CO2 and Crops: NAS vs. Science

By David Burton – Re-Blogged From WUWT

One of the most pernicious examples of disinformation promoted by the Climate Industry is the claim that manmade climate change from CO2 emissions threatens agriculture and “food security.” That’s the exact opposite of the truth. CO2 is “plant fertilizer,” and hundreds of agricultural studies have shown that higher CO2 levels are dramatically beneficial for agriculture, to levels far above what we can ever hope for outdoors.

Most plants grow best with daytime atmospheric CO2 of at least about 1500 ppmv. That’s about what CO2 levels are thought to have averaged during the Cretaceous. It’s 1090 ppmv higher than the current average outdoor level of about 410 ppmv.

In other words, most plants would grow best if CO2 levels were increased by more than eight times the measly 130 ppmv by which mankind has managed to increase CO2 levels since the “pre-industrial” Little Ice Age. (Levels even higher than that wouldn’t hurt plants, but they wouldn’t help much, either.)

ICCC-10: Due to The Heartland Institute’s Tenth International Conference on Climate Change (ICCC-10), June 11 and 12, this week’s TWTW will be brief. The conference was co-sponsored by, among others, SEPP and the Virginia Scientists and Engineers for Energy and Environment (VA-SEEE), Next week’s TWTW will include material that was overlooked this week due to time constraints. The conference was sold out about one week in advance. Videos of the keynote speeches and the panel sessions are available at: http://climateconference.heartland.org/. It is our understanding that high resolution videos will be available shortly.
