Construction of a Comprehensive International Legal Protection Mechanism for Climate Refugees
Climate refugee has become an unavoidable major right crisis challenge for the international community. However, the corresponding development of positive international law is obviously imperfect. The basic rights of climate refugees cannot be fully guaranteed by international law. They are always facing problems such as unclear legal status lack of protection of basic rights, and imperfect relief mechanism. Those vulnerable groups who lack resources and migration abilities suffer more serious rights violations because they are forced to stay in place. Compared with the risk-management framework and right-protection framework, the comprehensive international legal protection mechanism is the inevitable choice for climate refugees’ rights relief in the post-2012 period. The rights of climate refugees set out in the preamble of the Paris Agreement in 2015, the New York Declaration on Refugees and Migrants in 2016, the Global Refugee Compact in 2018, and the Global Compact for Security, Order and Regular Migration formally incorporated the issues of refugees and migrants caused by climate change, laying the foundation for this choice. However, it is a long and difficult way to build a perfect comprehensive international response to climate change. It is not only necessary to realize the integration of human rights law and climate law at the conceptual level, but also to integrate the different perspectives of the two laws and build a set of scientific and reasonable cooperation mechanism.
A polycrystalline Cantor alloy, equimolar in Co, Cr, Fe, Mn and Ni, was cast. It was subjected to oxidation in a thermo-balance in a flow of synthetic dry air, at 1000, 1050, 1100 and 1150 °C. The mass gain was globally parabolic but rather irregular. The parabolic constants, ranging from 55 to 700 × 10−12·g2·cm−4·s−1, are much higher than for a chromia-forming alloy. They obey an Arrhenius law with an activation energy equal to 270 kJ/mol. The external oxide scales formed are composed of an outer part made of manganese oxide and an inner part made of (Cr, Mn) oxide containing a thin internal layer of chromia. The Mn and Cr-depleted depths and the Mn and Cr masses lost by the alloy increase with the oxidation temperature. Cr-rich acicular particles precipitated in subsurface at 1100 °C and internal oxidation along the grain boundaries are present in the whole thickness of the sample oxidized at 1150 °C. Oxide spallation occurred during the cooling, at temperatures in the 200–350 °C range, only for the alloys oxidized at 1050 and 1100 °C. Not too thick scale (1000 °C) or deep internal oxidation (1150 °C) may be favorable for scale adherence.
This paper offers a review of bioarchaeological research on human mobility during the Hellenistic and Roman period in the Central and Eastern Mediterranean. This period was marked by significant connectivity amidst the establishment of major political entities. The paper begins with an overview of bioarchaeological methods used to study past mobility, including biodistance, isotopic and ancient DNA analyses. It then examines published studies that have utilized these methods to explore mobility during the Hellenistic and Roman periods. The paper concludes by critically assessing the current research limitations and proposing directions for future studies. These suggestions emphasize the importance of conducting additional research to investigate human mobility in neglected areas, as well as at different temporal and spatial scales. Integrating mobility data with other sources of evidence, such as historical accounts, paleoenvironmental data and osteobiographic information is another important future direction of research. Finally, relevant research should be more theoretically informed and its contemporary implications should be effectively communicated within and beyond the academic community. An enhancement of our understanding of the nature and impact of mobility is crucial in today’s society, where misconceptions linking immigration to the decline of the Roman Empire can perpetuate biases against contemporary mobility.
The occupation of the Amazon is driven by capitalist production, impacting climate change discussions. Despite constitutional protections since 1934, the influx of non-Indigenous settlers, particularly miners, led to significant conflicts. The Yanomami sought international recourse through the Inter-American Commission on Human Rights (IACHR). In the context of redemocratization, the 1988 Constitution marked a shift, reinforcing Indigenous rights and environmental protection. Brazil’s role in protecting the rainforest intersects with global climate efforts, including the REDD+ mechanism. The creation of the Amazon Fund in 2008, aligned with REDD+ initiatives, involved international cooperation and local governance, leading to a substantial decline in Amazon deforestation between 2004 and 2012. However, exploitative practices endorsed by the State pose threats to environmental and human rights, notably affecting indigenous communities. Amid Brazil’s democracy crisis, deforestation surged in the Amazon from 2013–2022 and the Yanomami face conflicts fueled by State support for non-Indigenous groups. The Yanomami sought international recourse through the IACHR and the Inter-American Court of Human Rights. These issues are intensified by an ideological bias, linked to authoritarian populism rooted in the legacy of the Dictatorship. Recent initiatives aim to enhance environmental and human rights protection. However, political instability poses challenges for the future.
