Sure, we're on course for disaster. But pretending like there is a single tipping point and that we're Doomed (doomed, I say!) anyway, is just a convenient excuse to wallow in hopelessness and inaction. The truth is that we're still making things worse by the day, and every kilo of CO2 saved helps slow down the speed of the disaster. And those little efforts by folks like us, might still make the difference between 1 billion dead or 1.1 billion dead.
