    Abrupt, climate-induced increase in wildfires in British Columbia since the mid-2000s

    Abrupt, climate-induced increase in wildfires in British Columbia since the mid-2000s

    Communications Earth & Environment volume 4, Article number: 309 (2023)

    Abstract

    In the province of British Columbia, Canada, four of the most severe wildfire seasons of the last century occurred in the past 7 years: 2017, 2018, 2021, and 2023. To investigate trends in wildfire activity and fire-conducive climate, we conducted an analysis of mapped wildfire perimeters and annual climate data for the period of 1919–2021. Results show that after a century-long decline, fire activity increased from 2005 onwards, coinciding with a sharp reversal in the wetting trend of the 20th century. Even as precipitation levels remain high, moisture deficits have increased due to rapid warming and increased evaporative demand. Bottom-up factors further influence fire activity, as the legacy of past wildfires, insect outbreaks, and land-use practices continually influence fire regimes. The compound effects of climate-induced moisture changes and altered fuels now force British Columbians to confront the harsh reality of more frequent years of intense and prolonged wildfire activity.

    Forests MUST burn to renew...been happening forever.

      And the same as those neglected dams and dikes in Lybia and prairie suma region so it is with neglected forest management. You can't blame it on climate change. Try all you want.

        "Even as precipitation levels remain high, moisture deficits have increased due to rapid warming and increased evaporative demand."

        "four of the most severe wildfire seasons of the last century occurred in the past 7 years: 2017, 2018, 2021, and 2023." !!!!

          There is a very reliable marketing adage. high prices cure high prices, and low prices cure low prices.

          Apply that to forest fires and the exact same thing applies. A period of low forest fires will build up the fuel which will cure the period of low forest fires. Resulting in a period of high forest fires consuming the excess fuel, which will give a deficit of fuel resulting in a period of low forest fires, repeated ad infinitum. Intermixed with the eternal climate cycles.
          The current cycle happens to have the additional bonus of the entirety beneficial higher levels of CO2 resulting in faster growth of forests and more area of forest, meaning even more fuel.

          To visualize the idiocy of Chuck's forest fire theory, extend it out far into the future. So under his theory, every year will be worse than the previous year, burning more acres. Ignoring the obviously incorrect assumption that this climate cycle would continue on abated forever, you realize that exponential growth of forest fires such as he promises cannot continue forever in a finite world.
          Meanwhile, the US is experiencing one of the lowest years in its history for number of acres burned by forest fires. Not sure how that fits into the agenda of global warming. Looks more like cherry picking one country and one year and one metric.

            Wildfires are part of the natural forest cycle. Only worse now as the maturity of the forests and the amount of deadfall has reached a tipping point, where it’s time to renew. Hence fire. And big fires because humans have been trying to stop them for the last 100 years or so. It’s so bad that in the Banff area, I see they are cutting up deadfall’s and burning them in the wintertime to try to reduce the risk of fire in the summer.

            The smoke blocks out the Sun and cools the atmosphere. It can also increase precipitation if moist air comes along as water vapour will attach to particles in the air. Isn’t that what you want Chuck?? Or is cooling bad? Warming bad? More rain bad? Less rain bad? Everything is bad?

            It’s climate. It never stays the same. 4 seasons is the only sure thing. There is millions of combinations of temperatures and precipitation in season, in a year, hence I will agree, the climate has always been changing. Remember, mile thick ice, right here, and no fossil fuels. Why is it gone?

                  The only question I have is: how many wildfires are due to federally sponsored arson? After premier Smith sent out Arson investigators the fires shifted to BC and the territories.

                    Some yrs climate change is real bad.

                    Some yrs it goes away?

                      The climate has always changed! No shit?

                      So greenhouse gases don't cause climate change?

                      The evidence is clear humans are causing a very significant amount of climate change, but not all of it.

                      The last time CO2 levels were this high was 3 million years ago and temperatures were much warmer than present. Most of the recent warming has gone into the oceans.

                      "The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago."

                        So..
                        What do you propose we do about it?
                        Id go full electric and huge huge solar arrays if we could. But right now we just cant. My combines still run diesel.
                        So does everything else.

                        I did notice how you always seem to glass over any particularly insightful comments chuck chuck..
                        Or the other day in another psot when i mentioned how you fail to lambaste our selling of coal to china...but constantly go after albertans and danielle smith * she sucks by the way..just as a human* and everything that makes canada hummm......

                        Probably just glass over this again eh?
                        Or the previous comment about how forest fire fuel increases..and increases.. over time..

                        Kind of like baby boomers and canadian population...
                        Eventualllyyy our boomer population was going to get old and be a real drain on our healthcare system ( alcohol...ciagarettes in the 60s thru 80s.) Then when the system becomes overrun and there arent enough places to do hip surgery....wellll... the sky is falling!

                        Then they all die...and our population decreases more rapidly than in the past

                        Just more ripening fuel for the grim reaper...

                        But seriously tho.
                        Chuck
                        All you do is post stuff. Know itll get a rise out of everyone on here. Thats called a troll.
                        Dont be a troll.. be the change you wish to see.
                        Im trying my best.
                        Are you?

                            Russia has 3 times the boreal forest that Canada does and they had no wild fires this summer or ever.

                              Just trying to see if chuckchuck has anything positive to say today.

                              Like what sort of variety hes on today and what the yields like in his neck of the woods.
