Earth's Oceans --"Sending Scary Global Warming Signal" - The Daily Galaxy --Great Discoveries Channel

“If you want to see where global warming is happening, look in our oceans,” said Zeke Hausfather, at the Energy and Resources Group at the University of California, Berkeley, and co-author of the paper. “Ocean heating is a very important indicator of climate …

  Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations.

  The new analysis, published Jan. 11 in Science, shows that trends in ocean heat content match those predicted by leading climate change models, and that overall ocean warming is accelerating.

  Assuming a “business-as-usual” scenario in which no effort has been made to reduce greenhouse gas emissions, the Coupled Model Intercomparison Project 5 (CMIP5) models predict that the temperature of the top 2,000 meters of the world’s oceans will rise 0.78 degrees Celsius by the end of the century.

  “The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report, published in 2013, showed that leading climate change models seemed to predict a much faster increase in ocean heat content over the last 30 years than was seen in observations,” Hausfather said.

  Three of the new studies included in the Science analysis calculated ocean heat content back to 1970 and before using new methods to correct for calibration errors and biases in the both the Argo and bathythermograph data.
