Ukratko, nekidan su znanstvenici napokon koristili AI za neke smislene stvari (a ne za pisanje pjesmica i dopisa) i dokazali empiricki da je sve ovo sa ljudskim utjecajem na klimatske promjene totalna idiotarija i CO2 footprint je zanemariv u usporedbi sa onim pravim uzrocima klimatskih promjena, a koji su, ajmo to tako reci, galakticke i planetarne naravi... Znaci, varijacije suncevog zracenja, dinamika oceana i slicno...

Dovoljno je proletiti kroz poglavlje 5. Conclusion u ovom dokumentu - https://scienceofclimatechange.org/w...eview-V5-1.pdf, a mozete i koristiti statisticko pogadjalo da vam napravi summary dokumenta i prevede sve na hrvatski...


The anthropogenic CO₂-Global Warming hypothesis, as articulated by the Intergovernmental Panel on Climate Change (IPCC) and supported by researchers such as Mann, Schmidt, and Hausfather, lacks robust empirical support when subjected to rigorous scrutiny. This analysis integrates unadjusted observational data and recent peer-reviewed studies to demonstrate that the assertion of human CO₂ emissions as the primary driver of climate variability since 1750 is not substantiated. Instead, natural processes—including temperature feedbacks, solar variability, and oceanic dynamics—provide a more consistent explanation for observed trends.

A key finding is the minimal contribution of anthropogenic CO₂ emissions to the global carbon cycle. Human emissions, quantified at 10 GtC per year or approximately 4% of the 230 GtC annual flux, are significantly outweighed by natural exchanges—80 GtC from oceanic processes and 140 GtC from terrestrial respiration and photosynthesis [7]. Koutsoyiannis (2024) [7] provide isotopic evidence, showing a stable δ13C net input signature of approximately -13‰ over two centuries, resulting in a 1‰ shift in the δ13C atmospheric content since 1980 despite an 80 ppm CO₂ increase [7, 12]. This limited deviation, relative to the -28‰ fossil fuel signature, indicates that natural fluxes predominantly govern atmospheric composition, a conclusion supported by the 2020 COVID-19 lockdown data, where a 7% reduction from the 2019 human emissions (0.7 GtC) produced no detectable change in Mauna Loa’s CO₂ curve [22]. Koutsoyiannis (2024) [39] estimate a CO₂ residence time of 3.5 to 4 years via a mass balance approach (230 GtC/year flux), contrasting with the IPCC’s model-based 120-year (or more) projection [38, 39]. Harde’s studies (2017, 2019, 2021) [11, 12, 40] reinforce this, deriving residence times of 3 to 4 years, collectively challenging the hypothesis of significant long-term human CO₂ retention.
