The organic matter preserved in lake sediments holds valuable information for reconstructing past environmental conditions. Researchers from Université Quisqueya in Haiti utilized this approach to analyze a core sample from Lake Azuei, considering the past 1000 years.   They divided the core into five time periods and analyzed the amount and type of organic matter present in each layer.   The results revealed changes in organic matter deposition that reflected both climate fluctuations and human activity in the surrounding area. During drier periods, such as the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA), less organic matter accumulated in the sediment, likely due to reduced water levels and plant growth. Conversely, wetter periods displayed higher organic matter content. This pattern held true for the period between the MCA and LIA, as well as the Current Warm Period (CWP) and the MCA2. The analysis also identified an increase in organic matter in recent times, like

  Climate change is a complex phenomenon with multiple implications, affecting countries to varying degrees depending on their infrastructure and response capabilities. The Intergovernmental Panel on Climate Change (IPCC) has confirmed the existence of evidence of the effects of human activities on health, with estimates predicting an increase in global morbidity related to climate change. The issue of climate-induced migration is complex and controversial. The World Bank report "Groundswell" anticipates 140 million internal climate migrations by 2050 in sub-Saharan Africa, South Asia and Latin America, while the IOM estimates that there were 272 million climate migrants in 2019. This summary focuses on the psychological consequences of climate displacement on affected populations. It analyzes the social representations of the stress experienced by displaced persons following Major Climate Events (MCs) and its impacts on their lives. Haiti is particularly vulnerable to cl
