New in this version (DE + EN parallel rewrite): Integration of Paper 8 v3 findings. Two forest-water mechanisms are now quantified as Northern-Hemisphere-specific contributors: the Amazon-jet-stream cascade (PCMCI+, ~16 % of the 2003–2024 warming-divergence increment, directionally proven) and the Central European evapotranspiration tipping point (three-region regression + 75-year ERA5 reconstruction, ~57 % of the increment, currently dominant magnitude). Both share the same physics — root-zone water buffer feeds stomatal regulation feeds surface cooling — but operate in different phases of the same tipping trajectory. Europe is quantitatively co-cause of accelerated NH warming, not only victim. Groundwater restoration identified as the currently dominant actionable lever for European climate policy.
Plain-language pass: technical acronyms (NH/SH, STJ, ET, BVOC, CCN, OLS, GHG) systematically replaced by German/English readable equivalents. §11 consolidated — three overlapping subsections reduced to two (context + regional attribution). Overclaimed numbers corrected (r=−0.45 partial for West Africa → Europe, not "β=−0.40 directionally attributed"). All 30.2 % / 69.8 % rounded to ~30 % / ~70 % with ±5–8 % CI.
Retained content: four-mechanism forest cooling table (now five with STJ stabilisation), tipping-point regional status, moisture-network topology, REDD+ audit (West 2023, Trencher 2024, Tang 2025), satellite auto-monitorability argument, cropland-mycorrhiza decoupling (EU 190–400 Mt CO₂eq/yr potential via AMF + no-till), Hannover-Fuhrberg riparian-forest case study. Target audience: EU Parliament, Bundestag, UNFCCC delegations.
Zwei Sprachen (deutsches Original + englische Übersetzung). Zwei Wald-Wasser-Mechanismen jetzt quantitativ aufgezeigt: Amazonas-Jetstream-Kaskade (~16 % des 2003–2024-Divergenzzuwachses) und mitteleuropäischer Verdunstungs-Kipppunkt (~57 %, derzeit dominant). Grundwasser-Restoration als aktuell wichtigster Klimaschutz-Hebel für Europa.
