Well argued, though personally I prefer to match a spinkling of hope combined with a whole lot of action to this defining theme of our lives. We absolutely can make the changes necessary and there's still time to taper emissions to avoid catastrophe and the worst climate scenarios. Yes that does mean some behavior change for individuals though governments and companies give us the scale of impact. The time we have to act is reducing, but until it's gone there is hope. Like large companies and governments building roadmaps now, what can you do to reduce your emissions and those around you? It all matters, it all makes a difference ;)
