“…In North America, potential reductions in the outflow of the Great Lakes could result in significant economic losses as a result of reduced hydropower generation both at Niagara and on the St. Lawrence River (Lofgren et al, 2002). For a CGCM1 model projection with 2°C global warming, Ontario's Niagara and St. Lawrence hydropower generation would decline by 25-35%, resulting in annual losses of Canadian $240-350 million at 2002 prices (Buttle et al, 2004).…”

“…[WGII 4.2] For a 2-3°C warming in the Columbia River Basin and British Columbia Hydro service areas, the hydro-electric supply under worst-case water conditions for winter peak demand will be likely to increase (high confidence). Similarly, Colorado River hydropower yields will be likely to decrease significantly (Christensen et al, 2004), as will Great Lakes hydropower (Moulton and Cuthbert, 2000;Lofgren et al, 2002;Mirza, 2004). Lower Great Lake water levels could lead to large economic losses (Canadian $437-660 million/yr), with increased water levels leading to small gains (Canadian $28-42 million/yr) (Buttle et al, 2004;Ouranos, 2004).…”

“…Many of the historical studies addressing this issue are based on the so-called Bchange factor^method, which is typically applied to a suite of models known as the Advanced Hydrologic Prediction System (AHPS; e.g. , Croley 1990;Hartmann 1990;Lofgren et al 2002;Angel and Kunkel 2010;Hayhoe et al 2010). The change factors in climate variables, typically derived from different Global Climate Model (GCM) projections, serve to perturb observed historical time series.…”

“…It is noted that scenarios of climate change have typically been structured as percent change from the 1960-2000 period, as a means of establishing a baseline relative to, for example, the year 2050, the projected year in which there is considered the potential for a doubling of CO 2 in the atmosphere (e.g. after Lofgren et al, 2002). In this context, trend extrapolation of the historical data using the regression equations for each of precipitation, temperatures, and flows, are summarized in Tables 5 through 7, respectively.…”

“…From Table 5, if the trends apparent over the 1930-2000 time period continue, the predicted increases in precipitation with their uncertainties at the Lakes of Superior, Michigan, Huron, Erie, and Ontario till 2050 are 4.1%±4.9%, 12.50%±4.5%, 10.9%±4.8%, 21.8%±8% and 19%±5 %, respectively. GCMs are being used to develop future scenarios under changed climate conditions (Mortsch et al, 2000). For illustration purposes, the GCM predictions for future changes in precipitation for Lake Superior, Lake Michigan and Lake Huron (the latter two combined to Michigan/Huron) from Lofgren (2002) are plotted in Fig. 5a and b.…”
