Rainfall–salinity link sustains prolonged La Niña events, study reveals

Phys.org

La Niña—a climate phenomenon characterized by unusually cool sea surface temperatures in the central and eastern tropical Pacific Ocean—can persist for multiple years, exerting significant climate impacts worldwide. In recent decades, such prolonged La Niña […]

U.S. forests have stored more carbon in the past two decades than at any time in the last century, an increase attributable to a mix of natural factors and human activity, finds a new study.This […]

Grains of sand prove people—not glaciers—transported Stonehenge rocks

Phys.org

Ask people how Stonehenge was built and you’ll hear stories of sledges, ropes, boats and sheer human determination to haul stones from across Britain to Salisbury Plain, in south-west England. Others might mention giants, wizards, […]

Critical Atlantic Ocean currents kept going during last ice age, microfossils suggest

Phys.org

During the last ice age, the Atlantic Ocean’s powerful current system remained active and continued to transport warm, salty water from the tropics to the North Atlantic despite extensive ice cover across much of the […]

Dredging sand and silt has consequences for the North Sea

Phys.org

Through sand extraction and the disposal of dredged harbor silt, about 200 million tons of sediment are relocated every year in the coastal waters of the North Sea. The Wadden Sea is particularly strongly affected. […]

The way Earth’s surface moves has a bigger impact on shifting the climate than we knew

Phys.org

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing “icehouse” periods and warm “greenhouse” states.This post was originally published on this site

Self-esteem may predict who pursues leadership roles

A recent study has shown that self-esteem plays an important part in determining whether someone wishes to pursue a leadership role. The findings have implications for both organizational success and career development, underscoring, as they [...]
