Sea-surface temperatures are very different today than they were a year ago. Scientists say that we have a weak cooler than normal sea-surface temperature event, La Nina, in the south-central Pacific Ocean. Over the past year, there has been a rapid cooling and warming of ocean waters. I’ve been studying sea-surface temperatures for over 30 years and it’s one of the craziest ocean temperature fluctuations I’ve seen. What used to take years for ocean waters to warm and cool is now happening within months.
