It would be quite newsworthy, but perhaps it was a scheduling problem or the stars just didn't line up this year. Maybe next.
But, don't worry, each will join -- according to CNN -- one billion people around the planet in celebrating the annual event.
Is this Heaven?
Obama heads out to Iowa (or Heaven as some have called it). But not Dyersville, the home of the "Field of Dreams". Instead the president commemorates the Earth in Newton, where he will visit a green manufacturing facility that produces towers for wind energy production.
Explains the White House press office:
"Iowa , a leader in wind energy, is a perfect example of how a community can rebuild a local economy with investments in clean energy and efficiency. Trinity employs dozens of former Maytag employees and is part of the revitalization of a town hard hit by the closing of the Maytag plant."
Following the tour of the facility, President Obama will discuss his energy plan. Says the White House, Obama will discuss "promoting clean energy innovation to help end our dependence on foreign oil, creating millions of new jobs, and preventing the worst consequences of climate change."
The president wants $15 billion annually for 10 years directed to the renewable-energy industry.
