It turns out that the benefits of rising carbon dioxide concentrations offset the expected agricultural damage from warming. [emphasis, links added]
In 2023, U.S. EPA (Environmental Protection Agency) activists skeptically raised the “social cost of carbon” (SCC), which was due to the inability to support the forecast of agricultural deterioration, and thus CO2 increased crop yields and subsequent The climate has caused a decline in crop yields.
The 500% SCC hike is based on a biased negative model that ignores the obvious positive crop yield benefits of rising CO2 concentrations.
EPA discovers analysis of EPA relying on its suspicious accounting in modeling paper (Moore et al., 2017 and Challinor et al., 2014) Multiple factors that tend to be ignored in the agricultural process (For example, precipitation changes, changes in atmospheric carbon dioxide, water utilization efficiency, adaptation, technology…) and mainly focus on the assumed negative effects of warm climates.
But now a new analysis has been conducted no Ignore all other factors, especially the very beneficial effects of carbon dioxide fertilization – Any future warming, even when it reaches 5°C, will still have a net positive impact on crop yields.
“The benefits of CO2 fertilization and adaptability completely offset the negative effects of temperature.”
“These coefficients indicate that the atmospheric concentration of carbon dioxide doubled from 280 ppm and resulted in 3°C warming, with an average of -14.7% (due to warming) plus 16.8% (due to CO2 fertilization) net effect of + 2.1%. ”
“However, after combining new available data, the changes in the conclusions have resulted in positive global average yield growth for all crop types under CO2-induced warming, even if the warming is 5°C.”
