Published 12:00 pm Saturday, July 11, 2026By Roseanne Van Ee Okanagan's Nature NutIt’s getting hot here. The temperature’s rising. We’re inundated and overwhelmed by disastrous news about climate change. And it’s confusing. We know climate change is the result of polluting our precious life-securing and shielding atmosphere mostly by burning fossil fuels combined with destroying our Earth’s natural environments. But how does this affect us in the Okanagan?The coal, oil and gas we use as fuel energy are remains of decomposed, once living organisms, including plants and animals, that have been compacted and fossilized over hundreds of millions of years. When burned, its dense energy is intense. It releases CO2 that heats up the atmosphere. We know that our temperature is rising, even here in Vernon. Last July, the Allan Brooks Nature Centre celebrated its 25th anniversary. Our Mayor, Victor Cumming, gave a startling speech there revealing Vernon’s weather records of days with a maximum temperature over 35 degrees Celsius. Days reaching 35°C or hotter have become much more common over time, especially since the late1990s. In earlier decades, most years had either normal conditions (based on a 30 year historical averagefrom 1951 to 1980) or fewer extreme-heat days. More recent decades have many more years with above- normal 35°C plus days. After Cumming’s speech, the audience gasped; they were astounded. Here’s the Vernon weather records temperature trend summary he referred to:• 1915–1945 – 30 years: Extreme 35°C days were very uncommon. Some years had slightly more hot days than normal, but many years had fewer. • 1945–1975 – 30 years: Mostly stable or slightly below normal. No long-term increase in very hot days. • 1975–1995 – 20 years: Small temperature increases begin to appear, but most years still remain close to normal levels. • 1995–2000 – 5 years: A noticeable shift starts. Several years record more 35°C days than average, and the temperature trend begins climbing upward. • 2000–2005 – 5 years: Hot extremes become more frequent. Some years are significantly above normal, indicating more regular heat events. • 2005–2010 – 5 years: Sustained high heat continues, with most years above normal and very few cooler-than-normal years. • 2015–2020 – 5 years: Extreme heat becomes much more common. Several years record very large increases in 35°C days. • 2020–2025 – 5 years: The highest temperatures occur here, including years with around 15 to 18 extra 35°C days above normal.
