Study Destroys Basis Of EPA’s Climate Regulations

“The new findings aren’t just a minor correction to the scientific record, they are a reversal of dangerous conclusions drawn from sloppy - perhaps even fraudulent- analyses. Everything we’ve been told about climate change and food security is wrong.”
“In 2014, a widely cited meta-analysis of crop-model studies claimed that a warming climate would slash global crop yields, an assertion that fed into subsequent models that influenced the Biden EPA’s social cost of carbon hike.”
McKittrick, undeterred by what had become climate orthodoxy, dug deeper. By revisiting the source material, he recovered 360 additional records, bringing the record to 1,222 - about a 40% increase in usable data.”
The additional information showed “positive average output gains for all crop types across the warming scenarios even up to 5 degrees Celsius” - a temperature jump far beyond warming predictions of the U.N.’s International Panel on Climate Change. This isn’t cherry picking; it’s what happens when the full scope of evidence is examined.”
“Moreover, plants are not to frail for a warming world. They’re built to thrive in the contemporary temperatures of the 20th and 21st centuries.”
“Most crops fall into two categories: C3 and C4 plants, so named to reflect their different photosynthetic processes. C3 crops such as wheat, rice and soybeans, flourish in elevated CO2 conditions characteristic of the 21st century.”
“Higher levels of CO2 act like a supercharger, boosting photosynthesis and water use efficiency. Studies have long shown that CO2 enrichment in greenhouses can increase C3 yields by 20% to 40%. C4 crops like - corn and sorghum - are less responsive to CO2, but do well in hotter, drier conditions.”
““If over the next 100-200 years, yields of all crop types increase, it does not stand to reason that a global trade model could generate global welfare reductions,” writes McKittrick in his closing remarks.”
“The McKittrick study is consistent with an extensive historical record that documents human flourishing during earlier era’s warmer than today. The Minoan Warm Period 3,000 years ago and the Roman Warm Period and the Medieval Warm Periods that followed are examples.”
“Unfortunately, the United Nations International Panel on Climate Change - relied on by many as the standard bearer for information on climate change - favors adherence to climate dogma over rigorous scientific inquiry.” |
