He pretty much explains why earth is a long way from runaway greenhouse warming like Venus is and also explains the benefit that CO2 emissions bring in such as higher crop yields so I guess ~1000 ppm of CO2 is ideal for plant life ... (need to at least double the CO2 concentration)

Sure, there are probably some doom-mongerers that spread horror stories about how we'll turn to Venus if we don't stop (we won't in the next several dozens of millions of years), but that has never been the threat from climate change. Besides, ideal for plant life doesn't mean ideal for human life, or life overall.
