evidence: Skeptical Science categorizes this claim as "incorrect." They explain that although Hansen’s prediction of a global temperature increase was higher than the actual warming observed, this discrepancy stems from his use of a high climate sensitivity parameter. Had Hansen employed the currently accepted value of approximately 3°C warming for a doubling of atmospheric CO2, his model would have more accurately projected the observed global warming. [...] Such claims, which mix false (frequency and intensity of droughts) and indisputable (CO2 and water efficiency of plants) elements, are typical of climate denier rhetoric. This tactic can cause confusion and obscure the overall understanding of climate change impacts. It underscores the importance of thorough and nuanced analysis when evaluating and categorizing climate-related claims. [...] Appendix F Overview Skeptical Science claims
