NASA, NOAA Rank 2024 Ozone Hole as 7th-Smallest Since Recovery Began – NASA

Healing continues in the atmosphere over the Antarctic: a hole that opens annually in the ozone layer over Earth’s southern pole was relatively small in 2024 compared to other years. Scientists with NASA and the National Oceanic and Atmospheric Administration (NOAA) project the ozone layer could fully recover by 2066. During the peak of ozone … Read more

Ozone heating Earth more than previously thought, says study

The ozone layer may be heating the Earth’s atmosphere more than previously thought by weakening one of our planet’s most important cooling mechanisms, according to a study. The researchers found that changes to ozone levels in the upper and lower atmosphere were responsible for almost a third of the warming seen in ocean waters bordering … Read more

Climate change: Wildfire smoke destroys ozone layer, new study finds

However, the damage was temporary and the ozone levels returned to pre-wildfire levels as the smoke dissipated from the stratosphere. Smoke from wildfires, which have become a common phenomenon across the world, can destroy the Earth’s ozone layer, a new study has found. The ozone shield in the Earth’s stratosphere absorbs the sun’s ultraviolet rays. … Read more

International Day for Preservation of Ozone Layer: Significance of the most successful global climate treaty

Several common chemicals are known to cause severe damage to the ozone layer. (UN) As climate change and global warming take centre stage, a less heralded hero of the Earth’s atmosphere quietly battles on. A thin layer of gas surrounding the Earth, the ozone layer protects the planet from the sun’s harmful rays, thus preserving … Read more
