Desaparición inminente de osos polares en la Bahía de Hudson por calentamiento global

La población de osos polares en la bahía de Hudson, en el Ártico canadiense, enfrenta una posible desaparición antes de 2030 si no se logra limitar el aumento de la temperatura global a 2 grados, según un reciente estudio publicado en la revista Communications Earth & Environment. La investigación advierte que el cambio climático está afectando gravemente al ecosistema de la bahía, hogar de aproximadamente 1,700 osos polares.

La bahía de Hudson es un punto crítico de biodiversidad donde los osos polares cazan focas en el hielo marino durante el otoño y el invierno. Sin embargo, el calentamiento global ha extendido los periodos sin hielo de 120 a más de 150 días, poniendo en riesgo la capacidad de los osos para cazar y sobrevivir. Los investigadores predicen que si el calentamiento global supera los 2,1 grados, el periodo sin hielo podría prolongarse más allá del límite de supervivencia de los osos polares.

El estudio enfatiza la necesidad de recortar drásticamente las emisiones en la próxima década para evitar la desaparición de estos osos y otras especies dependientes del hielo. La pérdida de nieve y hielo está afectando no solo a los osos polares, sino también a las focas, morsas y caribús que dependen de estos hábitats para su reproducción y migración.
