In Canada, our area of burn has quadrupled since the 1970s. My colleagues and I attribute this to human-caused climate change. It's not just fire; it's flooding and a rise in sea levels. We are changing the climate because of our human activities, primarily greenhouse gases. Until we do something as a society, a global society of people, as communities, states, provinces, territories....
We have to solve this problem. The scary thing is that even if we stop producing greenhouse gases today, we'll continue to warm for 20 or 30 years. A warmer world means more disasters.
