The unprecedented cost of the 2018 Kiīlauea eruption in Hawaiʻi reflects the intersection of distinct physical and social phenomena: infrequent, highly destructive eruptions and atypically high population growth, according to a new study published in Nature Communications and led by University of Hawaiʻi at Mānoa researchers
Coral reefs are facing threats that are driving their decline, including the planet’s warming waters.
In the early solar system, rocky planets, such as Earth, Mercury, Venus and Mars, and the Moon may have been “lava worlds,” with oceans of magma blanketing the surface, according to planetary scientists.
Large parts of the Sahara Desert were green thousands of years ago, evidenced by prehistoric engravings in the desert of giraffes, crocodiles and a stone-age cave painting of humans swimming.
To survive the open ocean, tiny fish larvae must find food, avoid predators and navigate ocean currents to their adult habitats.
A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.
Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles.
Maps of the American West have featured ever darker shades of red over the past two decades. The colors illustrate the unprecedented drought blighting the region.
Rising temperatures, increased CO2 will drive trees, grasses, weeds to produce more pollen
A new coral reef conservation tool has been developed by University of Hawaiʻi at Mānoa researchers using cutting-edge artificial intelligence (AI) technology
A 2022 study led by Dartmouth professor Mathieu Morlighem, reveals that the Northeast Greenland Ice Stream (NEGIS) is losing ice at an alarming rate, which could lead to up to six times more sea-level rise by 2100 than previously projected.
As part of global ocean circulation, warm water in the upper layer flows from the Pacific Ocean to the Indian Ocean through the Indonesian Archipelago.
Over the past 200 years, the ocean and atmosphere have been accumulating massive amounts of carbon dioxide as factories, automobiles, airplanes and more churn out the powerful greenhouse gas.
Pollution from on-site sewage disposal systems and injection wells is impacting coral reefs worldwide. Through onsite testing and reef surveys at Puakō, Hawaiʻi Island, researchers from the University of Hawaiʻi at Hilo, UH Mānoa and other organizations found sewage pollution was moderate on the offshore reef from seeps, and that water motion mixed and diluted the pollutant.
The war in Ukraine and the international isolation of Russia has harmed biodiversity conservation according to a new study, published in Frontiers in Conservation Science.
During August 2019, more than 40,000 tourists visited Hawaiʻi’s Molokini island—off of Maui’s southwestern coast—to snorkel or dive
Irreversible loss of the West Antarctic and Greenland ice sheets, and a corresponding rapid acceleration of sea-level rise, may be imminent if global temperature change cannot be stabilized below 1.8°C, compared to preindustrial levels.
A novel virus, potentially fatal to whales and dolphins, has been discovered by researchers at the University of Hawaiʻi Health and Stranding Lab.
Clear evidence that marine phytoplankton are much more resilient to future climate change than previously thought is the focus of a study published in Science Advances by an international team of scientists, including University of Hawaiʻi at Mānoa oceanography professor David Karl.
Under a project led by the RIKEN Center for Computational Science, researchers have used computer simulations to show that weather phenomena such as sudden downpours could potentially be modified by making small adjustments to certain variables in the weather system.
