New Global Marine Heat Wave Forecasts Predict Ecological and Economic Consequences

New Global Marine Heat Wave Forecasts Predict Ecological and Economic Consequences

Researchers have created worldwide forecasts that can give up to a year’s notice of marine heatwaves, which are rapid and substantial spikes in ocean temperatures that can have a significant impact on ocean ecosystems. The forecasts published in Nature may aid fishing fleets, ocean manageme.....

The Effects of Ancient Carbon Releases Indicate Future Climate Scenarios

The Effects of Ancient Carbon Releases Indicate Future Climate Scenarios

Around 56 million years ago, a large release of greenhouse gases, most likely generated by volcanic activity, resulted in a period of intense global warming known as the Paleocene-Eocene Thermal Maximum (PETM). A smaller episode of warming and ocean acidification triggered by a shorter burst of c.....

Based on Deep-Diving Tiny Organisms, Scientists can Predict Carbon Transfer in the Ocean

Based on Deep-Diving Tiny Organisms, Scientists can Predict Carbon Transfer in the Ocean

The bacteria that latch onto particles at the ocean’s surface, dubbed hitchhikers, have a large role. They float along until they reach the ocean’s deepest depths, transmitting carbon to the ocean’s deepest waters. Although measuring the rate has been difficult until recently, t.....

Oldest Human DNA from Africa sheds light on Ancient Population Change

Oldest Human DNA from Africa sheds light on Ancient Population Change

An examination of ancient and modern DNA reveals that ancient Africans looking for mates swapped long-distance travel for localized relationships some 20,000 years ago. Our new study, led by an interdisciplinary team of 44 experts from 12 nations, contributes to answering these issues. We almost .....

New Research Contradicts the Popular Belief that Salt Marshes Form from Marine Debris Washed Ashore During Storms

New Research Contradicts the Popular Belief that Salt Marshes Form from Marine Debris Washed Ashore During Storms

New research undertaken by the University of Massachusetts Amherst into the life and times of a salt marsh in New England substantially alters our understanding of how salt marshes obtain the silt that keeps them alive. This study, which was just published in the Journal of Geophysical Research: .....

60 Million People in European Cities are Exposed to Noise Levels that are Harmful to their Health as a result of Road Traffic

60 Million People in European Cities are Exposed to Noise Levels that are Harmful to their Health as a result of Road Traffic

The Barcelona Institute for Global Health (ISGlobal), a center financed by the “la Caixa” Foundation, conducted a study in 749 European towns to measure the levels of noise caused by vehicle traffic and its impact on health. Nearly 60 million adults are exposed to dangerous levels of .....

During the Time of Norse Occupation in Greenland, Rapid Glacial Advance Reconstructed

During the Time of Norse Occupation in Greenland, Rapid Glacial Advance Reconstructed

The Greenland Ice Sheet is the world’s second-largest ice sheet, and it has the potential to considerably contribute to global sea-level rise in a warming world. Understanding the Greenland Ice Sheet’s long-term record, which includes both glacial advance and retreat, is crucial for e.....

With Climate Change, the World’s Coldest Forests are Shifting Northward

With Climate Change, the World’s Coldest Forests are Shifting Northward

Rising temperatures are driving Earth’s coldest forests to relocate northward, according to new research from Northern Arizona University, raising concerns about biodiversity, increasing wildfire danger, and the growing implications of climate change on northern communities. The article, .....

Warming of the Indian Ocean may Reduce the Amount of Rain that Falls in South Asia

Warming of the Indian Ocean may Reduce the Amount of Rain that Falls in South Asia

The summer monsoon is known for its torrential rains. It usually occurs between the months of April and September. Warm, moist air from the southwest Indian Ocean drifts toward India, Sri Lanka, Bangladesh, and Myanmar as winter draws to a close. These places experience a humid environment and he.....

A New Kind of Ice has been Discovered

A New Kind of Ice has been Discovered

UNLV researchers have found a new type of ice that reshapes the properties of water at extreme pressures. Solid water, or ice, is similar to many other materials in that it may create various solid materials depending on temperature and pressure circumstances, such as carbon-creating diamonds or .....

Climate Change has Caused the Demise of Ancient Liangzhu Culture

Climate Change has Caused the Demise of Ancient Liangzhu Culture

A sophisticated society that built a city of canals known as “China’s Venice of the Stone Age” vanished 4,000 years ago. Historians have long debated whether the collapse of the Liangzhu culture was caused by war, disease, or famine. Climate change has now been identified as a m.....

Mineral Dating Provides New Insights into Critical Tectonic Processes

Mineral Dating Provides New Insights into Critical Tectonic Processes

The incorporation of nearly all geologic aspects of Earth’s outer rock shell (the lithosphere) into a unifying theory known as plate tectonics has had a significant impact on the scientific understanding of our dynamic planet. Continents move on huge slabs or plates of dense rock about 100 .....
