No. It is the title of a book I read some time back. I thought the projections in the book were absurd, but the reality is that AGW HAS been accelerating faster than the worst case scenarios.
I googled "tons per year of CO2 by humans", and it verified the max was 281 PPM in the past 650,000 yrs. of ice core data. Humans put out 150 times the average volcanic output of CO2, knew that, too. The annual amount put out by humans of CO2 is now 24 Billion tons. The planting of 7 billion trees is laudable, but at a ton each of CO2 sequestration in their lifetime, it is obviously much lower than the human output. We can't plant 170 times that many trees, so the vast reduction needed must come from stopping fossil fuel use 70 to 80% and totally stopping slash and burn and swamp draining agriculture. All within a decade, or the eventual temps in 2050 will be enough for the ocean CH4 hydrate releases to go self-sustaining. Then "thermageddon", after the couple hundred years it takes for the oceans to warm and "turn over" the CH4. There probably won't be many people left by then.
I sure hope the powers that be in Copenhagen take all of this into account. Most people will scream and cry when their fossil fuels and traditional ecological waste are vastly reduced. Certainly, the world economy must change to steady state from growth only, and that change will also be painful. To start having to pay true costs will be very tough. So will having to pay for the mistakes of others now dead. The fossil fuel addiction will be very hard to kick.
