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”

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.

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
