In addition to the public sightings, the team hung traps at 24 locations across the country, luring the insects by the smell of carbon dioxide which mimics human breath.

It is this material that can be used as a proxy for the amount of planet-warming carbon dioxide stored.

However, a study Havenith published last week in Communications Psychology found these altered states of consciousness achieved through high-ventilation breathwork were directly associated with reduced levels of carbon dioxide, presumably as a result of hyperventilation.

As carbon dioxide and other greenhouse gasses build up in the dense lower atmosphere, they absorb heat and keep it trapped there.

Hydrogen is a promising source of energy that produces water vapor instead of carbon dioxide as its byproduct, which proponents say could be used to power hard-to-decarbonize industries such as steel production, manufacturing and transportation.
