“Climate is always changing,” he said. “You should never expect climate at an equilibrium, and history shows it’s not.”
More CO2 means better crops and forests, Steward says, but not necessarily a warmer planet since other factors play a bigger role in heating the planet.
“This relates directly to the food supply,” he said. “Green is good, and CO2 is very green.”
CO2 boosts plant growth, making them larger, faster-growing and more drought tolerant with better roots. Steward calls that good news in a world with a growing population.
“When you’re deciding what ought to be done, think about what this could do for mankind,” he said.
Taking CO2 back to pre-industrial levels would degrade habitats and push people into starvation, Steward said.
“CO2 is not a pollutant. It’s the stuff of life. I can’t find anything that’s not beneficial,” he said. “This comes from thousands of studies – mainly from the agricultural community, and these are not casual observers.”
Spending billions and enacting draconian restrictions to fight a “pollutant” that’s not a pollutant isn’t helping anyone, he said.
“If we let our factories continue to manufacture, that’s not necessarily bad and might be good,” he said. “We (pro-CO2 groups) are greener than all the green organizations lobbying to reduce CO2.”
