Removal of Dyestuffs from Effluents onto Biochar
Processing significant amounts of dye effluent discharges into receiving waters can supply major benefits to countries that are affected by the water crisis and anticipated future stress in many areas in the world. When compared to most conventional adsorbents, biochars can provide an economically attractive solution. In comparison to many other textile effluent treatment processes, adsorption technology provides an economical, easily managed, and highly effective treatment option.

Late Glacial Interstadial
The Late Glacial Interstadial (LGI) c.14,670 to c.12,890 BP represents the first pronounced warming since the end of the Last Glacial Maximum (LGM). Human populations, which had previously forced into refuge areas, gradually begin to repopulate the Northern Hemisphere's Eurasian landmass and eventually populate North America via Beringia for the first time. Evidence for its occurrence stems from two main types of analysis. The first is the use of oxygen isotope stages (OIS) gathered from stratified deep-sea sediment cores. Samples are gathered and measured for change in isotope levels to determine temperature fluctuation for given periods of time. The second is a proxy measurement, the observation of certain reappearing fauna and flora fossils that can survive only in temperate climates, thus indicating warming trends for a given geographic area. Archaeological evidence of settlement and resettlement in certain areas by humans also serve as proxy measurements. Towards the end of OIS 2 in which the Last Glacial Maximum occurs, the deep-sea sediment cores indicate a gradually warming climate, and the reappearance of certain warm-weather flora and fauna remains throughout the Northern Hemisphere correlate with that trend. The Late Glacial Interstadial was followed by a severe decline in temperatures during the Younger Dryas from c.12,890 to c.11,650 BP.

Reuse of Water Contaminated by Microplastics
Water treatment generally does not specifically address the removal of microplastics (MPs). Nevertheless, treatment plants process water effectively, and the number of synthetic microparticles in effluents is usually very low. Still, discharge volumes from water-treatment plants are often elevated (reaching around 10^8 L/day), leading to the daily discharge of a substantial number of MPs and microfibers. Furthermore, MPs accumulate in the primary and secondary sludge, which in the end results in another environmental problem as they are currently used to amend soils, both for cultivation and forestry, leading to their dispersion. Something similar occurs with the treatment of water intended for human consumption, which has a much lower but still significant number of MPs.

GIS-Based Cropland Suitability Prediction Using Machine Learning
The increasing global demand for food has forced farmers to produce higher crop yields in order to keep up with population growth, while maintaining sustainable production for the environment. The conventional method for calculating cropland suitability in previous studies was a geographic information system (GIS)-based multicriteria analysis, dominantly in combination with the analytic hierarchy process (AHP). Although this is a flexible and widely accepted method, it has significant fundamental drawbacks, such as a lack of accuracy assessment, high subjectivity, computational inefficiency, and an unsystematic approach to selecting environmental criteria.

Air Mercury Monitoring
The GMOS (Global Mercury Observation System) project has the overall goal to develop a coordinated observing system to monitor mercury on a global scale. We present the long-term (2011 – 2020) air mercury monitoring data obtained at the Listvyanka station located at a shore of Lake Baikal, Siberia. The long-term monitoring shows obvious seasonal variation of the background mercury concentration in air, which increases in the cold and decreases in the warm season. The short-term anomalies are associated with the wind carrying the air from the industrial areas where several big coal-fired power plants are located. A positive correlation between the mercury, SO2 and NO2 concentrations is observed both in the short-term variations and in the monthly average concentrations. The analysis of forward and backward trajectories obtained with the HYSPLIT model demonstrates revealing of the mercury emissions sources. During the cruise of 2018, the continuous air mercury survey over Lake Baikal covered 1800 km. The average mercury concentration over Baikal is notably less in comparison with the average value obtained at the onshore Listvyanka station during the same days of cruise. That can lead to the conclusion that Baikal is a significant sink of the atmospheric mercury.

Remote Sensing in Coastal Areas
Coastal areas are regions of remarkable relevance for humans, providing essential components for social and economic development from the local to the national scale. To preserve the economic and ecological sustainability of the coastal environment, the scientific community has been pushing for the use of integrated observation systems aimed at monitoring such susceptible areas. Remote sensing data can complement traditional field measurements, ensuring almost continuous synoptic coverage with a good trade-off between spatial and temporal resolution, thus allowing for a timely characterization of coastal environment dynamics. In particular, the availability of a multi-temporal historical series of remote sensing data can provide useful information on the spatiotemporal variability of hydrological (sea surface currents, river runoff/discharge), biological (phytoplankton blooms, primary productivity) and physical (temperature, salinity, and turbidity) properties of coastal waters as well as on human-induced land cover mutations (deforestation, surface urban islands).  This Special Issue seeks to collect high-quality papers focused on satellite-based applications for monitoring coastal areas, continental shelves and estuarine ecosystems.

Climate Change Education
Climate Change Education (CCE) is one of the initiatives taken to deliver the facts about the current climate status of the world and the proper mitigation actions that need to be done to the youth, as they will be the ones who will have to face and deal with the consequences of climate change.; thus, CCE has now become a critical factor in strengthening the climate change awareness of young people. CCE is one of the sub-areas of Education for Sustainable Development (ESD) where the focus is on the complexity and challenges involved in understanding and responding to the impact of climate change; furthermore, the implementation of CCE in ESD should include a holistic and integrated view of all dimensions, covering the ecological, economic, and social aspects of the consequences of climate change.

Climate-friendly Gardening
Climate-friendly gardening is gardening in ways which reduce emissions of greenhouse gases from gardens and encourage the absorption of carbon dioxide by soils and plants in order to aid the reduction of global warming. To be a climate-friendly gardener means considering both what happens in a garden and the materials brought into it and the impact they have on land use and climate. It can also include garden features or activities in the garden that help to reduce greenhouse gas emissions elsewhere.

Legislative System of Photovoltaic Industry Development in China
As one of the world’s largest energy consumers, China is facing the challenge of growing energy demand. Under this background, China is actively implementing the concept of green development and sustainable development route. As inexhaustible green energy, solar energy, has been established as an independent energy type by the Renewable Energy Law and has a broad development prospect. At present, the industrialization level of photovoltaic manufacturing in China is constantly improving, and the efficiency of photovoltaic power generation is constantly improving. However, from the perspective of the system, China’s photovoltaic industry supporting legal system is not perfect. There is a mismatch between the existing laws and industrial development needs, which restricts the future development of photovoltaic power generation in China. The legal environment is crucial to the development of a country’s relevant industries. Only with a good supporting legal system can the development and utilization of solar energy be carried out reasonably and orderly. The PV industry legislation should be adjusted and responded to in a timely manner according to the development situation of the PV industry and the PV market, so as to speed up the introduction of core laws in the PV field, continuously improve the supporting legal system, and effectively play the role of institutional protection of the law.

Revalorization of Microalgae Biomass for Synergistic Interaction
Microalgae and cyanobacteria are photosynthetic microorganisms’ sources of renewable biomass that can be used for bioplastic production. These microorganisms have high growth rates, and contrary to other feedstocks, such as land crops, they do not require arable land. In addition, they can be used as feedstock for bioplastic production while not competing with food sources (e.g., corn, wheat, and soy protein).

Environmental Sorption of Additives from Microplastics
Although the impacts of plastic pollution have long been recognized, the presence, pervasiveness, and ecotoxicological consequences of microplastic—i.e., plastic particles < 5 mm—contamination have only been explored over the last decade. Far less focus has been attributed to the role of these materials and, particularly, microplastics, as vectors for a multitude of chemicals, including those (un)intentionally added to plastic products, but also organic pollutants already present in the environment.
