Of course it is. Crap like "tipping point" of CO2 , not mentionong that water vapor accounts for 90 to 95% of the greenhouse effect, forgetting to mention that during the Dinasauer period the CO2 was at 4,000PPM, and today, at aboout 380 PPM. aT 4000 ppm, THERE WAS no runaway greenhouse effect. Remember, the CO2 effect is LOGRYMIC not GEOMETRIC! As onlY certain wavelengths convert to IR, as they are converted, there is less and less to concert, so the effect tapers off. It is not "catistrophic"!
Further, you can observe yourself that the oceans have not risen as predicted, only a tiny fraction of sealevel rise has been actually observes, less than 10% of predicted. FURTHER, evidence at the poles indicated that in the glaciation before this retreat, the glaciers were essentially gone, both poles. So, somewhere on Earth, in fact all over earth, there should be the remains of beaches MUCH higher on the land that date abt 300,000 years ago. There are NONE.
Anyway, IT GOES ON AND ON. oF COURSE THERE IS CLIMATE CHANGE. But the idea that in 200 years of industrialization out of 4.5 BILLION years of ever changing climates, we're going to either save or ruin the Earth is, well, just silly.
