Publisher's Synopsis
In this book Kate and Tom discover that there is a terrible disaster in Canada caused by climate change. Warmer temperature has enabled the pine beetle to overwhelm and kill the pine trees in the Jasper National Park. The trees burn easily when wildfires start. The soot from the fires then travels into the ice in the Athabasca glacier which warms and melts. This is a feedback system that is destroying both the national park and glacier adversely. The system has reached a tipping point.
