Abstract. This study reports on three years (2004)(2005)(2006) of measurements of net ecosystem exchange (NEE) over a young Siberian larch plantation in Iceland established on previously grazed heathland pasture that had been scarified prior to planting. The study evaluated the variation of NEE and its component fluxes, gross primary production (GPP) and ecosystem respiration (R e ), with the aim to clarify how climatic factors controlled the site's carbon balance. The young plantation acted as a relatively strong sink for CO 2 during all of the three years, with an annual net sequestration of −102, −154, and −67 g C m −2 for 2004, 2005, and 2006, respectively. This variation was more related to variation in carbon efflux (R e ) than carbon uptake (GPP). The abiotic factors that showed the strongest correlation to R e were air temperature during the growing season and soil water potential. The GPP mostly followed the seasonal pattern in irradiance, except in 2005, when the plantation experienced severe spring frost damage that set the GPP back to zero. It was not expected that the rather slow-growing Siberian larch plantation would be such a strong sink for atmospheric CO 2 only twelve years after site preparation and afforestation.

“…Model simulations indicate that rising temperatures could improve tree growth in the northern boreal zone, while changes in precipitation are not likely to have a major effect on growth at these latitudes (Bergh et al 2003(Bergh et al , 2007Ge et al 2011b). In the southern parts of the Baltic Sea basin, tree growth is strongly water limited (Lasch et al 2002.…”

Climate change affects the vulnerability and productivity of forestry and agricultural systems, predominantly by changes in precipitation and temperature patterns. Indirect impacts are altered risk of damage, for example, by longer periods of drought stress and other biotic and abiotic disturbances. While southern and eastern parts of the Baltic Sea basin are likely to experience a net impact of climate change that is negative for production, northern and western regions are likely to experience a general increase in production. As a result, land-use potentials will change and will foster adaptation and mitigation measures. In the northern region, forest management adaptation may lead to substantial yield increases, while in the south management, adaptation may be required to counter deteriorating conditions. Comparable conclusions can be drawn for agricultural management: if adaptation potentials are fully exploited, substantial yield increases can be expected for certain crop species. In the southern areas and for certain species, deteriorating conditions and possibly increasing climatic variability are projected. Both climate change impacts and human responses will affect socio-economic conditions in the Baltic Sea basin.

Projections of terrestrial carbon (C) dynamics must account for interannual variation in ecosystem C exchange associated with climate change, increasing atmospheric CO 2 concentration, and species dynamics. We used a dynamic ecosystem model to (i) project the potential dynamics of C in New England forests under nine climate change scenarios (CCSs) for the 21st century and (ii) examine the sensitivity of potential C dynamics to changes in climate and atmospheric CO 2 concentration. Our results indicated that forest net primary productivity (NPP) and soil heterotrophic respiration (RH) averaged 428 and 279 gC/m 2 /yr and New England forests sequestered CO 2 by 149 gC/m 2 /yr in the baseline period . Under the nine future CCSs, NPP and RH were modeled to increase by an average rate of 0.85 and 0.56 gC/m 2 /yr 2 during 1971-2099. The asymmetric increase in NPP and RH resulted in New England forests sequestering atmospheric CO 2 at a net rate of 0.29 gC/m 2 /yr 2 with increases in vegetation and soil C. Simulations also indicated that climate warming alone decreases NPP, resulting in a net efflux of C from forests. In contrast, increasing precipitation by itself stimulates CO 2 sequestration by forests. At the individual cell level, however, changes in temperature or precipitation can either positively or negatively affect consequent C dynamics. Elevation of CO 2 levels was found to be the biggest driver for modeled future enhancement of C sequestration. Without the elevation of CO 2 levels, climate warming has the potential to change New England forests from C sinks to sources in the late 21st century.
