For me, this book was fascinating, gripping, and I learned a lot. Of course, we hear about CO2 levels all the time but really don't understand what it means. At least I did not understand what it meant.
This book put it in perspective as it made a huge forest fire in Alberta, Canada, which burned down almost all of Fort McMurray (a place located about 100 miles south of the Arctic Circle) in 2016 the compelling example of what's NOT normal now. Ironically, Fort McMurray is a center for extracting oil from sand (there's terms for all this). This book is powerful in showing how an out of control wildfire, unlike wildfires of the past, fueled by hotter temperatures caused by added CO2 in atmosphere caused by humans' dependence on oil is affecting many areas and not just northern Alberta. Reading something like this can be overwhelming because as individuals, it's a helpless feeling. Still it's better to understand what is happening and why. My only disappointment with this book is no real options were offered such as coming up with methods (gosh, I still believe in science) in reduce CO2 in the atmosphere other than reducing the use of petroleum and oil. This is the world we live in now and I think it's important to understand that. My rating is 5 stars.
