The simulations <br />are for late this century, under a higher emissions scenario" For example, in the spring, climate models agree that northern areas are <br />likely to get wetter, and southern areas drier. There is less confidence in exactly where the transition between wetter and drier areas <br />will occur. Confidence in the projected changes is highest in the hatched areas. <br />Figure 2 -4. Multi -model changes in precipitation under a higher emissions scenario for the end of <br />the century. Cross - hatches shows regions where at least two- thirds of models agree on the sign of the <br />projected change (Source: Karl et al. 2009). <br />
