The researchers report that over the period of their study, "river discharges in the Qinghai-Tibet Plateau, in general, have no obvious change with the increase of the Northern Hemisphere surface air temperature." Because they could detect, in their words, "no increase in the stream discharge in the Qinghai-Tibet Plateau with global warming," Cao et al. conclude that their real-world findings are not "in accordance with the anticipated ideas" that led them to conduct their study. Indeed, the maintenance of the status quo in this and so many other studies argues strongly against either the claimed consequences of global warming (tending towards catastrophic) or the claimed degree of global warming (already unprecedented) or both of these standard climate-alarmist claims.
