Ocean warming, primarily resulting from the escalating levels of greenhouse gases in atmosphere, leads to a rise temperature Earth's oceans. These act as heat-trapping agents, contributing overall phenomenon global warming. In order gain comprehensive understanding how ocean warming impacts marine ecosystems, thorough literature review was conducted over span three decades, involving 2484 initial publications. The systematic screening facilitated by utilizing Abstrackr's web-based application efficiently select relevant abstracts, final list 797 publications aligned with study's objectives. Since advent industrial revolution, gas emissions have witnessed an exponential surge, leading cumulative increase atmospheric temperatures at average rate 0.08 °C (0.14 °F) per decade since 1880. Over past 50 years, has emerged primary heat reservoir, absorbing and distributing majority more than 90% occurring within its waters.

Leveraging built marine structures to benefit and minimize impacts on natural habitats

BioScience, Год журнала: 2025, Номер 75(2), С. 172 - 183

Опубликована: Фев. 1, 2025

Abstract Many natural marine habitats are decreasing in extent despite global conservation and restoration efforts. In contrast, built structures, such as hardened shorelines, offshore energy aquaculture infrastructure, artificial reefs, increasing extent—and, some locations, represent over 80% of nearshore, structured habitat. When introduced into the seascape, structures inevitably interact with habitats, but these not typically designed to support systems. This approach often results overall harm systems, further impeding goals. However, there is growing recognition within ocean management engineering community that can be strategically minimize their negative impacts potentially ecosystems associated biota. We synthesize best available science provide bright spot examples how leveraging mimic or facilitate help recover biodiversity, augment ecosystem services, rehabilitate degraded providing positive outcomes for people nature a changing climate. Despite spots, we caution have environmental consequences should used lieu conventional habitat justify destruction habitats.

Safeguarding marine life: conservation of biodiversity and ecosystems

Reviews in Fish Biology and Fisheries, Год журнала: 2022, Номер 32(1), С. 65 - 100

Опубликована: Март 1, 2022

Marine ecosystems and their associated biodiversity sustain life on Earth hold intrinsic value. Critical marine ecosystem services include maintenance of global oxygen carbon cycles, production food energy, sustenance human wellbeing. However are swiftly being degraded due to the unsustainable use environments a rapidly changing climate. The fundamental challenge for future is therefore safeguard biodiversity, function, adaptive capacity whilst continuing provide vital resources population. Here, we foresighting/hindcasting consider two plausible futures towards 2030: business-as-usual trajectory (i.e. continuation current trends), more sustainable but technically achievable in line with UN Sustainable Development Goals. We identify key drivers that differentiate these alternative develop an action pathway desirable, future. Key achieving will be establishing integrative across jurisdictions sectors), management supports equitable stewardship environments. Conserving require recalibrating our social, financial, industrial relationships environment. While requires long-term planning commitment beyond 2030, immediate needed avoid tipping points avert trajectories decline. By acting now optimise protection ecosystems, building upon existing technologies, conserving remaining can create best opportunity 2030 beyond.

Climate change projections of commercial fish distribution and suitable habitat around north western Europe

Abstract Under future climate change, modification of temperature and salinity are expected to result in distribution shifts marine organisms, including commercial fish shellfish. Changes anticipated everywhere, the seas many important fishing nations. Species turnover will turn both opportunities threats industries. To determine impacts for northwest European shelf fisheries, we project changes 49 commercially shellfish species using an ensemble five ecological niche models three different downscaled change projections. The habitat suitability latitudinal projected from recent past (1997–2016) two futures (2030–2050; 2050–2070) were calculated waters around United Kingdom. Of examined, half have consistently more suitable future, seabass ( Dicentrarchus labrax , Moronidae), sardine Sardina pilchardus Alosidae) anchovy Engraulis encrasicolus Engraulidae).

Climate-driven global redistribution of an ocean giant predicts increased threat from shipping

Nature Climate Change, Год журнала: 2024, Номер 14(12), С. 1282 - 1291

Опубликована: Окт. 7, 2024

Abstract Climate change is shifting animal distributions. However, the extent to which future global habitats of threatened marine megafauna will overlap existing human threats remains unresolved. Here we use climate models and habitat suitability estimated from long-term satellite-tracking data world’s largest fish, whale shark, show that redistributions present-day are projected increase species’ co-occurrence with shipping. Our model projects core area losses >50% within some national waters by 2100, geographic shifts over 1,000 km (∼12 yr −1 ). Greater predicted in current range-edge areas, increasing sharks large ships. This was ∼15,000 times greater under high emissions compared a sustainable development scenario. Results demonstrate climate-induced species exposure direct sources mortality possible, emphasizing need for quantitative climate-threat predictions conservation assessments endangered megafauna.
