Study: Fresh water is pouring into the Arctic Ocean. Climate change is to blame

CBC discusses how fresh water is pouring into the Arctic Ocean. Climate change is to blame, new study says. The effects of the changes may already be in motion too, researcher says.

The Arctic Ocean is not as salty as it used to be — and now researchers say climate change is to blame. The effects of the changes may already be in motion, too.

Previous research pointed to natural cycles as the cause for an unexplained influx of fresh water on the surface of the world’s northernmost sea in the last few decades.

But a new study, published on July 27 in Geophysical Research Letters, suggests that human caused climate change is what’s driving the increased amounts of freshwater into the Arctic Ocean.
