I remember talking about Everest, getting caught up in excitement, and he told me, Someday, youll turn your gaze from the summit to the valleys, because thats what really matters. I may have climbed this mountain, but my more important work would follow that. These retreats will increase the variability of water flows to downstream areas and endanger the sustainability of water use in the earths most crowded basins. The retreat means countries like Nepal and Bangladesh, which rely on these mountain water cycles, will have to adapt. People go there just to get a feather in their cap. I thought I could apply my skills to do something meaningful. Most of the black carbon falling on the Himalayas and the south of the Tibetan plateau comes from the plains of India, while that of the eastern and northern sections of the plateau comes mainly from China.According to recent ICIMOD estimates, black carbon is probably responsible for a large part - around 30 percent by some calculations - of glacial retreat in the region.ICIMOD and other bodies admit there is far too little field data available to draw solid conclusions, whether on overall glacial melt or on the influence of black carbon.
