On the other hand, a view may be taken that points to the benefits of improved information over time. This may suggest an approach where near-term emissions abatement is more modest. Another way of viewing the problem is to look at the potential irreversibility of future climate change impacts (e.g., damages to ecosystems) against the irreversibility of making investments in efforts to reduce emissions (see also Economics of climate change mitigation#Irreversible impacts and policy). Overall, a range of arguments can be made in favour of policies where emissions are reduced stringently or modestly in the near-term (see: Economics of climate change mitigation#The mitigation portfolio).
