Ozone (O3) is a molecule made up of three atoms of Oxygen (O), and is mostly found in the strato- sphere, where it protects us from the Sun’s harmful ultraviolet (UV) radiation. Although it represents only a tiny fraction of the Atmosphere, ozone is crucial for life on Earth. The stratospheric ozone layer forms a … Read more

The Greenhouse Effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s Atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. It is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a … Read more
The Rise and Fall of Chlorofluorocarbons: A Story of Environmental Triumph and Ongoing Challenges Chlorofluorocarbons (CFCs) are a group of synthetic organic compounds that were once widely used in various applications, from refrigerants and aerosols to foam blowing agents and cleaning solvents. Their seemingly miraculous properties â non-flammability, chemical stability, and low toxicity â made … Read more
The Thinning Veil: A Comprehensive Look at Ozone Depletion The Earth’s atmosphere is a delicate shield, protecting life from the harsh radiation of the sun. Within this shield lies the ozone layer, a crucial component that absorbs harmful ultraviolet (UV) radiation, preventing it from reaching the surface and causing widespread damage. However, this protective layer … Read more
The Ozone Hole: A Legacy of Ozone Depleting Substances The ozone layer, a fragile shield in the Earth’s stratosphere, plays a vital role in protecting life from harmful ultraviolet (UV) radiation from the sun. However, this shield has been under attack for decades, primarily due to the release of human-made chemicals known as ozone depleting … Read more
The subtopics of greenhouse gases are: Carbon dioxide Methane Nitrous oxide Ozone Water vapor Fluorinated gases Carbon dioxide is the most important greenhouse gas because it is the most abundant. It is released into the atmosphere when fossil fuels are burned, such as coal, oil, and natural gas. Methane is the second most important greenhouse … Read more
The Greenhouse Effect: A Vital Balance Tipping Towards Crisis The Earth’s climate is a delicate dance, a complex interplay of energy flows, atmospheric composition, and natural cycles. At the heart of this dance lies the greenhouse effect, a natural phenomenon that keeps our planet habitable. However, human activities are disrupting this delicate balance, amplifying the … Read more
