Gong and Wang (2000) reported severe summer rains in East China at the rate of 47 mm/decade linear trend in 33 station mean during 1977-1998, unprecedented in recorded history. They suggested that global warming may be the cause. Extreme rainfall events in summer have been causing a significant positive trend in percentage rainfall during storms and other severe events in the US report the authors citing Karl and Knight(1998). This article reports on disaster events caused by dams, in particular, a severe trend in increased annual rains occurring in regions in India and compares that in China and finds them similar as expected. The mechanism is explained in terms of surges of giant sledge hammer effects in the form of water pressures of up to and even more than 100 km per sec every second
at the centres of gravity of heavily dammed regions because of rapid rise in reservoir contents(See Earthquakes Caused by Dams at the Link http://earthquakescausedbydams.blogspot.in ). This is done here by examining data from the 2010 summer monsoon in India and for the period from 1950-2008. These surges are felt as various forms of disasters like sudden hotspots, rainstorms, flash floods, firestorms, heat waves, hurricanes, tornados, landslides, mine cave ins and earthquakes(See Collaterals of Climate Change at the link: http://collateralsofclimatechange.blogspot.in ). Thus dams change climate because of the continuous nature of their cumulative effects on the earth, like direct heating up by exerting water moments from their centre of gravity. The recent Uttarakhand disaster(14 to 20 June 2013) is a direct consequence of dams which destroyed dams in the valley apart from taking lives and creating landslides by uplift and subsidence of the earth. Dams as a means of meeting water demands have to be given up in favour of rapid emergency waves of ecological forest rejuvenation now. See Glaring Lacuna in Meeting Water
Needs by Dams at the link: http://glaringlacuna.blogspot.in/2011/04/glaring-lacuna-in-meeting-water-needs.html . The reason is that dams are slaves of gravity while forests transpire, respire and are giant pumps throwing up water into the atmosphere after sucking them up from the groundwaters and redistribute water in proportion to the density of
vegetation and prevent the phenomenon of dynamic disequilibrium of the continuous surges of forces and water moments exerted on the earth. See Reforest Mother Earth to Live at the link: http://practicethevedas.blogspot.in
Rainfall and Dam build up.
The four regions in India having differing monsoon rainfall are the Northwest, the Northeast, the Central and the Southern Peninsular
Region. The rains in these regions together are significantly increasing with Annual All India Dam Capacity as Figure 1 shows:
Table 1: Sum of Monsoon Means of NW,NE,CI and South Peninsular
Let us see the picture for East China from 1977 to 1998 for the rainfall increase with China Dam Capacity(Figure 2). The trend is indeed a significantly increasing one for the East China Rainfall with China Annual Dam Capacity as noted from the correlation of Rain with Dam Capacity.
Let us now zoom into the picture for the Southwest Monsoon in India for 2010:

recent disasters: one in Uttarakhand, India and the other in Arizona,
US show us—that not only ecological devastation but also human
casualty—arise from climate change. In both cases, those who tried to
save lives—lost their lives
