CNN: The oceans are warming faster than scientists thought

The world's oceans are warming at an accelerated rate and are much warmer than scientists thought -- and things could get a lot worse if nothing is done to stop climate change, according to a new study. The data, published in Thursday's edition of the journal Science, shows that the oceans have experienced consistent changes since the late 1950s and have gotten a lot warmer since the 1960s. The oceans are heating up much faster than scientists calculated in the UN assessment of climate change released in 2014.

Though a warmer ocean might make for a more pleasant swim, it carries deadly consequences. A warmer ocean causes sea level to rise, bringing problems like dangerous coastal flooding. It leads to the loss of sea ice, heating the waters even further. It can affect the jet stream, allowing cold Arctic air to reach farther south, making winters more intense, and endanger the lives of animals that depend on sea ice like penguins and polar bears. A warmer ocean also contributes to increases in rainfall and leads to stronger and longer-lasting storms like Hurricanes Florence and Harvey.
