Atmospheric 'teleconnections' sustain warm blobs in the northeast Pacific Ocean

The past 10 years have seen a series of "warm blobs" in the northeast Pacific Ocean. These marine heat waves do widespread damage to ecosystems and marine life in the area, but the mechanisms by which they develop and are sustained are still uncertain. Now a research group has found that they are caused by climate "teleconnections" from wave trains that originate in the Mediterranean Sea and North Atlantic region.
