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.

Scientists Create Cleaner Polymers To Absorb CO2 and Improve Energy Tech
Researchers at Tohoku University have developed a new method for synthesising porous organic polymers (POPs) with high purity. By using iodine as an oxidant and removing residual impurities through ethanol washing, the polymers achieve superior porosity and CO2 adsorption efficiency. The study highlights their potential for gas separation, energy s...

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 ...

Ocean Warming Rate Quadruples Over Four Decades, Accelerating Climate Change
New research highlights a troubling acceleration in ocean warming, with the rate of temperature rise quadrupling since the 1980s. According to a study in Environmental Research Letters, ocean surface temperatures now rise at 0.27°C per decade, up from 0.06°C. This rapid warming, driven by greenhouse gases like CO2 and methane, is worsening Earth'...

New Dual-Reactor Tech Turns CO2 Into Protein for Food and Sustainability
A team of engineers in China has developed an innovative dual-reactor system that converts carbon dioxide into a high-protein product suitable for human and animal consumption. The two-stage process uses microbial electrosynthesis to turn CO2 into acetate, which is then used by bacteria to produce single-cell protein. This system promises a more su...

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...

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...

Global Fossil CO2 Emissions Hit Record High in 2024: Here's What You Need to Know
Global CO2 emissions from fossil fuels reached a record high in 2024 at 37.4 billion tonnes, up 0.8% from 2023, according to the Global Carbon Project. Despite progress in renewables and climate efforts, fossil fuel use has not yet peaked, raising concerns about reaching global warming limits. With 41.6 billion tonnes of CO2 projected overall, scie...

Ancient Log Discovery in Canada Shows How Wood Burial Could Be Key to Affordable Carbon Storage
A 3,775-year-old log, found by climate scientist Ning Zeng's team in Canada, has shown the potential of buried wood for long-term carbon storage. When covered by clay, the log retained most of its carbon, hinting at a cost-effective, natural solution for lowering atmospheric CO2 levels. Researchers suggest this low-cost strategy could lock away car...
