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).

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 ...

NASA’s Curiosity Rover Captures Stunning Feather-Shaped Iridescent Cloud on Mars
A remarkable feather-shaped iridescent cloud was spotted by NASA’s Curiosity rover on Mars. Captured during a seasonal imaging campaign, this phenomenon provides valuable data on Martian weather patterns. Scientists believe such clouds help study particle sizes and atmospheric changes. The cloud, composed of either water ice or carbon dioxide ice...

Google Signs Deal To Buy Carbon Credits From Indian Farms
Google will buy carbon credits from an Indian initiative that turns large amounts of agricultural waste into biochar - a form of charcoal that removes carbon dioxide from the atmosphere and returns it to the soil, it said on Thursday.

Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere
Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

El Nino and Massive Volcanic Eruptions Triggered Mass Extinction of Life 250 Million Years Ago
The worst mass extinction in Earth's history, 250 million years ago, was triggered by extreme El Niño events and volcanic eruptions in Siberia. These eruptions released vast amounts of carbon dioxide into the atmosphere, causing severe climate changes. The warming environment led to the death of 90% of species on land and in the oceans. While this...

Antarctica Was Last Ice-Free 34 Million Years Ago: What Triggered This Climate Shift?
Antarctica, which is nearly four times the size of the United States, was not always covered in ice. The last time it was ice-free was 34 million years ago during the Eocene-Oligocene boundary. At that time, global temperatures were higher, and carbon dioxide levels in the atmosphere were much higher than today. However, a significant drop in CO2 l...

Forests Emit Carbon Dioxide for Years After Wildfires, Study Finds
A recent study has found that forests destroyed by wildfires continue to emit carbon dioxide (CO₂) for years after the flames die down. The research, conducted in Sweden’s boreal forests, revealed that burnt areas release CO₂ at a rate that more than doubles the amount emitted during the fire itself. These findings are particularly concerning...
