Experts revive ancient techniques to make concrete more sustainable

A team of experts from EPFL, ETH Zurich, and Archiplein has developed a new type of non-reinforced concrete from stone offcuts. Using methods found in historical archives, the team reduced their use of carbon-intensive cement. They built and tested six load-bearing walls using recovered stone-quarry waste and three types of mortar-based binders.

An Unlikely Source of Greenhouse-Gas Emissions

Wildfires are making the Alaskan tundra leak methane. Chunks of carbon-rich frozen soil, or permafrost, undergird much of the Arctic tundra. This perpetually frozen layer sequesters carbon from the atmosphere, sometimes storing it for tens of thousands of years beneath…

They went hunting for fossil fuels. What they found could help save the world

White hydrogen – also referred to as “natural,” “gold” or “geologic” hydrogen – is naturally produced or present in the Earth’s crust and has become something of a climate holy grail.

‘Electrowinning’ could help win the race to clean up dirty steel

Startup Electra wants to replace blast furnaces with battery-like systems that use acid solution and clean electricity to pull pure iron out of low-grade steel ores.

Surging Methane Suggests Earth Is Brewing An Ice Age Termination Event

Methane levels are currently sky-high, just like they were during Earth’s previous termination events.

Climate crisis poses greatest risk to people with respiratory illnesses, experts warn

Call for EU to match WHO’s air pollution regulatory limits as impact of climate emergency interlinks with human health

Wealthiest 10% of US Households Responsible for 40% of Greenhouse Gas Emissions: Study

The richest tenth of U.S. households are responsible for 40% of all the nation’s greenhouse gas emissions, a study published Thursday revealed, underscoring what progressives say is the need for regulations and taxes on carbon-intensive investments.

Radical ways to fix the Earth: are they magic bullets or just band-aids?

Technologies like geoengineering may tackle global warming – but first we need to ditch fossil fuels for renewable energy

Red alga added to cow poop slashes methane emissions by almost half

A particularly impressive red alga has already shown great promise in dramatically reducing the alarming levels of methane gas produced by a cow’s enteric digestive system. Now, a team of scientists has moved from the animal’s belches to its tail end, in an effort to get to the bottom of the methane produced in the poop.

Study Shows Methane Leaks Put Climate Risk From Gas ‘On Par With Coal’

If fracked gas leaks, even a little, “it’s as bad as coal,” said the lead author. “It can’t be considered a good bridge, or substitute.”

‘Gateway to Hell’: Turkmenistan urged to plug gas leaks driving climate change

Home to the Darvaza Crater, a massive molten pit that has spewed flames and noxious gases for decades, Turkmenistan has the world’s worst record when it comes to climate-heating methane leaks.
