Levels of molecular hydrogen (H₂) in the atmosphere have surged in modern times due to human activity, according to new research.

When scientists analyzed air samples trapped in drilled cores of Antarctica’s ice, they found atmospheric hydrogen had increased 70 percent over the course of the 20th century.https://ee995e3b7d42c2062ca2efcd673d1e90.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

Even as recent air pollution laws have sought to curb fossil fuel emissions, hydrogen emissions have continued to surge with no signs of slowing down. And there’s a chance that leakage is to blame.

Molecular hydrogen is a natural component of our atmosphere due to the breakdown of formaldehyde, but it is also a byproduct of fossil fuel combustion, especially from automobile exhaust, and biomass burning.

While hydrogen doesn’t trap heat in the atmosphere on its own, it canindirectly impactthe distribution of methane andozone. After carbon dioxide, these are the…
