過去幾十年中，在美國的西部各州，有更多森林大火發生，影響的區域更廣。科學家發現，氣溫升高、冰雪提早融化都跟野火肆虐有關係。由於冰雪提早融化，森林地帶變得更乾燥，而且乾燥時間變長，增加了起火的可能性。

Over the past few decades, western states in the United States, there are more forest fires occurred, affecting a wider area. Scientists have found that rising temperatures, ice and snow melting earlier related to wildfires raging relationship. As the snow and ice melting earlier, forest areas become drier, and drying time, increasing the likelihood of fire.

Over the past few decades, more forest fires have occurred in the western states of the United States, affecting a wider area. Scientists have found that rising temperatures and early melting of ice and snow are linked to wildfires. As ice and snow melt early, forest areas become drier and dry longer, increasing the likelihood of fire.
