No one has yet said the first hurricane, first forest fire, first drought, us the one caused by climate change. We have had them for ages. Only now have they become due to climate change. Maybe that's because I am older and have a longer memory. When will we know we have done enough? Spent enough? What's the end game? No carbon. When was the last occurrence of that? Get a grip guy the world (and trout) are not ending.
