2 Anthropocene
In 2000, in IGBP Newsletter 41, Crutzen and Eugene F. Stoermer , to emphasize the central role of mankind in geology and ecology, proposed using the term anthropocene for the current geological epoch. In regard to its start, they said:
- To assign a more specific date to the onset of the 'anthropocene" seems somewhat arbitrary, but we propose the latter part of the 18th century, although we are aware that alternative proposals can be made (some may even want to include the entire holocene). However, we choose this date because, during the past two centuries, the global effects of human activities have become clearly noticeable. This is the period when data retrieved from glacial ice cores show the beginning of a growth in the atmospheric concentrations of several 'greenhouse gases", in particular C02 and CH4. Such a starting date also coincides with James Watt's invention of the steam engine in 1784Events January 6 the Turks agree to Russia's annexation of the Crimea in the Treaty of Constantinople January 14 The U. Congress ratifies the Treaty of Paris with England to end the American Revolutionary War February 27 Count of St Germain dies of pneumo. [4]
