Estimates of the impacts of observed climate change during the 20th century obtained by different integrated assessment models (IAMs) are separated into their main natural and anthropogenic components. The estimates of the costs that can be attributed to natural variability factors and to the anthropogenic intervention with the climate system in general tend to show that: 1) during the first ha...

Estimates of the global economic impacts of observed climate change during the 20th century obtained by applying five impact functions of different integrated assessment models (IAMs) are separated into their main natural and anthropogenic components. The estimates of the costs that can be attributed to natural variability factors and to the anthropogenic intervention with the climate system in...

The United Nation’s Sustainable Development Goal Life Below Water (SDG-14) aims to “conserve and sustainably use the oceans, seas, marine resources for sustainable development”. Within SDG-14, targets 14.1 14.2 deal with pollution adverse impacts of human activities on aquatic systems. Here, we present a remote-sensing-based analysis short-term changes in Vembanad-Kol wetland system southwest I...

Metallurgical activities have been undertaken in northern South America (NSA) for millennia. However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the timing of past metal depos...

This chapter outlines the distribution and diversity of wetland resources and examines the types of human activities that have resulted in widespread alteration. The term 'wetland' has a variety of meanings, and examples are given of the terminology used to describe different types of wetlands. The processes responsible for the formation and persistence of wetlands are indicated and considerati...

Emergent plants can be suitable indicators of anthropogenic stress in coastal wetlands if their responses to natural environmental variation can be parsed from their responses to human activities in and around wetlands. We used hierarchical partitioning to evaluate the independent influence of geomorphology, geography, and anthropogenic stress on common wetland plants of the U.S. Great Lakes co...
