This year’s biggest climate change news was that 2014 was hottest year on record. Turns out, there’s bigger news: It was also the hottest year in the oceans, which are warming so fast they’re literally breaking the NOAA’s charts.
Don’t think you mind a little jacuzzification in your ocean? You’re wrong. Warmer oceans matter because “global warming” doesn’t just mean above average air temperatures over the course of a year — it actually refers to an increase in the total amount of heat energy contained in the Earth’s systems. While air temperatures can fluctuate on any given year, they are usually matched by an increase or decrease of the amount of heat stored in the oceans (which, by the way, absorb around 90 percent of total global warming heat). To know whether the system as a whole is getting warmer or not, scientists need to take into account the temperatures of the atmosphere, land, AND oceans.
Luckily, NOAA has been tracking ocean energy data for decades, updating its charts every few months. Unluckily, the newest data shows that, on top of 2014’s record-breaking air temperatures, ocean temperatures have also increased — to put it in layman’s terms — a shit ton. The spike is so significant that NOAA will have to rescale its heat chart…more
