Deep-sea mining poses significant risks for a vital, hidden part of the ocean. That’s the message from a new University of Hawaiʻi at Mānoa study, the first to truly look at the impact of mining waste.

A new study shows that lithium — a critical element used in rechargeable batteries and susceptible to supply chain disruption — can be recovered from battery waste using an electrochemically driven recovery process.

The waters bordering North America could soon be inhospitable to critical marine creatures if the Northeastern Pacific Ocean continues to acidify at the current rate, a new study shows.

The climate plans that countries have submitted to the U.N. will do too little to protect the world’s forests and their vast stores of carbon, experts say. Instead, plans lean heavily on “unrealistic” tree-planting schemes.

With global power demand from data centers expected to more than double by 2030, the MIT Energy Initiative (MITEI) in September launched an effort that brings together MIT researchers and industry experts to explore innovative solutions for powering the data-driven future.

Aviation currently contributes about 2.5% of total global carbon emissions, and with air travel demand expected to double by 2040, cutting those emissions has become a pressing priority.

Studying historical hourly weather data – and the amount of time that temperatures remain above or below certain thresholds – reveals several impacts of U.S. regional climate change trends.

As climate change increases the frequency of droughts, UCLA and UC Davis researchers found one overlooked side effect: People report more conflicts with wildlife during drought, when resources are scarce.

Earth scientists have discovered how continents are slowly peeled from beneath, fuelling volcanic activity in an unexpected place: the oceans.

The EU is considering introducing a blanket ban on the man-made chemicals called PFAS because of the risks they pose.
