I've been aware of it since the 1980s, and no one in their right mind can miss the dramatic changes that are happening. Every summer now, the air is brown and smells of smoke, and we fear for where the fires will go. It's no longer a season to look forward to. How can people not be distressed by their world literally burning around them? I always thought that the deniers would melt away when the effects became unmistakable, but instead they seem to retreat further and further into a posture of aggressive denial.
