Sinking Calcium Carbonate Locked Away Greenhouse Gases, Reveals New Study
Scientists have solved a 66-million-year climate mystery, explaining how Earth cooled from a tropical greenhouse to an ice-capped world. New research reveals ocean calcium levels dropped by more than half, reshaping marine chemistry. As calcium declined, oceans locked away more carbon dioxide, lowering atmospheric CO2. The study links deep-Earth pr...

Traffic, Not Stubble Burning, Keep Delhi Air 'Severe': Report
For most of October and November, Delhi pollution levels hovered between 'very poor' and 'severe', fuelled by a rising "toxic cocktail" of PM2.5, nitrogen dioxide (NO2) and carbon monoxide (CO) emitted mainly from vehicles and other local sources.

Atmospheric Carbon Dioxide Soars to 424PPM, Marking Biggest Yearly Jump Ever
The WMO reports Earth’s atmospheric CO₂ reached 422.8 ppm in 2024 — the biggest annual rise ever recorded. Driven by fossil-fuel emissions, wildfires, and weakening carbon sinks, the surge intensifies global warming. Scientists warn that delayed emission cuts could entrench irreversible changes in weather, ecosystems, and sea levels.

Projections Of Future Global Warming Exaggerated: Trump-Vetted Scientists
A new report from the US Department of Energy says projections of future global warming are exaggerated, while benefits from higher levels of carbon dioxide such as more productive farms are overlooked.

Rock On: How Crushed Stone Could Help Fight Climate Change
From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland globally in a novel bid to combat climate change. The technique is called Enhanced Rock Weathering (ERW).

World May Exhaust 1.5 Degree Celsius Carbon Budget In 3 Years: Scientists
If the world continues to release carbon dioxide at the current rate, the carbon budget for limiting global warming to 1.5 degrees Celsius will be exhausted in just over three years, according to an international group of scientists.

Scientists Can Tell When A Volcano Is About To Erupt Using This 'Green' Cue
Scientists can tell when a volcano is about to erupt by looking at the vegetation around and its colour.

Study Finds Grey Seals Can Track Blood Oxygen to Prevent Drowning
A study has revealed that grey seals can monitor their blood oxygen levels to determine when they need to surface for air. Researchers tested seals in controlled environments, exposing them to different oxygen and carbon dioxide levels. The findings confirmed that higher oxygen led to longer dives, while reduced oxygen shortened them. Surprisingly,...

Atmospheric CO2 Levels Reach 8,00,000 Year-High In 2023: Report
The World Meteorological Organization's (WMO) State of the Climate report said the past 10 years (2015-2024) were the warmest on record, with each of the last eight years setting new highs for ocean heat content.

Solar System’s Journey Through Orion Complex May Have Altered Earth’s Climate
Scientists have studied the solar system’s passage through the Orion complex, a dense region in space, around 14 million years ago. According to researchers, this movement may have compressed the heliosphere and increased interstellar dust reaching Earth. This dust could have influenced the planet’s climate and left traces in geological records...
