The direct impacts of climate change involve a multitude phenomena, including rising sea levels, intensified severe weather events such as droughts and flooding, increased temperatures leading to wildfires, unpredictable fluctuations in rainfall. This comprehensive review intends examine firstly the probable consequences on extreme drought, flood wildfire. subsequently examines release transformation contaminants terrestrial, aquatic, atmospheric environments response driven by change. While drought influence dynamics inorganic organic terrestrial aquatic environments, thereby influencing their mobility transport, wildfire results spread atmosphere. There is nascent awareness change's change-induced environmental scientific community decision-making processes. remediation industry, particular, lags behind adopting adaptive measures for managing contaminated affected events. However, recognizing need assessment represents pivotal first step towards fostering more practices management environments. We highlight urgency collaboration between chemists experts, emphasizing importance jointly assessing fate rigorous action augment risk strategies safeguard health our environment.

Understanding the impact of land use change on ecosystem service values (ESV) will provide a valuable reference for formulation and implementation ecological restoration programs (ERPs) policies. The Guizhou Province is typical karst region with fragile in southwest China. During past decades, multiple ERPs, especially Grain Green Program (GFGP), have been implemented this region, which has resulted dramatic change. However, how ESV responded to remains unclear. Moreover, few studies addressed response different intensities ERPs future. This study adopted benefit transfer method quantitatively evaluate contributions transitions from 2000 2020. we designed three GFGP scenarios explore intensity identify priority areas. results showed that total experienced net increase 10.64 billion USD 2020, was mainly attributed expansion forestland water area. transition farmland loss 5.07 ESV, accounting 53.66% loss, should receive enough attention. by 17.07 USD, 30.16 48.58 under mild GFGP, moderate strong scenarios, respectively. high-intensity enhanced trade-off relationship between provision services other kinds (i.e. regulating services, culture habitant services). scenario converting slope greater than 20° into forestland) optimal Zunyi, Bijie, Qiandongnan be areas implement taken consideration suitable determined based local characteristics GFGP. can references formulating optimizing policy Province.

Quantitatively revealing the response of carbon stocks to land use change (LUCC) and analyzing vulnerability ecosystem stock (ECS) services are great significance for maintaining cycle ecological security. For this study, China’s Guizhou Province was study area. Land data in 2000, 2010, 2020 were selected explore impacts LUCC on multiple scenarios by combining PLUS InVEST models then ECS services. The results show that forest plays an important role improving karst plateau mountainous areas. In 2000–2020, expansion offset reduced built-up land, greatly regional function. Following natural trend (NT), total will decrease 1.86 Tg; however, under protection (EP) measures, service performs a positive function LUCC. Focusing socioeconomic development (ED) increase service. future, area size should be increased, restricted better improve
