The reactive and piecemeal approach historically used to manage beaches in Hawai'i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O'ahu, Hawai'i could be lost before mid-century, according to a new study by researchers in the Coastal Geology Group at the University of Hawai'i at Mānoa.
Analysis published in Scientific Reports is based on climate models for the mid-Pliocene period, which occurred 3 million years ago and shared characteristics with present-day warming.
Two new studies from the Woods Hole Oceanographic Institution (WHOI) investigate marine heatwaves and currents at the edge of the continental shelf, which impact regional ocean circulation and marine life.
Sound generated by seismic events on the seabed can be used to determine the temperature of Earth's warming oceans.
New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions. By using a high-speed stereophotogrammetry system, investigators were able to focus on how the shell shape, body geometry, and body size affect their swimming behavior from a fluid mechanics perspective, while image analysis and metabarcoding related swimming behaviors to night time and daytime vertical distributions.
Over 99% of terrestrial ice is bound up in the ice sheets covering Antarctic and Greenland. Even partial melting of this ice due to climate change will significantly contribute to sea level rise. But how much exactly? For the first time ever, glaciologists, oceanographers, and climatologists from 13 countries have teamed up to make new projections.
For the first time, it is possible to accurately predict severe drought up to 18 months in advance in Tropical South America. Early warnings of upcoming droughts are imperative for mitigating the impact on millions of people depending on the Amazon rainforest ecosystem. Additionally, droughts threaten the delicate ecosystems of the rainforest in South America.
Deep-sea coral reefs face challenges as changes to ocean chemistry triggered by climate change may cause their foundations to become brittle, a study suggests.
An international consortium of researchers under the aegis of CMIP6 has calculated new estimates for the melting of Earth's ice sheets due to greenhouse gas emissions and its impact on sea levels, showing that the ice sheets could together contribute more than 40 cm by the end of 2100.
A new study finds a trigger for the Little Ice Age that cooled Europe from the 1300s through mid-1800s, and supports surprising model results suggesting that under the right conditions sudden climate changes can occur spontaneously, without external forcing.
