Summary: A report from the National Technical University of Athens finds no evidence of human fossil fuel influence in CO₂ emissions over the past 40 years, refuting UN global warming claims. CO₂ isotope signatures unchanged since the Little Ice Age (16th-19th centuries), with human impacts indistinguishable from natural factors. Proxy data show modern warming mirrors earlier periods like the Medieval Warm Period (1000 AD), Roman Climate Optimum (1st centuries BC/AD), Minoan Optimum (1500 BC), and Holocene cycles.
Recent warming expanded the biosphere, boosting productivity, CO₂ levels, and Earth’s greening. Greenhouse effect stable due to water vapor dominance; human CO₂ plays minor, barely discernible role. Confirms biosphere’s carbon cycle as primary driver.
