The cycling between warm El Niño and cold La Niña conditions in the eastern Pacific (commonly referred to as the El Niño-Southern Oscillation, ENSO) has persisted without major interruptions for at least the last 11,000 years.

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere.

New research shows changes in tides and hurricane activity played a part in upending the Maya civilization centuries ago.

Human actions – mostly burning of biomass and fossil fuels – have dramatically altered the global nitrogen cycle, affecting natural habitats and contributing to acid rain.

Dams poorly mimic the temperature patterns California streams require to support the state’s native salmon and trout — more than three-quarters of which risk extinction. 

A new AI (artificial intelligence) tool is set to enable scientists to more accurately forecast Arctic sea ice conditions months into the future. 

A Texas A&M team has developed a concept that could decrease the cost and time it takes to install offshore wind turbines.

Scientists studying tropical forests in Africa’s mountains were surprised to uncover how much carbon they store, and how fast some of these forests are being cleared.

Urbanization is one of the most drastic forms of land-use change, and its negative consequences on biodiversity have been studied extensively in temperate countries such as Germany.
