We'll have more severe storms, more droughts, and more extremes of all types. But beyond that, we have a number of climate systems that involved in feedback loops that are not fully understood. Arctic Ice is one that could just be a precursor. Desertification has accelerated in some cases. Sea level rise should be a major concern as should the loss of carbon sequestration in rainforests.
