Good News: Our Grandchildren Will Starve, Not Our Children

"So when Hansen and colleagues write that climate sensitivity for doubled CO2 is 4.5°C, and that sensitivity as low as 3°C is excluded with greater than 99 percent confidence — they stop there. Slice completed. No return to the whole. No wonder the media shrugs. So what.
Here's the whole.
* Doubling CO2 means going from 280ppm to 560ppm. We're at 420ppm now. At current trajectory — roughly 40ppm additional per decade — we hit 560ppm around 2055. That's 4.5°C by roughly 2060. Not 2100. 2060. Hansen also shows Earth's albedo has already darkened by 0.5%, an extra 1.7 W/m² of absorbed solar energy. The system is already running hotter than the models admit.
* Time doesn't stop at 2060. At those temperatures, natural feedbacks (clouds, ice, permafrost) accelerate. There is no equilibrium, only continuation.
*Above 5°C, effective human extinction is locked in. We are on that path.
*Facts alone don't move humans. Emotion does. We are human, after all. So the headline that would actually communicate the whole truth? "We are all going to die, you fucking idiots.""
