End of humanity? Blow‑by‑blow account of what would happen if the Yellowstone supervolcano erupted now‎

Around 631,000 years ago—a geological blink of an eye—catastrophe unfolded in what is now northwestern Wyoming, U.S. During what is thought to have been a series of immense volcanic eruptions, life within hundreds of kilometers of the blasts was shattered. Ash was dispersed across much of North America, and the effects were felt worldwide. This was a super-eruption of the massive volcanic system located in what is now Yellowstone National Park.

Environmental science takes an average of seven years to influence international policy, study finds‎

A new study led by the University of Alicante (UA) and the Mediterranean Center for Environmental Studies (CEAM) analyzes the barriers separating scientific knowledge from environmental policy and its effective implementation. The research sets out how long it takes for scientific knowledge in ecology to reach environmental policies and the extent to which these policies subsequently translate into real-world outcomes.
