POSTECH (Pohang University of Science and Technology) Professor Hyung Joo Lee's research team, including integrated program students Min Young Shin and Na Rae Kim, has published the results of a study analyzing how the combined effects of droughts and wildfires influence fine particulate matter (PM2.5) in California, U.S., using 15 years of data.

Harnessing technology and global collaboration to understand peatlands

Phys.org: Earth science - Wed, 10/15/2025 - 16:03

Peatlands are among the world's most important yet underappreciated ecosystems. They are a type of wetland that covers a small fraction of Earth's land, while containing the most carbon-rich soils in the world.

Typhoon leaves flooded Alaska villages facing a storm recovery far tougher than most Americans will ever experience

Phys.org: Earth science - Wed, 10/15/2025 - 15:40

Remnants of a powerful typhoon swept into Western Alaska's Yukon-Kuskokwim Delta on Oct. 12, 2025, producing a storm surge that flooded villages as far as 60 miles up the river. The water pushed homes off their foundations and set some afloat with people inside, officials said. More than 50 people had to be rescued in Kipnuk and Kwigillingok, hundreds were displaced in the region, and at least one person died.

On 30 July, a magnitude 8.8 earthquake off Russia's Kamchatka Peninsula triggered a tsunami that spread across the Pacific Ocean.

Rising seas and sinking cities signal a coastal crisis in China

Phys.org: Earth science - Wed, 10/15/2025 - 15:00

A team of scientists led by Rutgers researchers has uncovered evidence that modern sea level rise is happening faster than at any time in the past 4,000 years, with China's coastal cities especially at risk.

Australia's rainforests are the first to switch from carbon sink to carbon source, study warns

Phys.org: Earth science - Wed, 10/15/2025 - 15:00

The trunks and branches of trees in Australia's tropical rainforests—also known as woody biomass—have become a net source of carbon dioxide to the atmosphere, according to a new international study.

Locking carbon in trees and soils could help 'stabilize climate for centuries'—if done correctly

Phys.org: Earth science - Wed, 10/15/2025 - 15:00

A team of researchers, led by Cambridge University, has now formulated a method to assess whether carbon removal portfolios can help limit global warming over centuries. The approach also distinguishes between buying credits to offset risk versus claiming net-negative emissions.

Study highlights the benefits of mangroves for reducing property damage during hurricanes

Phys.org: Earth science - Wed, 10/15/2025 - 14:30

A new study led by the UC Santa Cruz Center for Coastal Climate Resilience (CCCR) and East Carolina University (ECU) has found that mangroves significantly reduced storm surges and property damages during Hurricanes Irma in 2017 and Ian in 2022.

Earthquake damage at deeper depths occurs long after initial activity, study finds

Phys.org: Earth science - Wed, 10/15/2025 - 13:22

Earthquakes often bring to mind images of destruction, of the Earth breaking open and altering landscapes. But after an earthquake, the area around it undergoes a period of post-seismic deformation, where areas that didn't break experience new stress as a result of the sudden change in the surroundings. Once it has adjusted to this new stress, it reaches a state of recovery.

Boron isotopes reveal how nuclear waste glass slowly dissolves over time

Phys.org: Earth science - Wed, 10/15/2025 - 13:13

A new study has uncovered how tiny differences in boron atoms can help scientists better predict the long-term behavior of glass used to store hazardous waste. The findings, published in Environmental and Biogeochemical Processes, could improve forecasts of how radioactive materials are released from storage over thousands of years.

Methane from overlooked sources higher than predicted in Osaka, Japan

Phys.org: Earth science - Wed, 10/15/2025 - 13:05

Methane is a greenhouse gas that is more than 25 times as potent as CO2 in warming the Earth. Reducing methane emissions is necessary to reduce the impact of global warming.
