    THE ERA OF WEATHER EXTREMES IS UPON US: “Ecology is not rocket science. It’s way more complicated. This is not to downplay the difficulty of rocket science, but to point out the incredible complexity of natural systems where all the variables aren’t known and are often connected to and influence one another,” stated Armel Castellan, meteorologist with Environment and Climate Change Canada (December 2021)

    “Recent flooding in southwest B.C. (in mid-November 2021) was connected to the cumulative amount of rain falling in a short period of time. It was also linked to several record-breaking wildfire seasons which reduced tree cover on mountainsides and the vegetation that would normally have helped to absorb and slow water running into streams and rivers. The interconnectedness this year also included the almost unfathomable summer heat dome which set off a chain reaction — early drought, drier forests, and wildfires starting four to five weeks earlier than usual,” explained Armel Castellan.

    ‘HISTORIC, DANGEROUS, PROLONGED AND UNPRECEDENTED’ HEAT WAVE SWELLS OVER PACIFIC NORTHWEST AND BRITISH COLUMBIA: “Perhaps the most intense heatwave for our region since the late 19th century – or at least close to it – is beginning to take shape,” reported the United States National Weather Service in the early morning on Saturday, June 26, 2021

    As of 2015, we clearly crossed an invisible threshold into a different hydrometeorological regime in Western North America. Changes in the global hydrologic cycle have huge implications for every region of the world. “It’s unprecedented,” said Armel Castellan, a warning preparedness meteorologist with Environment and Climate Change Canada, when he described the “dome of heat” that descended on British Columbia in June 2021. “It’s never happened this early in the season. Temperatures are breaking all-time highs in south coast locations in June.”
