In these simulations, climate change alone by 2050 results in significant increases in yield under both scenarios only in three northern European countries. But adding estimated effects of higher CO2 concentrations on plant growth increases that yields considerably, with yield increases now being significant in all of the ten countries included in the study. Whether such increases due to higher CO2 concentration would actually be realized is uncertain, because of problems in extrapolating from idealized laboratory and modeling results to field conditions.The clear message of this work is that greater efforts are needed to take account of the “noise” of natural climate variability when considering the “signal” of climate change. In particular, care must be taken in interpreting the results of impact assessments, especially those which use climate simulations over short periods only.Much more remains to be done. For example, the use of simulated monthly climate data by Hulme et al, even when interpolated to daily data by statistical methods, leaves open the possibility of systematic changes in day-to-day variability and extremes due to climate change. These could well dominate the effects of climate change on both river flow and wheat yield. Taking them into account will require the analysis of daily output from the climate models, especially at fine spatial resolution.More importantly, in understanding the message from Hulme et al, we need to distinguish between confidence levels used for the detectability of simulated or real impacts due to climate change, and those needed to decide if the information about possible future impacts is useful for decision-makers. Detectability, used as evidence of climate change, arguably requires a high level of confidence, say, at the 95% or 99% level. On the other hand, if we take it as a given that climate change is occurring, and we are seeking useful advice as to what the consequences might be, a lower level of confidence may suffice.Studies of the length of a data set is necessary to detect a real change in the mean against a background of variability, for example for detection of trends in total ozone or river flow, indicate that even if the change is real, it may need to have happened for decades before it can be shown statistically to have occurred. In cases such as estimation of flood frequency and of the occurrence of moisture stress in crops, what is needed to identify future “dangerous” levels of climate change, or to plan adaptation measures, is an estimate of changes in the probability of such effects before they happen.1.
