Is Extreme Weather Related to Climate Change ?
Wild weather, freakish weather, really hot, really cold, really rainy, really snowy.
Seems to be happening more frequently these days.
Is it because of climate change?
Before we answer that question we have to clear something up.
The difference between weather and climate.
Weather is what's happening in the atmosphere on a specific day in a specific location.
Things like temperature, wind, precipitation.
Climate is the general condition of the atmosphere over a much broader region over decades of time.
Conditions such as warm or cold or wet or dry.
However it only takes a small change in the climate like a little global warming to create a big change in the weather.
If the rainfall in New York and Boston is above average one year, we might just chalk it up to a normal fluctuation in the weather.
But if rainfall stays above average for years on end then the climate is changing.

恶劣的天气，异常的天气，非常热，非常冷，多雨，多雪。
最近这种事似乎越来越频繁了。
是因为气候变化吗?
在回答这个问题之前，我们必须澄清一些事情。
天气和气候的区别。
天气是在特定的一天在特定的地点在大气中发生的事情。
比如温度，风，降水。
气候是一个更广阔的区域在几十年的时间里大气的一般状况。
比如温暖、寒冷、潮湿或干燥的环境。
然而，只需要一个小的气候变化，比如一点全球变暖，就能造成天气的大变化。
如果纽约和波士顿的降雨量高于一年的平均水平，我们可以将其视为天气的正常波动。
但如果降雨量连续多年高于平均水平，那么气候就在变化。
In fact scientists have been warning us that the more climate changes the more likely we are to have extreme weather.
We've seen a lot of weird weather events with less than a 2º rise in global temperature.
Research says we can expect more of these events as the Earth gets hotter.
We'll see more tropical rains in dryer areas like tropical storm Irene in August 2011 which put Northeastern New York and Southern Vermont under water.
Warmer atmosphere can hold more moisture so more moisture can precipitate out during a storm.
We'll see more prolonged heat waves and droughts like the ones that hit Texas in 2011.
That was the states worst drought in history and the temperature hit 100º in Dallas on more than 60 days.
We can expect long periods of spring time temperatures during the winter, like the extended warmth that hovered over the Eastern US in January 2012 and again in March and ironically unusually cold and snowy conditions in winter too, like the snowmageddon that clobbered Washington DC in 2010.
So that sums up our long range forecast: Change the climate and you change the weather.

sentence:
事实上，科学家一直在警告我们，气候变化越大，极端天气发生的可能性就越大。
我们已经看到了很多奇怪的天气事件，全球气温上升不到2º。
研究表明，随着地球变热，我们可以期待更多这样的事件。
我们将在干旱地区看到更多的热带降雨，比如2011年8月的热带风暴艾琳，它将纽约东北部和佛蒙特州南部淹没在水中。
温暖的大气可以容纳更多的水分，因此更多的水分可以在风暴中沉淀出来。
我们将看到更多像2011年袭击德克萨斯州的热浪和干旱。
这是美国历史上最严重的干旱，达拉斯的气温在60多天里达到了100华氏度。
在冬季，我们可以预期很长一段时间的春季气温，就像2012年1月和3月徘徊在美国东部的持续温暖，具有讽刺意味的是，冬季也异常寒冷和多雪，就像2010年袭击华盛顿特区的雪灾。
以上总结了我们的长期预测:改变气候就会改变天气。
