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...

Earth Has Been Sending Particles From Atmosphere To Moon For Billions Of Years, Study Finds
The process, which existed for billions of years, would eventually turn lunar soil into a long-running archive of Earth's atmosphere.

Can Amazon Rainforest Survive Future? Scientists Test It With 'Time Machine'
Deep in Brazil's Amazon, scientists have built a "time machine" pumping carbon dioxide into the rainforest canopy to simulate atmospheric conditions predicted for the future to gauge how the biome adapts, an open question to be discussed at the COP30

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.

Carbon Dioxide In Atmosphere Up By Record Amount In 2024
The increase in the amount of carbon dioxide in the atmosphere last year was the highest ever recorded, the United Nations said, calling for urgent action to slash emissions.

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).

Earth Will Lose Its Oxygen: Scientists Warn Of A Rapid Countdown
The findings also suggest oxygen may not be a permanent biosignature on habitable planets, impacting the search for extraterrestrial life.

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.

Curiosity Rover Observes Iridescent Clouds on Mars, Offering New Insights
NASA’s Curiosity rover has captured rare iridescent clouds drifting across the Martian sky, observed at high altitudes in twilight conditions. These carbon dioxide ice clouds were seen forming between 60 and 80 kilometres above the surface before evaporating as they descended. Scientists believe their presence hints at unknown cooling mechanisms ...
