A new route to faster PPP-AR

Aerospace Information Research Institute, Chinese Academy of Sciences
Peer-Reviewed Publication

Fast, precise Global Navigation Satellite System (GNSS) positioning depends on how well models describe the ionosphere, the electrically charged region that bends and delays satellite signals.

Traveling tropical disturbance increases rainfall across the Hawaiian Islands

University of Hawaii at Manoa
Peer-Reviewed Publication

A new study revealed that the Madden–Julian Oscillation (MJO), a large-scale tropical disturbance that travels eastward through the tropics every 30–60 days, significantly influences climate conditions in Hawaiʻi. Their research showed that during active MJO phases, rainfall increases across the islands, especially on windward slopes. In contrast, suppressed MJO phases tend to produce drier conditions.

New Hampshire ski industry concerned about climate change

University of New Hampshire
Reports and Proceedings

New research out of the University of New Hampshire reveals that the majority of New Hampshire ski industry professionals are concerned about the effects of global warming on the ski industry, which generates close to $278.8 million each season in the Granite State, and believe more should be done. The study released by UNH’s Carsey School of Public Policy shows that this shared unease suggests a readiness to adopt sustainable practices and advocate for industry-wide adaptations.

New study shows linens, not equipment emissions, dominate ultrasound’s carbon footprint

American College of Radiology
Peer-Reviewed Publication

A new research study published in the Journal of the American College of Radiology found that unlike other modalities, linens and disposable supplies account for most of ultrasound’s annual emissions – not equipment energy use.

Much of humanity may face hot-dry extremes five times more often by end-century

American Geophysical Union
Peer-Reviewed Publication

In their current state, climate policies around the world could leave a significant chunk of the global population exposed to simultaneous extreme heat and drought over five times more often by the end of this century than during the mid-to-late 20th century, according to a study published in Geophysical Research Letters.

Swapping meat and dairy for plant-based foods cuts climate pollution by 35%, randomized clinical trial shows

Physicians Committee for Responsible Medicine
Peer-Reviewed Publication

A simple change on the dinner plate could deliver a powerful climate impact. New research published in BMJ Nutrition, Prevention & Health shows that replacing meat and dairy with a low‑fat vegan diet that includes soybeans reduced diet‑related greenhouse gas emissions by 35%. For the average individual, that reduction is comparable to eliminating roughly 600 miles of driving each year.

Institute of Industrial Science, The University of Tokyo and George Mason University scientists mine past air temperature forecasts, lower cost with greater subseasonal prediction accuracy

Institute of Industrial Science, The University of Tokyo
Peer-Reviewed Publication

Researchers at Institute of Industrial Science, The University of Tokyo and George Mason University‘s College of Science have developed a new method that improves air temperature forecasts one to five weeks in advance—without requiring additional model simulations.

Wildfires accelerate winter snowmelt in Oregon's western Cascades, PSU study finds

Portland State University
Peer-Reviewed Publication

The Pacific Northwest has seen below-normal snow this season — and new research from Portland State University suggests that the region's snowmelt-dependent water resources could face growing challenges in the years ahead as forest fires and winter rainstorms become more frequent.

Climate change may produce “fast-food” phytoplankton

Massachusetts Institute of Technology
Peer-Reviewed Publication

MIT scientists found that as sea surface temperatures rise over the next century, phytoplankton in polar regions will adapt to be less rich in proteins, heavier in carbohydrates, and lower in nutrients overall.
