Nicola Scafetta discusses his book, "The Frontier of Climate Science," a review based on about 650 peer‑reviewed papers arguing that IPCC global climate models have serious limitations because they fail to capture multi‑scale natural variability (oceanic, solar, astronomical, and tidal cycles). He says model claims that nearly all warming since 1850 is anthropogenic are not experimentally validated, climate sensitivity remains highly uncertain, and many models run too hot, with possible surface-record warm bias from urban heat islands. He cites past warm periods and correlations between climate and solar/cosmic-ray proxies, proposes empirical/semi‑empirical cycle-based modeling, and concludes warming risk is moderate, SSP2 could meet Paris targets, net zero is unnecessary, and adaptation should be prioritized.
