Study Claims Climate Change Has Reduced Global Wheat Yields by 10%

A recent study published in the Proceedings of the National Academy of Sciences claims that global wheat yields are approximately 10% lower due to the effects of climate change over the past 50 years. The research analyzed data on climate conditions and crop yields, focusing on wheat and other major crops. It highlights how rising temperatures and droughts have impacted agricultural productivity in key regions, including parts of Europe, China, and Russia. Critics, however, question the study's methodology and conclusions. They point out that the claimed "climate change effect" does not align with observed trends, which show no significant worsening of yield losses over time. Additionally, they argue that the study fails to account for the benefits of fossil fuels, such as improved mechanization, transportation, and refrigeration, which have significantly enhanced agricultural productivity. The study's findings have been used by organizations like Carbon Brief to promote climate alarmism. However, global wheat production remains near record highs, according to the UN Food and Agriculture Organisation. This raises doubts about the severity of the claimed impact of climate change on crop yields. The research also faces skepticism over its funding sources. Carbon Brief, a prominent climate advocacy group, receives substantial financial support from left-wing foundations, raising concerns about potential bias in its reporting and research.
