'World may see record warming': NASA scientist tracking El Nino

A NASA satellite, which monitors sea levels, has spotted early signs of El Nino—a periodic climate phenomenon—from space. El Nino affects weather patterns around the world and it is typically associated with higher global temperatures. "We'll be watching this El Nino like a hawk," said Josh Willis, a project scientist at NASA. "If it's a big one, the globe will see record warming."
