July's climate: Chilly USA, torrid globe

While the Northeast USA was indeed chilling out in July, take a look at these statistics, courtesy of the University of Alabama – Huntsville: For the world as a whole, July was the 2nd-warmest ever recorded, the Southern Hemisphere had its 2nd-warmest month ever (compared to seasonal norms), and it was the 2nd-warmest month ever recorded in Antarctica (again compared to seasonal norms).

According to Christy, the global average temperature jumped 0.41 Celcius from June to July, the largest one-month jump in the 31-year global temperature record. The global average went from normal in June to the second-hottest July on record.

"Part of that is an artificial artifact of where we put the calendar boundaries," Christy said in an e-mail. "Warmth from the new El Nino was not felt at all in June but really got going almost from the first day of July."

So while El Nino certainly contributed to the spike in global temperatures, no previous El Nino had ever warmed the Earth to that degree, indicating that some other forces are at play.
