极寒天气反而是全球变暖的证明

本周二，美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）一次冰冷的回击仿佛借用了美国中西部地区的寒意。

这次批评是对唐纳德·特朗普总统有关全球变暖的不当言论的回应。尤其是特朗普还声称，考虑到最近严寒的气候模式，全球变暖根本不存在。

特朗普在周一发表推文，讽刺地表示：“在美丽的中西部地区，风寒相当温度已经达到零下60华氏度。全球变暖是怎么回事？（推文中还把warming错拼成waming）快点来吧，我们需要全球变暖！”

在美丽的中西部地区，风寒相当温度已经达到零下60华氏度，是有记录以来的最低温度。接下来几天甚至会更加寒冷。人们甚至无法在户外坚持几分钟。全球变暖是怎么回事？快点来吧，我们需要全球变暖！

美国国家海洋和大气管理局是总统这番误导性言论的众多批评者之一，该机构发布了一张有趣的照片和一个链接。链接里是他们在2015年写的文章，解释了为什么“冬季的风暴并不证明全球变暖不存在”。

该机构在题为《创纪录的暴风雪是否证明全球变暖并不存在？》的文章中写道：“变暖的气候下不仅可能出现严重的暴风雪，而且出现的概率甚至会更高。”他们言简意赅地回答了这个问题：“不。”

美国国家海洋和大气管理局解释道，特朗普所指的酷寒暴风雪可能是因为海洋温度升高所致。

美国国家海洋和大气管理局写道：“这些猛烈的风暴大多源于陆地寒冷空气与海洋湿热空气的强烈差异。海洋温度升高，可能会让海上空气更温暖、更潮湿，这加剧了差异。这些潮湿空气随后被卷入风暴系统，产生了大量降雪。”

这不是特朗普第一次对全球变暖提出质疑，而他的说法引发的怒火不仅仅来自联邦机构。

正如“只是又一个18岁青年”所说：

我比您小了54岁。我刚刚以平均分数完成了高中课程。但即使是我都能告诉您天气与气候不是一回事。如果您需要帮助才能理解这一点，我可以借给您我2年级时买的百科全书。上面有配图和一切信息。

The National Oceanic and Atmospheric Administration (NOAA) borrowed some of the Midwest’s arctic chill in an ice cold clapback on Tuesday.

The criticism was in response to President Donald Trump’s inaccurate assertion about Global Warming—specifically, his implication it doesn’t exist given recent freezing cold weather patterns.

“In the beautiful Midwest, windchill temperatures are reaching minus 60 degrees, the coldest ever recorded,” Trump tweeted Monday, sarcastically asserting, “What the hell is going on with Global Waming [sic]? Please come back fast, we need you!”

In the beautiful Midwest, windchill temperatures are reaching minus 60 degrees, the coldest ever recorded. In coming days, expected to get even colder. People can’t last outside even for minutes. What the hell is going on with Global Waming? Please come back fast, we need you!

The NOAA was one of many critics of the President’s misinformed statement, tweeting a delightful illustration and a link to one of the agency’s 2015 articles explaining how “Winter storms don’t prove that global warming isn’t happening.”

“Not only are severe snowstorms possible in a warming climate, they may even be more likely,” the agency wrote in its piece that asks “Are record snowstorms proof that global warming isn’t happening?” in its headline, and answers the question in the one-worded lede: “No.”

The NOAA explains that the freezing snowstorms to which Trump is referring could be due to the rising ocean temperature.

“These storms draw much of their intensity from the extreme contrast between cold air over land and warmer, wetter air from over the ocean,” the NOAA writes. “Warmer ocean temperatures may make the air aloft warmer and moister, amplifying the contrast. That wetter air is then brought into the storm system, producing large amounts of snow.”

This isn’t the first time Trump has questioned global warming, and his assertions haven’t only drawn ire from federal agencies.

As “just another 18-year-old” put it:

I am 54 years younger than you. I just finished high school with average marks. But even I can tell you that WEATHER IS NOT CLIMATE. If you want help understanding that, I can lend you my encyclopedia from when I was in 2nd grade. It has pictures and everything.

It’s ice cold both outside and on the internet today.
