Why is a Japanese firm testing vending machines that suck carbon dioxide from atmosphere?
The soft drinks division of the Tokyo-Asahi group will begin testing machines – which absorb around 60 kilogrammes of carbon dioxide per year – next month as part of its carbon-neutral ambitions. Experts say removing CO2 from the atmosphere remains a monumental challenge
Explained: How scientists plan to use oceans to combat global warming
Scientists from University of California Los Angeles (UCLA) have been working for two years on SeaChange — an ambitious project that could one day boost the amount of CO2, a major greenhouse gas, that can be absorbed by our seas
Why a tax on cow burps might not be the best way to fight climate change
Although methane doesn’t last as long, it is many times more potent than carbon dioxide at warming the climate. That’s why it’s a target for policymakers. But is taxing cow burps a good climate solution?
How Kate Winslet managed to hold her breath for more than 7 minutes in 'Avatar 2'
Actor Kate Winslet now holds the record for a breath hold on a movie set — seven minutes and 15 seconds for ‘Avatar: The Way of Water’. The record could be accomplished by inhaling 100 per cent oxygen before and hyperventilating, which is breathing faster and deeper than normal
James Webb telescope finds carbon dioxide for first time in exoplanet atmosphere
Although the exoplanet would never be able to support life as we know it, the successful discovery of CO2 gives researchers hope that similar observations could be carried out on rocky objects more hospitable to life
Germany inaugurates first commercial synthetic kerosene plant; Lufthansa is first customer
Burning synthetic kerosene releases only as much CO2 into the atmosphere as was previously removed to produce the fuel, making it “carbon neutral”
World's largest carbon dioxide capturing plant starts in Iceland
The plant is designed to capture 4,000 tonnes of carbon dioxide out of the air every year
Value of nature: What is the cost of the trees in the Gabon forests that suck in carbon dioxide
"If a tree is standing it's worth nothing, if you cut it down it's worth something, but that's useless for the planet," said Carlos Manuel Rodriguez, head of the Global Environment Facility.
Nitrous oxide, potent greenhouse gas, are on the rise from ocean dead zones
The oceans currently account for around 25 percent of global N2O emissions, and scientists are working to improve estimates of marine contributions.
Amazon's hydropower plant contributes significantly to greenhouse gas emissions
Indigenous and environmental groups protested the construction in 1990s but it was revived as an ROR plant in 2011.
Perseverance rover converts CO2 into oxygen on Mars for the first time
MOXIE produced five grams of oxygen, equal to 10 minutes of breathable oxygen for astronaut carrying out normal activity.
Carbon might boost forest, grassland growth but absorption capacity of soil decreases
The new study adds to growing evidence that the terrestrial carbon sink is weaker than once thought.
Lenovo extends 'carbon offset' service to customers in India, Asia Pacific
Customers can choose from a range of projects overseen by the UN and ClimeCo, a voluntary carbon credits producer in the US.
CO2 levels in the atmosphere is 50 percent higher than 18th century
This is despite an unprecedented fall in greenhouse gas emissions in 2020 because of the pandemic.
Peatlands keep a lot of carbon out of Earth's atmosphere, but that could end with warming and development
Although they only occupy three percent of the global land area, peatlands contain about 25 percent of global soil carbon — twice as much as the world’s forests.
Despite lockdowns, pollution pledges, Earth will get more than three degrees warmer by end of 2100
With just over 1C of warming since pre-industrial times, Earth is already experiencing stronger and more frequent droughts, wildfires and superstorms rendered deadlier by rising seas.
Most habitable region for life would have been several miles below Martian surface: Scientists
Scientists examined Mars datasets to see if heating via geothermal heat would have been possible in that area and found that conditions needed for subsurface melting would have been present on ancient Mars
Trees that grow quickly die faster releasing CO2, challenges notion that forests are sinks for carbon emissions
A researcher said that this suggests that fossil-fuel-based emissions can be 'offset' by planting trees (or avoiding deforestation) really does not stand up to scientific scrutiny.
Climate won’t warm as much as we feared, but will cross the limits we've set, scientists say
Researchers explain why relaxed efforts against carbon emissions will not avoid substantial warming.
Bacteria that eats metal, processes carbon accidentally discovered on dirty lab equipment
Such microbes were predicted to exist over a century ago, but none had been found or described until now.
