The Indian monsoon has shifted over the past quarter century. Northwest India now receives substantially more rain than it once did, while a lack of rain sends the Indo-Gangetic Plain toward drought.…
A new study in Nature Communications discovers a gloomy climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate climate…
Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves. Many rivers flow into the Arctic Ocean including the Lena in Siberia and the Mackenzie River in Canada. The…
Human activity threatens climate and becoming more imminent than ever before. Among many contributing factors cities remain responsible for over 70% of global CO2 emissions largely due to industrial activities and transportation…
A scientific team has now directly documented and extensively sampled a buried system of “freshened” water beneath the seabed off New England, giving researchers their clearest evidence yet that these offshore aquifers…
Letters to US Federal Communications Commission raise concerns over tech firms’ plans to use reflective satellites and expand numbers in low Earth orbit. Proposals to deploy reflective mirrors and up to 1m…
Deep beneath our feet, a slow trickle of gold is escaping from the heart of Earth. That is the striking conclusion of a new study that used ultra-precise chemical fingerprints in Hawaiian…
Record low levels of Antarctic sea ice is having grim consequences for penguins yet to grow waterproof feathers. The mass drowning of emperor penguin chicks as sea ice is melted by the…
A new study suggests the Moon has been catching tiny pieces of Earth’s air for much of its history, quietly storing a chemical record of our planet’s atmosphere in its dusty soil.…
Officials say the plan targets river-lined gaps where border fencing is difficult or impossible to place. India is considering an unconventional proposal for border enforcement that includes deploying crocodiles and venomous snakes…
