For instance, even if warming achieved by 2100 remained constant after 2100, such committed responses continue to occur. These include:  continued Amazon forest loss , consistent with results in Pugh et al.  that found continued tropical forest cover loss across a range of models and simulation setups, and  across Africa, an increased shift towards woody C3 vegetation was found in equilibrium state, the overall response depending on the atmospheric CO2 concentration . In Pugh et al. , the opposite was found for boreal forest cover, which showed a strong committed increase. The committed changes in vegetation composition correspond to large committed changes in terrestrial carbon uptake and losses , and would plausibly also appear in other ecosystem functioning and services. These studies point to the importance of having not only a multi-decadal but also a multi-century perspective when exploring the impacts of political decisions on climate change mitigation taken now. Even if climate-warming targets are met, published evidence so far suggests that fundamental changes in some ecosystems are likely as these correspond to well-understood ecosystem physiological responses that trigger long-term changes in composition.
