The Wall Street Journals’ bloggers have shared their pessimism about rising global GHG emissions. Here is their piece’s last paragraph;
“But the fact remains that all that lies between us and “a long-term global temperature increase of more than 3.5 Celsuis with dangerous consequences for the global environment and human welfare,” is a hoped-for technological miracle.”
But, for those of you who are cautiously optimistic about our future, there are some things you can point to. California’s ARB will roll out its Cap & Trade program soon. I believe in the “green guinea pig” effect. California’s regulatory effort will provide a field experiment that will teach us whether “negative NPV” carbon reduction investments truly exist. McKinsey’s optimism will have its day in court.
Also, don’t forget about adaptation! When you see a punch coming at your face, do you duck or do you take it on the chin? We can (and we will) see the punch coming. UPDATE: Here are two examples from Texas: Example #1 and Example #2 on cattle migration.
