  1. Dangerous propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.
