캘리포니아 산불 발생 원인


Tonight, the firestorm here in southern California. We’re in San Diego this evening. Hundreds of thousands of Californians are on the run 도주하여. The fires are starting up faster than firefighters can put them out 불을 끄다. NBC Nightly News begins now. This is NBC Nightly News with Brian Williams, reporting tonight from San Diego.

 

As we all know, wild fires in this area are nothing new. In fact, we see them just about every year. As Don mentioned the last benchmark 기준 was that cedar 샌디에고 주변의 과수단지 fire, but this has been the driest season on record, unusually severe. That’s leading some people here to wonder.

 

Are these fires somehow a result of climate change? The UN panel on global warming did warn that we would see more wildfires. So is there a real connection? We’ve asked our chief environmental affairs correspondent Anne Thompson.

 

Wildfires so unusual today may not be in the future. A new study out this week suggests the impact of climate change could be stronger and sooner than expected. And one of the predicted impacts from climate change could be more wildfires. “The study is very disturbing 몹시 염려되는 because it means we’re lunging 돌진하다 forward faster and faster at an accelerating pace, pouring emissions 배기 into the atmosphere 대기 while the earth continues to warm.”

 

China and India’s growing economies are spewing 분출하다 more carbon dioxide 이산화탄소 into the air. And the earth’s forests and oceans are losing their ability to absorb 흡수하다 it. The wildfires are just one example of this fall’s extreme weather. Tornadoes in Michigan. A lack of fall color in the Carolinas. The spectacular foliage muted 색조를 약하게 하다 by drought and warm temperatures. “We’ve been through periods of short droughts, but nothing of this magnitude.”

 

And here in Minnesota’s Twin Cities, they’re still awaiting the first official frost 서리 when the temperature dips 내려가다 to 32 degrees. It should’ve happened two weeks ago. But not this year. So does all this add up to global warming? Scientists say you can’t answer that question after just one season. “The weather we’ve seen this fall may or may not be due to the global warming trend. But certainly it’s a clear picture of what the future is going to look like if we don’t act quickly to cut emissions of the greenhouse gases.” A stark 뚜렷한 warning in this autumn of change.
