As scientists continue to show, the oceans absorb CO2 and keep it from going into the atmosphere. Thus, they help to protect against global climate change. However, this is looking to be perhaps an even bigger problem than climate change!

When oceans absorb this CO2, it makes them more and more acidic. “Since the industrial revolution, the ocean acidity has increased by 30%,” according to Lisa Suatoni, Ph.D. If we continue polluting CO2 as we are now, “ocean acidity will double by the end of the century compared to pre-industrial times. That is a big problem.”

A beautiful short video of the issues related to this, the oceans, and the challenge we are facing follows. It includes commentary from leading scientists and narration by Sigourney Weaver.

One of the best videos I’ve seen in a long time!

According to the NAU researchers, the warming that occurred in the 20th Century and early 21st Century, “contrasts sharply” with the millennial-scale cooling trend; the last half-century being the warmest in the record, and, the decade from 1999 - 2008 being the warmest decade of the last 200 decades. Over all average temperatures were 1.4° C (about 2.5° F) warmer than the projected value based on the linear cooling trend.

A new study by nearly 30 of the world’s best scientists concludes that we have crossed three of the world’s nine thresholds. It is not only about climate change.
