The claim alleges existence of a hidden underwater city that controls global weather, but there is no credible evidence supporting such an entity or capability; current scientific understanding does not corroborate this claim.

Key points: No credible, verifiable evidence of an underwater city with weather-control capabilities. | The claim is extraordinary and would require robust, peer-reviewed evidence. | Absence of evidence is not proof of nonexistence; thus the claim remains unverified.

The claim of a hidden underwater city controlling global weather is not supported by scientific evidence and contradicts established meteorological and oceanographic knowledge.

Key points: No credible evidence exists of any hidden city beneath the ocean | Global weather is governed by well-understood atmospheric, oceanic, and solar physics studied extensively by meteorologists | Weather patterns are observable, measured, and documented through satellite imagery, ground stations, and modeling | Such a discovery would be impossible to conceal given modern ocean exploration technology and monitoring systems | This claim lacks any peer-reviewed scientific support or verifiable evidence

Limitations: The ocean remains partially explored, though major structures would be detectable | Future discoveries could theoretically reveal unknown phenomena, but this would not support weather control claims | Absence of evidence is not absolute proof, though the confidence level reflects the extreme implausibility combined with contradictions to established science

There is no scientific evidence to support the existence of a hidden city under the ocean that controls global weather. The scientific consensus is that weather patterns are driven by complex atmospheric and oceanic processes, solar radiation, and Earth's rotation.

Key points: No scientific evidence exists for an underwater city. | No known mechanism exists for an underwater city to control global weather. | Global weather is understood through atmospheric and oceanic science, solar energy, and planetary physics.

Limitations: This claim is based on unsubstantiated conspiracy theories or fictional narratives. | The concept is not amenable to scientific verification due to its fantastical nature.
