Fmr. Harvard U. Physicist Dr. Lubos Motl: ‘Why we should work hard to raise the CO2 concentration’: ‘CO2 is primarily plant food while its other implications for Nature are negligible in comparison. Humanitarian orgs should work hard to help mankind to increase the CO2 concentration’
'CO2 is the key compound that plants need to grow – and, indirectly, that every organism needs to get the food at the end. See, for example, the hysterical reactions by Climate Science Watch, the lousy and badly biased astronomer Phil Plait, anti-Fox-News attack dog organization Media Matters for America, and many others. Many of them seem to literally say that it's been disproven that plants need CO2 to grow; I kid you not'
