Havana, Jan 30 (Prensa Latina) A research project allowed to detect the occurrence in Cuba, during the last 12,500 years, of warm and cold events which were not recorded so far in the Caribbean country, reflected the Granma newspaper. Under the guidance of Professor Jesus M. Pajon Morejon, research curator of the department Paleogeography and Paleobiology, of the National Museum of Natural History of Cuba, the Paleoclimates Paleohuricanes project in Cuba is running for over five years.
The initiative is part of the National Climate Change Program in Cuba. Impacts, Adaptation and Mitigation, and involves specialists from the Institute of Meteorology.
The scientist emphasized that integrated studies of past climate are, along with contemporary research on the subject, knowledge needed to improve forecasting models on the evolution of the climate in the short, medium and long term.
At the same time, they help distinguish between changes caused by natural variation in environmental conditions of the planet and those induced by human activity.
The research, developed with stalagmites in caves located in the province of Pinar del Río, required advanced methods and techniques of analysis of laboratories in collaboration with experts from the Academy of Sciences of Heidelberg, Germany, which included absolute dating and analysis of stable oxygen isotopes.
Evidence were found of the Little Ice Age, which occurred particularly in Europe between 1350 and 1800, and the occurrence of the medieval warm and humid climatic anomaly, known as Medieval, Climate Optimum between the 700 and 1300, among other findings.
The research has practical application in short-term programs, strategies and national environmental management policies and in studies of the impacts of climate change in the Cuban society, with potential use throughout the Antilles Caribbean.
