For more than three years, the Western United States -- especially California -- has been gripped by the worst drought on record. With no end in sight, San Diego County announced plans to build a massive $1 billion desalination plant. The plant will produce drinking water for 300,000 people in Southern California, but opponents have raised concerns about its high energy use, and that it will likely harm marine life. Researchers also discovered what may be causing the drought -- a massive "blob" of warm water in the Pacific Ocean measuring a thousand miles wide is wreaking havoc on weather patterns and local marine life.
