Do we drag to doomsday as scientists find a drastic drop in oxygen levels? While capably analysing minutely the augmenting changes in the very brightness of the Sun and the corresponding plunge in the carbon dioxide levels, the irascible researchers try to maintain that less carbon dioxide means fewer photosynthesizing organisms such as plants, which would result in giving less oxygen. The comparative decline in oxygen is exceptionally drastic, they felt.
Scientists anticipating the fear of a sudden doomsday scenario pointed out in their profoundly studied research paper that the atmospheric deoxygenation along with the atmospheric O2 dropping out snappily to levels seemingly hints at the Archean Earth. This will most presumably be later turned on before the genesis of moist greenhouse conditions in Earth’s climate system and before the comprehensive loss of surface water from the atmosphere, they said.
Oxygen constitutes about 21 per cent of the Earth’s atmosphere and plays a significant role in the survival of countless species. Yet this was not constantly the possibility. The conditions were broadly different around 4.5 billion years ago when the planet was thought to have formed. Carbon dioxide, methane and water vapour were chiefly dominant in Earth’s atmosphere. Scientists have also predicted that in future, Earth’s atmosphere will revert to one that stands inadequate in oxygen.
