 Shutting off river discharge into the ocean causes a rise in global average sea surface temperature by 0.5 °C, an increase of about 10% in Indian summer Mansoon rainfall, and changes in La Nina-like cooling events and their correlation with Pacific SST anomalies, all due to teleconnections between Pacific SST anomalies and Mansoon via upper tropospheric meridional temperature gradient and the North African Asian jet axis.
