Not exact matches

In summer and autumn the CSIRO projections were for smaller decreases in rainfall than in winter and spring, but the observed change was a substantial decrease: in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 203In summer and autumn the CSIRO projections were for smaller decreases in rainfall than in winter and spring, but the observed change was a substantial decrease: in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 203in rainfall than in winter and spring, but the observed change was a substantial decrease: in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 203in winter and spring, but the observed change was a substantial decrease: in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 203in fact, as large a decrease between the successive 11 - year periods as CSIRO projected on the high global warming scenario over the 40 - year period from 1990 to 2030.

However, simple statistical reasoning indicates that substantial changes in the frequency of extreme events (and in the maximum feasible extreme, e.g., the maximum possible 24 - hour rainfall at a specific location) can result from a relatively small shift of the distribution of a weather or climate variable.

In contrast, comparing the likelihoods of heavy rainfall during simulated La Niña years with El Niño / neutral years reveals a substantial La Niña influence on Australian rainfall during 2010 — 2012 that is robust to changes in the attribution frameworIn contrast, comparing the likelihoods of heavy rainfall during simulated La Niña years with El Niño / neutral years reveals a substantial La Niña influence on Australian rainfall during 2010 — 2012 that is robust to changes in the attribution frameworin the attribution framework.

If substantial areas of the Amazon are in a climate regime close to the savanna - rainfall threshold, which diverse evidence suggests they are, then there may be a vegetation shift if rainfall consistently decreases in the future due to climate change.
