An abrupt climate change 8200 years ago (8.2&amp;nbsp;ka event) provides a test case to understand possible future climatic variability. Here, methane concentration (taken as an indicator for terrestrial hydrology) and nitrogen isotopes (Greenland temperature) in trapped air in a Greenland ice core (GISP2) are employed to scrutinize the evolution of the 8.2&amp;nbsp;ka event. The synchronous change in methane and nitrogen implies that the 8.2&amp;nbsp;ka event was a synchronous event (within ±4 years) at a hemispheric scale, as indicated by recent climate model results [Legrande, A. N., Schmidt, G. A., Shindell, D. T., Field, C. V., Miller, R. L., Koch, D. M., Faluvegi, G., Hoffmann, G., 2006. Consistent simulations of multiple proxy responses to an abrupt climate change event. Proceedings of the National Academy of Sciences 103, 837–842]. The event began with a large-scale general cooling and drying around ∼8175±30 years BP (Before Present, where Present is 1950 AD). Greenland temperature cooled by 3.3±1.1&amp;nbsp;°C (decadal average) in less than ∼20 years, and atmospheric methane concentration decreased by ∼80±25&amp;nbsp;ppb over ∼40 years, corresponding to a 15±5% emission reduction. Hemispheric scale cooling and drying, inferred from many paleoclimate proxies, likely contributed to this emission reduction. In central Greenland, the coldest period lasted for ∼60 years, interrupted by a milder interval of a few decades, and temperature subsequently warmed in several steps over ∼70 years. The total duration of the 8.2&amp;nbsp;ka event was roughly 150 years.&lt;/p&gt;
