Climate change is warming the North Pacific Ocean, leading weather patterns that drive drought in the U.S. Southwest to ...

These mood swings include a climate phenomenon known as Pacific Decadal Oscillation, or PDO. It's an El Nino- like shift in the ocean's temperature that scientists once thought cycled every 15 to ...

The Southwest United States is currently facing its worst megadrought of the past 1,200 years. According to a recent study by ...

"Water managers need to start planning for the possibility that this drought isn't just a rough patch—it could be the new reality," said Timothy Shanahan.

Last week, I wrote a long story about a phenomenon called the Pacific Decadal Oscillation or PDO, a naturally occurring wobble in the planet’s climate system that involves the burial and release ...

The Pacific Decadal Oscillation describes water conditions in the tropical Pacific Ocean that drive global climate conditions. Scientists have long observed the PDO alternates between warm and cool ...

The cooler and drier conditions in Southern California over the last few years appear to be a direct result of a long-term ocean pattern known as the Pacific Decadal Oscillation (PDO), according ...

Analysis by a team of meteorologists suggest another pair of atmospheric patterns, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation, or AMO and PDO, aren't real.

The most compelling argument for a renewed surge in global air temperature is rooted in the Pacific Decadal Oscillation (PDO). This index tracks the fingerprint of sea surface temperature (SST ...

Move over El Nino: Scientists now have their eyes on another, stronger climate pattern that could deliver rain to Southern California for years.

The Pacific Decadal Oscillation is a pattern of change in the ocean's climate. The PDO is detected as warm or cool surface waters in latitudes above 20 degrees North.
