Procyon B es una enana blanca, que es una etapa tardía en el ciclo de vida de una estrella. Las otras estrellas mencionadas no están en esta etapa tardía.

Si el hielo antártico se derrite debido al calentamiento global, el nivel del mar subirá. Esto causará inundaciones en áreas costeras como Long Island, New York.

El aire frío en la Antártida no puede contener mucha humedad. Cuando el aire frío se enfría aún más, la humedad se condensa y cae como nieve, pero la cantidad de humedad disponible es baja, lo que resulta en una baja precipitación.

Answer:

b. Procyon B
