FYI
Some say the current weather we are experiencing in the western US is not indicative of a trend fostered by anthropogenic forcing of the radiative balance, but rather El Nino–warmer sea surface temperatures in the Pacific Ocean.
Large-scale weather events like warmer sea surface temperatures (like El Nino), affect dependent weather (sub) systems like drought, or rain storms, or beautiful August nights. Systems like ENSO (El Nino), the AO, the PDO, or the NAO have sway over smaller weather events.
