Scientists drilling deep into ancient rocks in the Arizona desert say they have documented a gradual shift in Earth’s orbit that repeats regularly every 405,000 years, playing a role in natural climate swings. Astrophysicists have long hypothesized that the cycle exists based on calculations of celestial mechanics, but the authors of the new research have found the first verifiable physical evidence. They showed that the cycle has been stable for hundreds of millions of years, from before the rise of dinosaurs, and is still active today. The research may have implications not only for climate studies, but our understanding of the evolution of life on Earth, and the evolution of the Solar System. It appears this week in the Proceedings of the National Academy of Sciences.

As coastal lands in Louisiana erode, researchers, environmentalists and engineers are all searching for ways to preserve the marsh coastline.

Researchers at Indiana University have developed a new method for identifying communities that may be negatively affected by clean energy policies designed to hasten the move from fossil fuels to more environmentally friendly solutions.

New research from the University of North Carolina at Chapel Hill and collaborators found that most marine life in marine protected areas will not be able to tolerate warming ocean temperatures caused by greenhouse gas emissions. Marine protected areas have been established as a haven to protect threatened marine life, like polar bears, penguins and coral reefs, from the effects of fishing and other activities like mineral and oil extraction. The study found that with continued “business-as-usual” emissions, the protections currently in place won’t matter, because by 2100, warming and reduced oxygen concentration will make marine protected areas uninhabitable by most species currently residing in those areas.

Kilauea — Hawaii's most active volcano — began spewing lava into a residential area on Thursday, prompting evacuations after hundreds of small earthquakes in recent days telegraphed an impending eruption.

Strong vertical wind shear had taken its toll on Tropical Cyclone Flamboyan when NASA's Aqua satellite passed over the Southern Indian Ocean. Flamboyan, now a subtropical cyclone, had been stretched out and its only precipitation pushed southeast of the center.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible image of Flamboyan on May 2 at 3:50 a.m. EDT (0750 UTC). The storm was devoid of rainfall with the exception of the southeastern quadrant. Wind shear has pushed all the storm southeast of the center.

The intensity and frequency of strong tropical cyclones, as well as cyclone landfalls, have increased in recent decades in the northwestern Pacific Ocean, raising speculation about the root cause of the surge in destructive Category 4 and 5 storms.

Now atmospheric researchers at the University of Hawaiʻi at Mānoa‘s International Pacific Research Center (IPRC) have published a study in Scientific Reports showing a strong connection between sea surface temperature patterns associated with the Global Warming Hiatus phenomenon and changes in cyclone activity over the northwest Pacific Ocean, particularly increasing intensities in coastal regions of East Asia.

Following an extensive ground and aerial survey led by wind engineering experts at Western, it has been determined that the tornado outbreak of June 18, 2017 in southern Québec is officially the largest recorded in the province’s history and, consequently, one of the largest ever recorded in Canada.

Thanks to mom and dad, baby reef fish may have what it takes to adjust to hotter oceans.

In a rapidly changing climate, the decline of animal populations is a very real concern. Today, an international team of researchers report new evidence of reef fish adjusting to global warming conditions at the genetic level.

Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades.
