Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.
Thanks to the Montreal Protocol, ozone-depleting chemicals have declined and the ozone hole appears to be on the mend. Yet, despite its success, something is not … quite … right.

As the complex story of climate change unfolds, many of the endings are grim. But there are exceptions. Predictions that the lowest-oxygen environments in the ocean would get worse may not come to pass.
Evolution of the first burrowing animals may have played a major role in stabilizing the Earth's oxygen reservoir, according to a new study in Nature Geoscience.
Oxygen therapy is known as the administration of oxygen as a medical intervention. It is indicated in patients whose oxygen supply is compromised due to both acute and chronic health conditions and can be administered in many different ways. Oxygen therapy can be administered virtually wherever the patient is. Most commonly, oxygen is delivered to patients in an ambulance, hospital, or doctor’s office. These medical facilities carry oxygen in the form of a compressed gas. It is stored...
The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
