Arctic sea ice melt slowdown since 2012 linked to atmospheric pattern shift

Phys.org: Earth science - Tue, 12/23/2025 - 16:10
A research team led by The Hong Kong University of Science and Technology (HKUST) scholars has discovered a significant slowdown in Arctic sea ice melting since 2012, with a decrease rate of 11.3% per decade to an insignificant downward trend of only −0.4% per decade.

Earth's growing heat imbalance driven more by clouds than air pollution, study finds

Phys.org: Earth science - Tue, 12/23/2025 - 15:03
Earth is taking in more energy than it releases back to space—a growing "energy imbalance" that is fueling global warming. A new study led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science finds that recent changes in air pollution are not the main reason this imbalance has increased.

Ultra-high-resolution lidar reveals hidden cloud structures

Phys.org: Earth science - Tue, 12/23/2025 - 14:50
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have developed a new type of lidar—a laser-based remote-sensing instrument—that can observe cloud structures at the scale of a single centimeter. The scientists used this high-resolution lidar to directly observe fine cloud structures in the uppermost portion of laboratory-generated clouds. This capability for studying cloud tops with resolution that is 100 to 1,000 times higher than traditional atmospheric science lidars enables pairing with measurements in well-controlled chamber experiments in a way that has not been possible before.

Mysterious, thermally insulating patches at the base of Earth's mantle

Phys.org: Earth science - Tue, 12/23/2025 - 14:39
With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 kilometers beneath our feet, there is a thin layer about 300 kilometers thick with remarkable structural complexity and compositional heterogeneity. Among these features are small-scale structures known as ultralow velocity zones (ULVZs) that have attracted intense scientific interest.

Southeast Asia's greenhouse gas emissions demand urgent regional action

Phys.org: Earth science - Tue, 12/23/2025 - 14:20
A new regional assessment shows that Southeast Asia is a major net source of greenhouse gases, with land-use change and rising fossil fuel use overwhelming natural carbon sinks, reservoirs that store carbon-containing chemical compounds for a long period.
