what's going to happen to the american sououthwest? are e they going to lose their snowfall? in that sense, there's not a whole lot of robustness between the model simulations yet, so they give different answers in different regions, and so we don't have a good handle, i think, on how rainfall, for exaxample, is goingng to changea warming clclimate. and that't's really i think one of the key things that we need to better understand is where is the water going to be? because a lot of regions depend very strongly, for example, on the glacier, to feed the city and provide all the water for a city like santiago, chile, for example, and so better understanding on how precipitation is going to change and snowfall is going to change is one of the key things that we need to understand. wwe do see t that if youou run point-lititigation scecenarios anand you rededuce ththe amount o of greenhououse , that t you can acactually bririe icice back. yoyou can stababilie amamount of i ice loss. i if wee toto reduce ouour greenhououse , it's not going to be this runaway effect. we can stop som
