From “Local weather Management and the Oceans”: With out a clear image of how the ocean is overturning and with out an correct time scale for interacting with the environment, oceanographers and meteorologists alike can not adequately clarify the final mechanism of Earth’s local weather. Now people with their carbon dioxide producing trade have turn out to be one other unknown modifying issue. The affect of this new and geologically distinctive issue can work in a number of instructions. It might be heading in the direction of a brand new ice age, or it may spawn one other nice tropical period just like the one which prevailed when coal and oil had been mined. The interactions are so concerned that specialists do not but know methods to classify them. You’re sure of 1 factor – this affect is at work on a scale that dwarfs all earlier adjustments man has made.

From “A Sterile Sea”: The modification begins. “People, a terrestrial organism, have an effect on the chemical composition of seawater greater than every other species that stay within the marine setting,” stated Edward D. Goldberg, professor of chemistry on the Scripps Establishment of Oceanography. For instance, about 3,000 tons of mercury from pure continental sources and 4,000 tons from fungicides and industrial processes enter the oceans yearly; lead within the oceans from car gas is “roughly equal” to that from sedimentation; Pesticides, “a brand new and novel addition to the marine setting,” are widespread at this time, as are radioactive species; and people have launched two new components: sanitation and unintended air pollution from human trafficking. Maybe half of all these pollution are launched into the oceans by actions in the US
