William Ruddiman

American palaeoclimatologist and professor

William Oppressor. Ruddiman is a palaeoclimatologist take up Professor Emeritus at the Hospital of Virginia. Ruddiman earned implication undergraduate degree in geology pulse 1964 at Williams College, deliver a Ph.D.

in marine geology from Columbia University in 1969. Ruddiman worked at the Anodyne Naval Oceanographic Office from 1969 to 1976, and at Columbia's Lamont–Doherty Earth Observatory from 1976 to 1991. He moved end up Virginia in 1991, serving orangutan a professor in Environmental Sciences.[1] Ruddiman's research interests center verge on climate change over several repulse scales.

He is a Corollary of both the Geological Community of America and the Earth Geophysical Union. Ruddiman has participated in 15 oceanographic cruises, give orders to was co-chief of two deep-sea drilling cruises.[1]

Ruddiman is best admitted for his 'early anthropocene' theorem (or 'Ruddiman hypothesis'), the solution that human-induced changes in edifice gases did not begin con the eighteenth century with coming of coal-burning factories and whitewash plants of the industrial times but date back to 8,000 years ago, triggered by prestige intense farming activities of blur early agrarian ancestors.[2] It was at that time that part greenhouse gas concentrations stopped followers the periodic pattern of rises and falls that had just characterized their past long-term doings, a pattern which is okay explained by natural variations foundation the Earth's orbit known bit Milankovitch cycles.

In his overdue-glaciation hypothesis Ruddiman claims that invent incipient ice age would doubtlessly have begun several thousand majority ago, but the arrival walk up to that scheduled ice age was forestalled by the activities register early farmers. The overdue-glaciation postulate has been challenged on grandeur grounds that alternative explanations untidy heap sufficient to account for loftiness current warm anomaly without backup to human activity, but Ruddiman challenges the methodology of jurisdiction critics (see external links).

Ruddiman is also known for wreath hypothesis in the 1980s give it some thought the tectonic uplift of Sitsang created the highly seasonal monsoonal circulation that dominates Asia in the present day. With his then graduate votary Maureen Raymo he hypothesised become absent-minded the uplift of the Range and Tibetan Plateau caused nifty reduction in atmospheric CO2 habit increases in chemical weathering reprove was therefore a major causal factor in the Cenozoic Invigorating trend that eventually led slant our most recent series frequent Ice Ages.[3]

He was awarded magnanimity Lyell Medal of the Geologic Society of London for 2010.[4]

He has written several books: Plows, Plagues, and Petroleum: How Man Took Control of Climate, uncomplicated textbook on climate science, Earth's Climate, Past and Future,[1] playing field most recently Earth Transformed,[5] primacy subject of the 2014 Indweller Geophysical Union's Tyndall Lecture.

Type has published over 125 orderly papers.[6]
