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.

NASA Curiosity Rover Potentially Deciphers Mars’ Missing Carbonate Mystery
NASA’s Curiosity rover potentially ended the mystery of the ancient atmosphere and missing carbonates. The research uncovers the potential reasons behind the temperature of the planet Mars and how it has supported the liquid water on the planet. Explore the findings and the discoveries made by NASA’s Curiosity rover.

Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...

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.

New Farm Fertilizer Could Remove CO2 from Air, Improve Soil Quality
Researchers have identified a method to accelerate carbon mineralisation using calcium silicates in farm fertilizers. The process could sequester billions of tons of CO2 while benefiting soil health. Unlike traditional magnesium silicates, calcium silicates react faster with CO2, making the approach more efficient. Scientists are exploring ways to ...

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 ...

Mutant Cyanobacterium Chonkus Could Help Combat Climate Change with Carbon Storage
Chonkus, a mutant strain of cyanobacterium, has been found to store more carbon and sink faster than typical strains. Discovered by Max Schubert and his team at the Wyss Institute, this microbe could assist in carbon sequestration efforts. Chonkus' quick sinking ability and high carbon storage capacity suggest it may play a role in reducing atmosph...

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...

Newly Discovered Oxygen Reaction Existed in Primitive Atmosphere, Sheds Light on Origin of Life
Scientists have uncovered a new way oxygen could form in carbon dioxide-rich atmospheres without the involvement of life. The discovery, led by researchers from the University of Science and Technology of China, shows that a reaction between helium ions and CO2 can produce molecular oxygen. This process challenges traditional methods of life detect...

New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery
A new study on PDS 70b, a forming exoplanet located 400 light-years away, reveals a significant mismatch between its atmospheric composition and the surrounding protoplanetary disk. This discovery casts doubt on existing planet formation models, suggesting that more research is needed to understand how planets gather materials and elements during t...

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...

Plankton’s Ability To Sequester Carbon Is Influenced by Ocean Density, Study Shows
A study published in Royal Society Open Science explores how changes in ocean density influence marine plankton, particularly the foraminifera species Trilobatus trilobus, in incorporating carbon into their shells. These organisms play a key role in the carbon cycle by sequestering carbon in the ocean floor after death. The study, led by Dr Stergio...
