	abstract = {<p>Modern climate change is dominated by human influences, which are now  large enough to exceed the bounds of natural variability. The main  source of global climate change is human-induced changes in atmospheric  composition. These perturbations primarily result from emissions  associated with energy use, but on local and regional scales,  urbanization and land use changes are also important. Although there has  been progress in monitoring and understanding climate change, there  remain many scientific, technical, and institutional impediments to  precisely planning for, adapting to, and mitigating the effects of  climate change. There is still considerable uncertainty about the rates  of change that can be expected, but it is clear that these changes will  beincreasingly manifested in important and tangible ways, such as  changes in extremes of temperature and precipitation, decreases in  seasonal and perennial snow and ice extent, and sea level rise.  Anthropogenic climate change is now likely to continue for many  centuries. We are venturing into the unknown with climate, and its  associated impacts could be quite disruptive.</p>},
