Global warming computer prediction models are only as good as their input, and it appears they need more adjusting. A new study has found the ocean’s biological pump captures twice as much carbon as previously thought.
Measurements of carbon captured in the ocean should be taken where the ocean’s sunlit zone disappears, the study says. Previous models used 450 feet as a set reference depth, but the new study took into account the true variable depth between 100 and 550 feet.
How it works: Plankton die or are consumed in a daily cycle that moves carbon from the from the surface to the deep ocean. A “marine snowfall” occurs trapping most of the ocean’s carbon in deep waters where it is stored for hundreds to thousands of years.

Scientists are hoping a tiny nano-scaled, 3d-printed, nonstick-coated, spiral-shaped delivery bot (200 times smaller than the diameter of a human hair) can replace slow, irritating and painful procedures to deliver medicine to the back of the eye and the retina.
It will be years before the nanobots are ready for human testing. First is animal testing and finding how to dissolve the bots once their task is complete.
The nonprofit group The Ocean Cleanup is set to begin cleanup operations in the Pacific. In 2013, 18-year-old Boyan Slat proposed using the ocean’s currents to expedite a cleanup of the 1.8 trillion tons of plastic trash. More information at The Ocean Cleanup.
