the frozen food in what used to be called (in pre-grid days) the icebox. Or until the batteries run dry in our laptops or smart phones, and we find ourselves scouring the dusty corners of airports for an outlet, desperate for the magical power of electrons.

Another difference: Modoki’s precipitation patterns are the reverse of El Niño’s—making the American West, for instance, drier rather than wetter.”]

It used to be simpler. Whenever the surface waters of the equatorial Pacific turned warmer than normal in summer, climatologists would expect an El Niño year, then forecast when and where droughts, floods, and hurricanes might occur. But that was before a study by Georgia Tech scientists, led by Hye-Mi Kim, deciphered the effects of another pattern in which high temperatures are confined to the central Pacific (Click this link to expand the graphic). Now the already difficult field of atmospheric forecasting has become even trickier.
