“…Such records are particularly important for remote mountain regions where long-term records are otherwise unavailable and provide insights into regional variations of global warming. Sub-fossils of chironomids, which are particularly sensitive to temperature changes, have been used to infer past air temperatures and show that in many mountain regions temperatures have increased rapidly over the last century (Battarbee et al, 2002;Solovieva et al, 2005;Reinemann et al, 2014b;Williams et al, 2016;Porinchu et al, 2017). In the southern mountains of Costa Rica, sub-fossil chironomids quantified late-Holocene thermal variability including evidence for the Little Ice Age as well as changes in lake level caused by drought (Wu et al, 2017).…”

Mountain lakes are often situated in protected natural areas, a feature that leads to their role as sentinels of global environmental change. Despite variations in latitude, mountain lakes share many features, including their location in catchments with steep topographic gradients, cold temperatures, high incident solar and ultraviolet radiation (UVR), and prolonged ice and snow cover. These characteristics, in turn, affect mountain lake ecosystem structure, diversity, and productivity. The lakes themselves are mostly small and shallow, and up until recently, have been characterized as oligotrophic. This paper provides a review and update of the growing body of research that shows that sediments in remote mountain lakes archive regional and global environmental changes, including those linked to climate change, altered biogeochemical cycles, and changes in dust composition and deposition, atmospheric fertilization, and biological manipulations. These archives provide an important record of global environmental change that pre-dates typical monitoring windows. Paleolimnological research at strategically selected lakes has increased our knowledge of interactions among multiple stressors and their synergistic effects on lake systems. Lakes from transects across steep climate (i.e., temperature and effective moisture) gradients in mountain regions show how environmental change alters lakes in close proximity, but at differing climate starting points. Such research in particular highlights the impacts of melting glaciers on mountain lakes. The addition of new proxies, including DNAbased techniques and novel stable isotopic analyses, provides a gateway to addressing novel research questions about global environmental change. Recent advances in remote sensing and continuous, high-frequency, limnological measurements will improve spatial and temporal resolution and help to add records to spatial gaps including tropical and southern latitudes.

“…The climate change' influence on the aquatic ecosystem in the western region of the United States of America has been interpreted by analyzing the Linkins and Grizzly Lakes microfossils, in which the rate and the magnitude of fauna renewal observed in the early 20th century exceeded those observed in the older samples, resulted from the organic production increasing due to warming process (PORINCHU, HASKETT, et al, 2017).…”

“…Human interactions with each other and with the environment have been responsible for abrupt changes at a regional scale, for example, those observed in lacustrine and fluvial environments (CHIN, BEACH, et al, 2017, PORINCHU, HASKETT, et al, 2017, SCHMIDT, GONZALEZ, et al, 2018. The increasing Greenhouse Gas (GHG) emissions after the industrial cycle are pointed out as the primary cause vector, and it has become the subject of international negotiations in which several countries have committed to the climate mitigation challenge.…”

Climate change review and the CCS technology contribution to the climate mitigation challenges

The main issue in this century were the increasing greenhouse gases (GHG) emissions after the industrial cycle, and it became international concerns related to climate mitigation challenges. Thus, our focus is to discuss a historical view between climate change diagnosis and how carbon capture and storage (CCS) technology may contribute to mitigate climate change challenges. Our methodology is a literature review of technical and economic questions of CCS and the analysis based on geological data. Results show anthropogenic GHG sources’ geological view from chronologic era highlighted how human interaction with the environment climate conditions, and international climate agreements may encourage changes in new legal, institutional, and normative frameworks under jurisdictions and deal with the challenges for implementing CCS technology via soft power. Therefore, we conclude that governments are responsible for arbitrating and establishing the available resources, the interests between the groups, adjusting costs over time to those they will fund.

“…A influência das mudanças climáticas sobre o ecossistema aquático na região oeste dos Estados Unidos da América tem sido interpretada através da análise dos microfósseis Linkins e Grizzly Lakes, nos quais a taxa e a magnitude da renovação da fauna observada no início do século XX superou as das amostras mais antigas, resultando o aumento da produção orgânica devido ao processo de aquecimento (PORINCHU, HASKETT, et al, 2017). Outro exemplo são as mudanças no uso e ocupação do solo que podem levar a modificações relevantes em cursos fluviais.…”

“…As interações humanas entre si e com o meio ambiente têm sido responsáveis por mudanças abruptas em escala regional, tais com observadas em ambientes lacustres e fluviais, e as emissões de Gases de Efeito Estufa (GEE) após a industrialização global são apontadas como o principal seu vetor, sendo objeto de negociações internacionais nas quais diversos países se comprometeram a enfrentar o desafio da mitigação climática (CHIN, BEACH, et al, 2017, PORINCHU, HASKETT, et al, 2017, SCHMIDT, GONZALEZ, et al, 2018.…”

Mudanças climáticas e a contribuição da tecnologia de CCS para os desafios da mitigação do clima

Resumo O principal desafio recente tem sido o problema das emissões de e gases de efeito estufa (GEE) pós-industrialização, e que se tornou objeto de esforços internacionais no intuito de mitigar os efeitos de mudança climática. Esse trabalho visa discutir o tema principal sob ótica das mudanças geológicas de longo prazo, e como a tecnologia de captura e armazenamento de carbono (CCS) pode contribuir para a resolução do desafio climático global. A metodologia baseia-se em revisão literária do CCS e de dados geológicos. O resultado mostra que a atividade humana quanto à GEE tem sido o vetor da definição do Antropoceno como era geológica, e acarretou preocupações políticas e acordos internacionais do clima, que encorajam aperfeiçoamentos legal, institucional e normativo para lidar com desafios da implementação do CCS. Conclui-se pela responsabilidade do poder público como agente que arbitra regras e estabelece recursos disponíveis, interesses envolvidos e ajustes de custo.
