New York Times: Russ George, a California businessman, sprinkled 100 tons of iron dust into the Pacific Ocean off western Canada. The purposes for this iron fertilization, for which a “native Canadian group” paid $2.5 million, appear to have been to stimulate the growth of plankton that absorbs carbon dioxide and settles to the bottom, to boost the salmon harvest, and to investigate selling carbon offset credits. “Marine scientists and other experts have assailed the experiment as unscientific, irresponsible and probably in violation” of international agreements “intended to prevent tampering with ocean ecosystems under the guise of trying to fight the effects of climate change.” Mark Wells, a University of Maine marine scientist, called it “extraordinarily unlikely” that the experiment permanently removed CO 2 from the atmosphere. George reportedly claimed the experiment was not related to geoengineering.

Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
