Beef tops deforestation chart as palm oil and soy follow

New Nature Food analysis links two decades of forest loss to commodity farming, with beef the leading driver (about 120 million acres destroyed, mostly in the tropics like the Amazon) and beef-related emissions exceeding three times the US’s annual total. Oil palm and soy also cleared millions of tropical forests, while staples such as maize, rice, and cassava can have large footprints. The study suggests reducing beef can help rainforests, though global demand remains strong and data limitations complicate measurement of cocoa/coffee impacts.

Perseverance Finds Ancient Mars Warmer and Wetter Than Thought

New findings from NASA’s Perseverance in Jezero Crater suggest Mars during the Noachian epoch (about 4.1–3.7 billion years ago) was warmer and wetter than previously believed, with evidence of persistent rainfall indicated by kaolinite-rich clays and weathered rocks, challenging the cold, icy Mars theory and implying habitable conditions in the distant past.

Ancient Air Locked in 1.4-Billion-Year Salt Reveals Mesoproterozoic Atmosphere

Researchers analyzed gas inclusions in 1.4-billion-year-old halite from Ontario to directly measure Mesoproterozoic atmospheric oxygen (~3.7% of modern) and CO2 levels (~10× preindustrial), revealing a milder climate than previously thought and offering new insight into Earth's ancient atmosphere during the so-called 'Boring Billion.'

Climate Rule Repeal Sparks Legal Showdown

President Trump's administration moved to rescind the EPA's endangerment finding, a bedrock basis for regulating greenhouse gases under the Clean Air Act, triggering planned lawsuits by environmental groups and Democrat-led states that are likely to reach the Supreme Court as the Court shifts conservative, with years of litigation ahead that could reshape how U.S. climate policy is enforced and challenged.

Private wells across the U.S. tainted by PFAS “forever chemicals” go undetected

A sweeping AP investigation finds that PFAS, the so‑called forever chemicals, are quietly contaminating drinking water wells across the United States, including many private wells that homeowners may not test or even know are contaminated, raising health concerns and exposing gaps in monitoring and accountability that communities are pushing to close.

The Real Complete Protein May Be Found in Your Everyday Diet

A Washington Post Climate Coach column argues that the so‑called ‘most complete’ protein is likely one you already eat; with a balanced, varied diet you can meet daily protein needs without turning to exotic sources or meat-heavy regimens, and the popularity of protein trends (like protein water or snacks) tends to be more marketing than necessity.

Tectonic shifts steer Earth's climate more than previously thought

Tectonic shifts steer Earth's climate more than previously thought

New computer-based reconstructions of 540 million years show that the movement of Earth’s plates—especially mid-ocean ridges and continental rifts that drive carbon into and out of the oceans, and the subsequent subduction of carbon-rich sediments—have played a bigger role in driving greenhouse and icehouse climates than volcanic arcs alone. The deep-sea carbon cycle acts as a key regulator of atmospheric CO2, influencing past and future climate and informing climate models that consider tectonic processes alongside human emissions.

A Haunting Audio Recreates Earth's Near-Collapse of Its Magnetic Shield

Researchers converted ESA Swarm satellite data and geological records into sound to recreate the Laschamps geomagnetic reversal (~41,000 years ago), when Earth's magnetic field weakened to about 5% of its current strength, potentially increasing cosmic radiation and affecting climate and early human life; the eerie audio illustrates chaotic magnetic shifts and underscores current concerns about weakening regions like the South Atlantic Anomaly.

Trump's energy-cut pledge collapses as U.S. power bills rise

Trump's energy-cut pledge collapses as U.S. power bills rise

Guardian analysis of EIA data shows Trump failed to halve energy bills; 2025 electricity costs rose 6.7% year over year, adding about $116 per household, with DC up 23%, Indiana 17%, and Illinois 15%, while gas prices rose 5.2% and disconnections increased; experts say demand growth outpaced aging infrastructure and a policy mix that limits renewables, undermining the pledge.
