A new study warns that climate change will significantly reshape wind energy potential across the Middle East. While surface winds may intensify in some regions, wind speeds at turbine height are projected to decline—posing challenges for energy planners across the region. Using high-resolution climate modeling, the research highlights the urgent need to factor future wind dynamics into sustainable energy strategies.
Plankton may be tiny, but they play an important role in the ocean. As the foundation of marine ecosystems, they support ocean food webs and help regulate Earth’s climate by storing carbon. While lab studies have shown plankton can adjust their chemistry in response to environmental changes, a new global study reveals how these adaptations occur in the real ocean. The study will be published on May 23, 2025, in the journal Science Advances.
As sea levels climb and weather grows more extreme, coastal regions everywhere are facing a creeping threat: salt.
Salinization of freshwater and soils adversely affects 500 million people around the world, especially in low-lying river deltas.
A new study led by researchers at the University of Portsmouth, in partnership with Dhaka University and Curtin University, sheds light on how rising oceans are pushing saltwater into freshwater rivers and underground water sources in the world’s largest river mouth - the Bengal Delta in Bangladesh.
Temperatures around the world continue to rise – and the North Sea is no exception. Yet, in addition to this gradual warming, increasingly frequent and intense heat events also have consequences for marine organisms. Researchers at the Marine Station Helgoland, a research facility of the Alfred Wegener Institute, have quantified the frequency and intensity of these heatwaves along with their repercussions for plankton. They have also conducted an experiment that exposed the North Sea plankton community to different future warmer scenarios, both with and without heatwaves. The researchers found that gradual warming causes significant shifts in the species spectrum. When heatwaves are added, however, these alterations are amplified. The results have been published in three publications, most recently in Limnology and Oceanography.
Tropical cyclones increased infant mortality by an average of 11% across seven low- and middle-income countries between 2002 and 2021. The risk of death was highest during the first year of life after a damaging tropical cyclone — even if it is below hurricane strength. Storm impacts on prenatal care and child growth, an indicator of early-life nutrition, did not account for the rise in infant deaths. The findings underscore the need for improved disaster response and child health protections in cyclone-prone low- and middle-income regions.
As kelp forests decline in the warming coastal waters of the Gulf of Maine, turf algae – dense mats of red algae replacing kelp in many regions – may chemically interfere with kelp recovery, a new study reports. This complicates efforts to restore these crucial marine ecosystems. Kelp forests are ecologically and economically vital marine ecosystems that support diverse life forms and functions. However, despite their widely recognized importance, kelp forests worldwide are threatened with collapse due to climate change and/or overfishing. In many regions where kelp forests have disappeared, they have been replaced by dense, low-lying mats of chemically rich, filamentous red seaweeds, also known as turf algae. This shift has been linked to declines in biodiversity and major disruptions in coastal ecosystem dynamics. Some research suggests that turf algae may actively hinder the recovery of kelp through allopathy – a common biological phenomenon by which one organism produces biochemicals that influence the growth, survival, development, and reproduction of other surrounding organisms. Understanding whether turf algae chemically inhibit kelp recovery is essential to managing and restoring these rapidly changing marine environments.
Shane Farrell and colleagues investigated whether allopathic turf algae suppress the recovery of kelp forests in the warming waters of the Gulf of Maine. Farrell et al. discovered that while kelp forests have persisted in the cooler waters of northeastern Maine, those in the warmer southwest have collapsed and failed to recover, with turf algae now dominating these reefs. By comparing the chemical composition of water and seaweed samples from kelp- and turf-dominated reefs, the authors identified distinct chemical signatures produced by turf algae. Laboratory experiments show that these turf-derived compounds inhibit the early growth stages of kelp. The findings suggest that turf algae alter the chemical ecology of the environment in ways that actively prevent kelp from re-establishing. “Future resilience strategies for marine ecosystems should integrate chemical ecology into climate change models,” write Colette Feehan and Karen Filbee-Dexter in a related Perspective. “By illuminating these hidden processes, we can better develop a fuller picture of how climate change is reshaping ocean ecosystems – and how we might better protect them.”
