  • These simple changes can make AI research much more energy efficient

    The Large Hadron Collider has helped scientists to discover three never-before-seen particles

    Since the first paper studying this technology’s impact on the environment was published three years ago, a movement has grown among researchers to self-report the energy consumed and emissions generated from their work. Having accurate numbers is an important step toward making changes, but actually gathering those numbers can be a challenge. “You can’t improve […]

    35 innovators under 35: Climate change

    Clean energy technologies in the electric power, transportation, industry, and building sectors will drive this change, because the use of fossil fuels in these areas causes three-quarters of global greenhouse-gas emissions. We’ll also need technologies to slash emissions from agriculture and deforestation and to remove carbon dioxide from the atmosphere and store it. Most of […]

    How Charm Industrial hopes to use crops to cut steel emissions

    The iron and steel industry produces about 4 billion tons of carbon emissions each year, accounting for around 10% of all energy-related climate pollution, according to a 2020 report by the International Energy Agency. Those figures have risen sharply this century, driven by rapid economic growth in China and elsewhere. The hefty emissions and increasingly […]

  • UN climate report: Carbon removal is now “essential”

    UN climate report: Carbon removal is now “essential”

    Cutting emissions that rapidly would require breakneck transitions to new technologies as well as steep reductions in energy demand. That would take unprecedented human behavior changes and efficiency improvements, all of which would be “quite challenging to accomplish in the real world,” says Zeke Hausfather, a contributor to an earlier working group for the latest […]

  • Pulling methane out of the atmosphere could slow global warming—if we can figure out how to do it

    Pulling methane out of the atmosphere could slow global warming—if we can figure out how to do it

    “There’s probably nothing we could do that has a bigger effect on shaving peak temperatures over the next few decades than removing methane,” says Rob Jackson, a researcher at Stanford and a coauthor of both studies. Methane is relatively scarce: carbon dioxide is about 200 times more concentrated in the atmosphere. Nevertheless, it has contributed […]
