Resumen
El cambio climático es un proceso que impacta en todos los sistemas socio-ambientales, adquiriendo rasgos específicos en cada región. Para comprender y proyectar apropiadamente el alcance de dicho impacto, se requiere de un ejercicio conjunto entre los especialistas de las disciplinas involucradas. La comunidad científica internacional viene desarrollando diversos conjuntos de datos para el estudio de la variabilidad y del cambio climático, e ideando estrategias apropiadas para su tratamiento. Sin embargo, se observa una tendencia disciplinaria, hacia el uso de una única fuente de datos climáticos, ya sea por simplicidad o porque cumple con los requisitos de resolución o disponibilidad en el formato deseado. En este sentido, los climatólogos observan con preocupación el uso acrítico de las bases de datos climáticos. A partir de esta preocupación, surge este artículo que tiene como objetivo describir tanto los alcances como las limitaciones de las bases de datos disponibles. Además, se aborda la problemática de la incertidumbre en las proyecciones climáticas y se proporciona información sobre cómo utilizar los datos climáticos para llevar a cabo experimentos relacionados con la distribución de especies, teniendo en cuenta la incertidumbre inherente a los datos. Se destaca la importancia de realizar múltiples experimentos conducidos por N-proyecciones climáticas independientes, y de utilizar herramientas estadísticas para concluir sobre la base de una serie de posibles soluciones.
Climate change is a complex phenomenon that affects all socio-environmental systems, manifesting itself uniquely in different regions. To comprehensively understand and project the extent of its impact, it is crucial to engage in a collaborative effort involving specialists from various disciplines. The international scientific community has made significant progress in developing diverse datasets for studying climate variability and change, along with the formulation of suitable methodologies for their analysis. However, there is a tendency within certain disciplines to rely solely on a single source of climate data, either for the sake of simplicity or due to its compatibility with desired resolution or availability requirements. In this context, climatologists express their apprehension regarding the uncritical utilization of climate databases. It is from this concern that the present article aims to provide a comprehensive description of the scope and limitations associated with the available databases. Furthermore, the article addresses the issue of uncertainty in climate projections and offers guidance on how to effectively employ climate data in conducting experiments pertaining to species distribution, while considering the inherent uncertainty associated with such data. Emphasis is placed on the significance of conducting multiple experiments utilizing independent climate projections, as well as utilizing statistical tools to draw conclusions based on a range of potential solutions. By adopting this approach, researchers can more effectively assess the impact of climate change and its implications for species distribution patterns.
