The main objective of the researches carried was obtaining scientific knowledge that contribute to the study of climatic variability of key sectors of Cuban archipelago during Late Pleistocene-Holocene, considering long-period paleoregisters due to the natural tendencies of climate, as the historical and instrumental short-period paleoregisters that include environmental anthropic action.

Some of the most significant contributions are the following:

• Obtaining curves of paleotemperatures, which show a wide climatic variability and a tendency to the increase of temperatures from the Maximum Last Glacial (UMG-18 000 years) to the present;
• Realizing paleoclimatic studies that show a difference of temperatures of 8-10 C between the UMG and the present Interglacial, for mountain sectors of Western Cuba;
• Detecting an Abrupt Climatic Heating 11 520+ 50 years ago approximately, which caused an increase of temperatures of 6-8 C, only in 2000 years, an incrase of 1.5-2 C in the last 200 years and an increase of the variability of precipitations;
• Assessing the rate of sea increment in Cuba for the last 30 years, which is from 0.2 to 0.3 cm/year; and it was created a map of Cuban soils' carbon reserves, for the last 3 000 years to the present.

The results obtained have been published in specialized international magazines and they contritute to the National Program of Global Changes and the Evolution of Cuban Environment, as well as to Programs and International Projects such as the Project of Global Changes in the Past (Pole-Ecuador-Pole Project) and Paleoclimate of America of International Geosphere and Biosphere Program (IGBP).
