His undergraduate courses link climate science with physical hydrology and plant biology, with a particular emphasis on northern environments. For the past three decades, graduate students have driven his northern field research program, which focuses on the water balance and greenhouse gas exchange from the peatlands and ponds in the Hudson Bay Lowlands based out of the Churchill Northern Studies Centre in Churchill Manitoba. In collaboration with the Toronto and Region Conservation Authority, Professor Bello and graduate students maintain four flux stations within the City of Toronto where climate change effects on evaporation and the potential for wind derived electrical energy production are examined.
