Future evolution of the Yerba Loca glaciers (shown in black): 2016 -2040.

Jansson et al. , 2003 Melt of the “deglaciation discharge dividend” (Collins, 2008) until a maximum peak level is attained, subsequently decreasing when the glacier is not able to sustain such large melt water production due to is reduced size, until finally the discharge drops to the base flow level when glacier extinction is reached.

Hypothetical shift from a glacio-nival regime to a more nivo-pluvial regime at Maipo River at El Manzano station (850 m asl), central Chile, as a response to a future warming scenario under constant annual precipitation, which is consistent with model predictions (e. g. Serrano, 2014).

LATIN AMERICA STRENGTHS/WEAKNESSES • STRONG Group on Glacier Mass Balance, sponsored by UNESCO IHP, already data providers to CRYONET • WEAK representation of SNOW + PERMAFROST research: good opportunity for GCW involvement together with IHP (SNOW) & IPA (Permafrost)
