Mega sequía en California

Azota desde hace dos décadas al suroeste de América del Norte y es la peor de los últimos 1.200 años.

Los efectos del cambio climático están avanzando a un ritmo que nadie podría haber anticipado.

California está ingresando a su tercer verano consecutivo de una dolorosa sequía.

Una investigación publicada en febrero de este año mostró que la temporada de sequía actual está relacionada con una mega sequía más larga, que ha persistido desde el año 2000.

Según el estudio, se debe al cambio climático causado por el hombre.

La sequía se manifiesta en varias formas:

■ Suministros comunitarios insuficientes o ecosistemas en dificultades

■ Disminución de precipitaciones

■ Bajos niveles de agua subterránea y de arroyos

■ Cultivos sedientos

Los expertos advierten que requerirá más que un solo invierno húmedo para compensar el déficit actual de agua.
