No one's saying that the disasters that recently happened in Siberia, Australia, northwestern North America, Central Europe, China, etc., are directly caused by climate change, but rather that it aggravates them and considerably increases the probability of them happening.
Nadie dice que los desastres ocurridos últimamente en Siberia, Australia, el noroeste de Norteamérica, Centroeuropa, China, etc sean ocasionados directamente por el cambio climático sino que éste los agrava y aumenta considerablemente la probabilidad de que ocurran.
