On an earth system time scale, we are ringing a bell with a sledge hammer, and we are only hearing the very first vibrations. Most people do not realize that even the fact that there is a measurable temperature increase over the globe in a single year signals monumental changes. Petajoules and Exajoules are foreign concepts. I understand the numbers, but I doubt I grasp the significance.
I have looked at everything from concentration-to-temperature-increase times, to feedbacks, to the sheer magnitude of what CCS or BECCS would involve, even if it were viable. And then there is CO2 persistence.
Granted, I am a cynical SOB, but I also have a fairly good handle on math, which means I don't shy away from reality.
Isn't it about time that we stop using seemingly obligatory phrases like:
"Imagine if we do not accelerate efforts to quickly drop emissions. "?
