Hydrogen gas does exist in Earth's atmosphere as a recognized trace gas with an active global budget involving various sources, sinks, and atmospheric reactions.

The analysis

The claim states that hydrogen gas does not exist in significant quantities in Earth's atmosphere. However, atmospheric science literature (such as papers [5] and [9]) extensively studies the global tropospheric hydrogen (H₂) budget, detailing continuous production, sinks, and significant trace quantities (tens of teragrams per year cycled through the atmosphere). Therefore, the claim is refuted by established atmospheric research showing a substantial, active atmospheric hydrogen cycle.

Paper [5] examines the global tropospheric budget of hydrogen gas (H₂), estimating annual atmospheric production of 37–60 Tg and losses of 15–30 Tg, demonstrating that significant quantities of hydrogen gas are actively present and cycled in Earth's atmosphere.
