The Ministry of Truth speaks :
It reflects a new reality: The coldest day of the year isn’t as cold as it used to be, so some plants and trees can now survive farther north.
“People who grow plants are well aware of the fact that temperatures have gotten more mild throughout the year, particularly in the wintertime,” said Boston University biology professor Richard Primack.
Over the past decade, US winter temperatures have been dropping at a rate of more than 40 degrees per century.

How can you beat scientific terms such as: “like it used to be”?
I have been growing plants and trees for longer than most of those writing that shit have been alive. I can say from experience the do not know WTF they are talking about.
I discussed local weather conditions with people older than I am that were raised on farms and they also say those idiots are FOS!
