Water everywhere, resulting in social upheaval, anarchy, and political confusion
Type of Spiritual Experience
HERBERT B. GREENHOUSE was born in Chicago, educated at Northwestern University and the University of Southern California, and served in the Army during World War II. He worked as an advertising copywriter, a playwright for stage, radio, and television, and was also a pianist and composer. An avid investigator of psychic phenomena, Mr. Greenhouse was a member of the American Society for Psychical Research and participated in many ESP laboratory experiments. He was also the author of In Defense of Ghosts, Thoughts of the Imitation of Christ, and How to Double Your Vocabulary. He lived in New Jersey and had a retreat in the Berkshires.
This prophecy is intriguing as it was made well before 1971 when Greenhouse wrote the book and well before we knew about the effects of climate change, although some scientists might have been working on this possibility, as such the person who recorded this may have been tapping into the realm of science or have been a scientist speculating - so not a prophecy at all!
A description of the experience
Premonitions: A leap in to the future – Herbert Greenhouse 
From the Central Premonitions Registry of the American SPR
Starting with 1972-73 it will be a crucial year for the U.S.A. Water everywhere, resulting in social upheaval, anarchy, and political confusion. The people will be looking for a new leader, but none forthcoming. A new political structure will come into being.
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols (e.g., "pollution") could have cooling effects as well. During the 1970s, scientific opinion increasingly favored the warming viewpoint. By the 1990s, as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages, a consensus position formed: greenhouse gases were deeply involved in most climate changes and human caused emissions were bringing discernible global warming. Since the 1990s, scientific research on climate change has included multiple disciplines and has expanded.
