From “Local weather Management and the Oceans”: And not using a clear image of how the ocean overturns and with no correct time scale for interplay with the environment, oceanographers and meteorologists alike are at a loss to clarify adequately the final mechanism of the earth’s local weather. Now man, along with his carbon-dioxide-producing trade, has grow to be yet one more unknown modifying issue. The affect of this new and geologically distinctive issue could also be working in any of a number of instructions. It might be tending towards a brand new ice age or might be producing one other nice tropical epoch like that prevailing when coal and oil deposits had been laid down. The interactions are so concerned that specialists don’t but know learn how to kind them out. One factor they’re certain of—this affect is at work on a scale to dwarf all earlier modifications man has made.

From “A Sterile Sea”: The modification is starting. “Man, a land organism, is influencing the chemical composition of sea water greater than any of the species that stay throughout the marine atmosphere,” stated Edward D. Goldberg, Professor of Chemistry at Scripps Establishment of Oceanography. For instance, some 3,000 tons of mercury attain the oceans every year from pure continental sources and 4,000 tons from fungicides and industrial processes; the lead enter to the oceans from car gas is “roughly equal” to that from sedimentary motion; pesticides, “a current and novel entry to the marine atmosphere,” now are widespread, and so are radioactive species; and man has launched two new components: sewage outfalls and unintended pollutions from man’s commerce. Maybe half of all these contaminants are launched into the ocean by actions within the U.S.
