As more vegetation was removed by the introduction of livestock, it
increased the albedo (the amount of sunlight that reflects off the earth's surface) of the land, which in turn influenced atmospheric conditions sufficiently to reduce
monsoon rainfall.
The development of active freshwater systems during these periods corresponds with
monsoon intensity
increases during insolation maxima, suggesting that humid periods in Arabia were not confined to eccentricity - paced deglaciations, and providing paleoenvironmental support for multiple windows of opportunity for dispersal out of Africa during the late Pleistocene.

increase, compared to the anthropogenic predicted contribution of 2.6 % per degree of global warming.
So while the
monsoon winds might weaken the precipitation nonetheless
increases (more bang for the buck) as a weaker circulation carries more water vapor (and latent energy).
There is a theory that the rising of the Himalayas and the Tibetan plateau provided the barrier that made the South Asian
monsoons possible, and a secondary theory that the
increased rainfall on the freshly raised mountain slopes weathered so much rock that the planet's levels of atmospheric carbon dioxide took a dive, to precipitate 30 million years of Ice Ages.
In ECHAM4 and HadAM3a,
increased resolution has little impact on the negative surface pressure bias over the tropics but improves the low - level South Asian

Similarly, if there is an

The main dynamical driver of the
monsoon is therefore the positive moisture - advection feedback (Fig. 1 A): The release of latent heat from precipitation over land adds to the temperature difference between land and ocean, thus driving stronger winds from ocean to land and
