Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms      (via sciencedaily.com) 

The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero.

The world's atmospheric rivers now have an intensity ranking like hurricanes      (via sciencedaily.com) 

Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.

Underused satellite, radar data may improve thunderstorm forecasts      (via sciencedaily.com) 

Tens of thousands of thunderstorms may rumble around the world each day, but accurately predicting the time and location where they will form remains a grand challenge of computer weather modeling. A new technique combining underused satellite and radar data in weather models may improve these predictions, according to a team of scientists.

Seabirds in the eye of the storm      (via sciencedaily.com) 

Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.

How to predict city traffic      (via sciencedaily.com) 

A new machine learning model can predict traffic activity in different zones of cities. To do so, a researcher used data from a main car-sharing company in Italy as a proxy for overall city traffic. Understanding how different urban zones interact can help avoid traffic jams, for example, and enable targeted responses of policy makers -- such as local expansion of public transportation.

One is bad enough: climate change raises the threat of back-to-back hurricanes      (via sciencedaily.com) 

Driven by a combination of rising sea levels and climate change, destructive hurricanes and tropical storms could become far more likely to hit coastal areas in quick succession, researchers found. In some areas such double hits could occur as frequently as once every 3 years.

Human-wildlife conflicts rising worldwide with climate change      (via sciencedaily.com) 

Scientists reveal that a warming world is increasing human-wildlife conflicts globally. They show that climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.

Clues about the Northeast's past and future climate from plant fossils      (via sciencedaily.com) 

A team of researchers is working to understand the details of the climate for the eastern portion of the United States from the Miocene, which unfortunately is a blank spot on paleo-climate maps. New findings suggest the future climate will be very close to the warmer, wetter, and more homogeneous climate similar to conditions experienced 5 million years ago.

Why do Earth's hemispheres look equally bright when viewed from space?      (via sciencedaily.com) 

When seen from space, Earth's hemispheres -- northern and southern -- appear equally bright. For years, the brightness symmetry between hemispheres remained a mystery. In a new study, researchers reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.

Missouri is home to an array of natural resources, with forests among the state's most valuable ecosystems. As warmer temperatures fueled by climate change affect ecosystems globally, forests are under stress to adapt to these changes and ensure their survival in a warmer world. Researchers now introduce the 'ecosystem wilting point' concept, which explains how whole forests respond to drought.
