ADJUSTING TO LONGER AND DRIER SUMMERS IN BRITSH COLUMBIA: “Since 2000, summer precipitation has dropped about 20 per cent. This means we need to be far more conscientious about summer water use,” stated Hans Schreier, a professor emeritus of land and water systems at the University of British Columbia (July 2021)
Climate change has aggravated an existing vulnerability related to seasonal supply of water in BC. “Most long-term climate stations within the Lower Mainland region of British Columbia have a 50 to 75-year record. Over this time period, there had been an increasing trend in summer precipitation (May-Aug) until around 2000. Since that time (2000-2020), however, there has been a step change to a lower rate of precipitation of around 20 percent,” explained Hans Schreier.
