Abstract: | The predicted increase in atmospheric carbon dioxide and the effects of global warming will influence the Wadden Sea, The Netherlands, an area of exceptional ecological value. The direct effect of elevated atmospheric CO2 on terrestrial coastal ecosystems is either marginal or unknown. The slight acidification of the sea which is predicted might have an impact on primary producers and juvenile animals. The effect of CO2 fertilization on marine primary production remains to be elucidated. Profound changes will occur if sea level rises at the predicted rate of 60 cm per century, as sedimentation rates will be insufficient to maintain the salt marshes on the barrier islands. The marshes of the mainland coast will be impoverished, as high and low marshes are not expected to continue to coexist at the same locations. As sediment supply to the Wadden Sea is sufficient to compensate for sea level rise, the estuarine character of the Wadden Sea, with sand- and mudflats, is expected to remain largely unchanged. |
