That big red whomp in the tropical Pacific, hitting the entire west coast and crossing over Mexico into the Atlantic is el nino. It is a big ton of warmth that was in the ocean, being spit out. Started a few months ago and is projected to continue. Along with previous global warming, this should produce record temp months and a record temp 2015.
Obviously it is already crushing the pacific northwest and according to many projections it is JUST GETTING STARTED. Although, also, you NEVER KNOW because sometimes they just peter out.
This might be the year for that big hurricane although you NEVER KNOW. It's just theoretical right now
