Title and Executive Summary
IPCC AR6 says AMOC collapse very unlikely before 2100
The Net-Zero / Carbon-Credit / Climate-Finance Architecture:
Ditlevsen 2023, van Westen 2024, Drijfhout et al. 2025 argue AMOC collapse plausible mid-century
The Net-Zero / Carbon-Credit / Climate-Finance Architecture:
IPCC AR6 assessed ZEC central estimate = 0
The Net-Zero / Carbon-Credit / Climate-Finance Architecture:
Methane's GWP-20 is ~84–87
CANOPTICON Second-Pass Stress-Test: The Net-Zero / Carbon-Fi
ECS is probably in the 2.5–4°C IPCC range
CANOPTICON Second-Pass Stress-Test: The Net-Zero / Carbon-Fi
the lower end of the ECS range cannot be excluded on observational-constraint grounds
CANOPTICON Second-Pass Stress-Test: The Net-Zero / Carbon-Fi
The IPCC AR6 WGI 2020 starting budget of 500 GtCO₂ for a 50% chance of 1.5°C
Title and Executive Summary
Approximately 75% of the IPCC AR6 WGI 2020 starting budget was spent in the five years from 2020 to 2024

These are things people say about IPCC that aren't settled fact — each one attributed to who's actually claiming it, so a claim never quietly passes as established just because it showed up in a document. Weigh it yourself.
"nuclear is a legitimate mitigation pathway"
"integrated assessment models systematically obscured the scale of assumed negative emissions."
"IPCC has underestimated aerosol forcing and claim +0.5 W/m²"
"CDR scaling is speculative"
