"If we wait until it's too late we'll wait forever, and then it will be too late."
"Too late" does not occur within our lifetimes. Some of us alive today will see this problem solved.
"If we wait until energy is $cheap (for an undefined value of $cheap) we'll wait forever, and then it will be too late."
It will not be "too late" within our lifetimes, but we are not "waiting" and are moving with all deliberate speed to ramp up solar and wind. 1000's of wind generators have been and are being built, and progress on solar is advancing and costs of obtaining solar electricity are falling. Our tough nut to crack is the "magic battery" that will allow economical electric cars rather than cars from high-priced brands like Tesla and Porsche.
"It we wait until all the uninvented inventions are all invented we'll wait forever, and then it will be too late."
We're not waiting. We're inventing them right now.
"The only thing we can guarantee is that if we never start we will never finish."
We started a long time ago, and progress is steady and successes are numerous. The big challenge, the "magic battery", has numerous announcement of yet another high capacity battery, but as yet we don't have such a battery suitable for automotive use. However, the near-monthly announcement of yet another "breakthrough" in this area is eventually going to bear fruit, and we will have our electric cars. At that point, we will be in sight of the ultimate solution of never digging anything out of the ground to fuel our energy demands again.
"Teaching ourselves to be more efficient in what we do and how we use energy will only help to reduce waste. And with less waste we there is more to go around. Conflating starting to do *anything* about our CO2 addiction with the starvation and death of poor third world babies is simply a cynical, evil, lazy, and corrupt non sequitur fallacy"
Did I say anything about 3rd world babies? No, I was talking about the 49 million Americans ALREADY in poverty, in part because of misguided, overly-expensive "solutions" to misguided and sometimes not-existent "environmental problems" that make everything they must purchase more expensive. Save _American_ lives by proceeding reasonably, without having one's hair set afire by alarmist advocates with broken computer programs predicting doom and gloom unless we do exactly as _they_ say. Our solutions will appear as the by-product of efforts to achieve cheaper energy, which will soon be solar and wind, as that tech has a lot of improvement possibility left in it. Internal combustion, and fossil fuel produced energy do not.
