During the last glacial maxima, the ppm of CO2 dropped to 180. Photosynthesis shuts down between 150-180 ppm CO2, meaning no vegetation. We currently sit around 420 ppm. We run green houses at 800-1200 ppm.
Point being, global warming and higher CO2 levels are beneficial for this planet. We’ve seen 15% of the globes surface begin to green over the last 25 years which is roughly the size of the US. During the years of the building of the great cathedrals in Europe, average temperatures were 3 to 4 degrees fahrenheit warmer than we see today. Behind that came the little ice age which brought on the black plague and famine as crops failed and disease spread resulting in the death of 1/3-1/2 of the population of Europe.
Do we have an impact on climate? There is no doubt. Agriculture, mining, transportation all have an effect. How “destructive” it is, that’s where the real debate is.
Global warming isn’t this terrible demon it’s been made to be, global cooling is. When the earth cools, we won’t be able to feed ourselves, let alone our livestock. You can fill all the highways of the world with electric vehicles. It wont save us. Our best hope is to embrace our technology. How do we stop solar flares or meteor or comet impacts? Volcanos can send us back to the stone age as well if the eruption is catastrophic enough, but look to the skies if you want to see where our doom will most likely come from. The ancients obsessed over the stars, but now due to light pollution, our heads stay down to the floor. Trust the real science and real numbers, not the ones with things to profit, or those dependent upon “donations” to continue their “research”.
