An entertaining read, but I think you are unduly negative. CO2 is released from fossil fuels which are themselves a naturally occurring Carbon sequestration from ancient forests that grew in CO2 concentrations of 1000 to 2000 ppm 100 million years ago. Coal, Gas and Oil are just nature’s carbon batteries storing aeons-old solar energy. By releasing the energy to fuel our industrialised society, we return the CO2 to nature’s Carbon Cycle, where it belongs. This is good for both crops and nature: this is not a theory, it’s an observable fact.
Stop scaring yourself: the planet was 3 degrees Celcius warmer only 80,000 years ago in the last interglacial, and the world teemed with life, with rain-forests covering the Sahara and central Australia. Global Warming is not to be feared: it is to be welcomed.

It is inevitable in any case, CO2 emissions may be speeding it up, but it was always going to happen as the last ice age finally comes to an end.
We should prepare for a warmer, wetter world, and for the slow rise of the oceans to their former levels. We may lose some coastal land over the next 8000 years, but will be compensated for this by the return of former deserts to arable land. Our remote descendants will consider their world to be the natural order of things and our era to be a frozen hell in their distant past.
