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.

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.

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.

Weird green sand could sequester greenhouse gases and help combat climate change, say scientists

When waves crash over volcanic rocks, they set off tiny chemical reactions which pulls little bit of carbon dioxide out of the air and form hydrocarbonate.

Countries need to work together to remove carbon dioxide from the atmosphere in order to avoid climate change

A system needs to be devised where quotas are fairly allocated and countries that cannot fulfil their obligations allowed to trade with those who can remove CO2.
