Massive New Study: Ocean Temperatures Rising Faster Than Expected

Here’s a thorough and important story from The New York Times about a new scientific analysis showing that ocean temperatures are warming much faster (up to 40 percent faster) than had been previously predicted, with serious implications for marine life, sea levels and future hurricanes:

Scientists say the world’s oceans are warming far more quickly than previously thought, a finding with dire implications for climate change because almost all the excess heat absorbed by the planet ends up stored in the waters.

A new analysis, published Thursday in the journal Science, found that the oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago. The researchers also concluded that ocean temperatures have broken records for several straight years.

“2018 is going to be the warmest year on record for the Earth’s oceans,” said Zeke Hausfather, an energy systems analyst at the independent climate research group Berkeley Earth and an author of the study. “As 2017 was the warmest year, and 2016 was the warmest year.”

As the planet has warmed, the oceans have provided a critical buffer. They have slowed the effects of climate change by absorbing 93 percent of the heat trapped by the greenhouse gases humans pump into the atmosphere.

“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much faster than it is right now,” said Malin L. Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University. “In fact, the ocean is saving us from massive warming right now.”

But the surging water temperatures are already killing off marine ecosystems, raising sea levels and making hurricanes more destructive. As the oceans continue to heat up, those effects will become more catastrophic, scientists say. Read more:
