Earth Day is celebrated every year on April 22nd, and it is a global event aimed at raising awareness and promoting action towards environmental protection. It was first celebrated in 1970, and since then, it has become one of the largest civic events in the world, with over one billion people participating in activities such as clean-up campaigns, tree-planting initiatives, and educational programs. The theme for 2023 is Invest in Our Planet, a campaign that will focus on engaging governments, institutions, businesses and individuals in the fight against the climate crisis.
This study shows downscaled climate projections that, without strong curbing of emissions, the California Current System (CCS) will undergo significant change this century, including 2–4 °C warming of sea surface temperature and an almost ubiquitous shift to novel conditions
This paper show the mathematical and theoretical background of the machine learning algorithm used in this work, the LSTM. The data used are described and the methodology of framework is presented. It shows the predictions results based on LSTM and comparisons with ERA5 and buoy observations.
This paper based on three implemented Regional Climate Models (RCMs), namely CMCC-CCLM, CNRM-ALADIN52, and GUF-CCLM-NEMO, for RCP4.5 and RCP8.5 scenarios of the 21st century. Atmospheric modelling datasets cover the Reference (1971–2000) and Future (2071–2100) Periods of climate projections. The results produced within this study can be used for investigations in specific locations of the Mediterranean basin within integrated hydrologic/hydrodynamic modelling under projected climate change conditions during the 21st century.
Clean water resources are crucial for societies in order to maintain safety as well as social, ecological and economic progress. As the population grows, agricultural, domestic and industrial activities produce large amounts of wastewaters that can be treated and reused in variety of purposes considering circular economy philosophy. This review presents the challenges and future prospects of wastewater treatment using membrane technologies and is related to SDG 6: Clean water and sanitation.
This paper provides first assessment of nutrient contents in whale faeces prior to their dissolution in seawater, which has overcome the challenges associated with getting reliable estimations of elemental nutrients from whale faeces. By combining measured faecal nutrient concentrations with the best available prey-consumption and prey-assimilation estimates, we calculated the expected contribution of minke whale faeces to nutrient pools in surface waters during summer.
This article focuses on a key industry in ocean governance - tuna fishery - to examine how companies and governments relationship in international fishery negotiations can influence the governance of tuna fishery industry.
As growing coastal societies and projected high population densities predict a larger demand for marine ecosystem services in the future, jellyfish may affect the fulfillment of such needs, thus becoming prominent players in provisioning, cultural, and supporting services. Hence, our results advocate for their inclusion in multidisciplinary research beyond regional scales and call for investing in this group through systematic surveys.
Offers practical insights to guide shipping industry managers to introduce environmentally responsible and sustainable practices.
