Description: Discusses the BOREAS research program, which investigated the "missing carbon" problem in global carbon cycle studies.
Mystery of the Missing Carbon : Feature Articles Implications for Global Climate Compared to other ecosystems, the boreal forest responds relatively quickly to changes in climate. Moreover, analysis of meteorological trends from 1961-90 shows that temperature increases are occurring most rapidly over the interiors of continents at high latitudes (43°N to 65°N)–precisely the location of the boreal forest. In the last 40 years, average temperatures have increased over these regions by as much as 1.25°C per decade (Sellers et al. 1997). If the world’s missing carbon is in fact being stored within the boreal forest, and if the present warming trend is turning the boreal forest into a source of carbon, then there could be a significant increase in the rate of carbon build-up in the atmosphere. Scientists fear that by the year 2100 the amount of carbon dioxide in the atmosphere might actually double pre-industrial levels (Wofsy 1999)–to more than 560 parts per million (the 1990 level was 353 parts per million).
