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.)

Remember when climate alarmists told us global warming was going to kill the U.S. corn crop? Never mind.

By Anthony Watts – Re-Blogged From WUWT

You may remember seeing scare stories like these in the media.
Claim: Climate Change will Cause a Global Corn Crop Failure 

Global Warming Will Cut Crop Yields – Assuming No Adaption

Reality bites in two ways; 1. Actual data shows yield increases, and 2. New study says warming has actually helped corn yields.

Global Warming & Crop Yields

By Eric Worrall – Re-Blogged From http://www.WattsUpWithThat.com

A PNAS study claims that crop yields will fall by up to 7% for each degree celsius of global warming, assuming no CO2 fertilisation and no adaption measures.

Climate change will cut crop yields: study

August 15, 2017

Climate change will have a negative effect on key crops such as wheat, rice, and maize, according to a major scientific report out Tuesday that reviewed 70 prior studies on global warming and agriculture.

Heartland Climate Change Conference

This was my first climate change conference and I had a great time. To hear the full talk by any of the speakers go to the Heartland.Org site here.

The most memorable statement is from Myron Ebell. Three U.S. elections “have turned on climate issues.” These are 2000, 2010, and 2016. In 2000 Al Gore lost because he lost West Virginia. This “was due entirely because someone named Buck Harless put,” in every voter’s mailbox a study he commissioned showing the effect on West Virginia’s coal industry and economy of Al Gore’s proposed policies. The 2010 election was turned by the Waxman-Markey cap-and-trade bill, which caused the House Democrats to lose 20 seats and making the House of Representatives Republican. Finally, in 2016, climate change and the fossil fuel industry were explicit issues and Clinton and Trump were on opposite sides. The pro-fossil fuel side won the key fossil fuel states of West Virginia, Pennsylvania, Ohio, Tennessee and Kentucky.
