Rising sea levels could weaken coral reefs’ protective influence on Brazil’s coast

Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

Study: Major return on investment from improving climate observations

A well-designed climate observing system could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits by providing decision makers information they need to protect public health and the economy in the coming decades, according to a new study published today.

Scientists may have solved mystery of rapidly rising Indian Ocean sea level

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

New approach to geoengineering simulations is significant step forward

Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven cooling of the globe.

Polluted groundwater eroding Hawaiian coral reefs, study shows

Local land-based pollution makes coral reefs more vulnerable to ocean acidification and could trigger coastal coral reef ecosystem collapses sooner than projected, according to new research.

Scientists use seismic waves to measure tornado intensity

Seismic waves generated by tornadoes when they touch down could be used to measure a twister’s intensity, according to a new study that examined the May 2011 Joplin tornado. The findings could open the door to devising more accurate methods to study tornadoes from the ground.

Waves in lakes make waves in the Earth

Scientists at the University of Utah report that small seismic signals emanating from lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.

The missing mass — what is causing a geoid low in the Indian Ocean?

In a recent study, scientists explored the reasons behind the existence of the Indian Ocean Geoid Low, a point of low gravity found just south of the Indian peninsula.

Secrets of hidden ice canyons revealed

In a new study, scientists have discovered huge canyons cutting through the underbelly of Antarctica’s ice shelves, meaning they may be more fragile than previously thought. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.

Old Faithful’s geological heart revealed

Old Faithful is Yellowstone National Park’s most famous landmark. Millions of visitors come to the park every year to see the geyser erupt every 44-125 minutes. But despite Old Faithful’s fame, relatively little was known about the geologic anatomy of the structure and the fluid pathways that fuel the geyser below the surface. Until now.
