Robot that uses AI to pull weeds may reduce poisonous herbicide use by 70% for some crops.
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.
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…
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.
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.
Methane levels are currently sky-high, just like they were during Earth’s previous termination events.
Call for EU to match WHO’s air pollution regulatory limits as impact of climate emergency interlinks with human health
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.
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.
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.”
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.
