Sensitivity of freshwaters to browning in response to future climate change
Many boreal waters are currently becoming browner with effects on biodiversity, fish production, biogeochemical processes and drinking water quality. The question arises whether and at which speed this browning will continue under future climate change. To answer the question we predicted the absorbance (a420) in 6347 lakes and streams of the boreal region under future climate change. For the prediction we modified a numerical model for a420 spatial variation which we tested on a temporal scale by simulating a420 inter-annual variation in 48 out of the 6347 Swedish waters.
