本周二，美國國家海洋和大氣管理局（National Oceanic and Atmospheric Administration, NOAA）一次冰冷的回擊仿佛借用了美國中西部地區的寒意。

這次批評是對唐納德·特朗普總統有關全球變暖的不當言論的回應。尤其是特朗普還聲稱，考慮到最近嚴寒的氣候模式，全球變暖根本不存在。

特朗普在周一發表推文，諷刺地表示：“在美麗的中西部地區，風寒相當溫度已經達到零下60華氏度。全球變暖是怎么回事？（推文中還把warming錯拼成waming）快點來吧，我們需要全球變暖！”

在美麗的中西部地區，風寒相當溫度已經達到零下60華氏度，是有記錄以來的最低溫度。接下來幾天甚至會更加寒冷。人們甚至無法在戶外堅持幾分鐘。全球變暖是怎么回事？快點來吧，我們需要全球變暖！

美國國家海洋和大氣管理局是總統這番誤導性言論的眾多批評者之一，該機構發布了一張有趣的照片和一個鏈接。鏈接里是他們在2015年寫的文章，解釋了為什么“冬季的風暴并不證明全球變暖不存在”。

該機構在題為《創紀錄的暴風雪是否證明全球變暖并不存在？》的文章中寫道：“變暖的氣候下不僅可能出現嚴重的暴風雪，而且出現的概率甚至會更高。”他們言簡意賅地回答了這個問題：“不。”

美國國家海洋和大氣管理局解釋道，特朗普所指的酷寒暴風雪可能是因為海洋溫度升高所致。

美國國家海洋和大氣管理局寫道：“這些猛烈的風暴大多源于陸地寒冷空氣與海洋濕熱空氣的強烈差異。海洋溫度升高，可能會讓海上空氣更溫暖、更潮濕，這加劇了差異。這些潮濕空氣隨后被卷入風暴系統，產生了大量降雪。”

這不是特朗普第一次對全球變暖提出質疑，而他的說法引發的怒火不僅僅來自聯邦機構。

正如“只是又一個18歲青年”所說：

我比您小了54歲。我剛剛以平均分數完成了高中課程。但即使是我都能告訴您天氣與氣候不是一回事。如果您需要幫助才能理解這一點，我可以借給您我2年級時買的百科全書。上面有配圖和一切信息。

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.
