Cacti thrive in temperatures between about 4C to 26C and are quite happily growing out doors throughout the year in Canada and Alaska. Don’t be so alarmist. It helps nobody.

Yeah I have cacti growing in my backyard that get covered in feet of snow in the winter and stay covered for weeks at a time. This article is stupid.

It snows in the Arizona desert, all over the damn cactus.

They address this in the article. Besides maybe the headline, what exactly is alarmist?

Good news everyone! A species of prickly pear cactus (Opuntia polyacantha) can survive temperature as low as -46°C! So good news, almost everyone can grow nopales at home!

Aluminum gets hotter in the sun, colder in the winter.

How? I thought cacti were native to only the Americas?

Edit: I'm stupid and didn't read the article yet

The Guardian isn't a good source for anything but proganada and fear porn..

Some Opuntias can survive a lot of winter. They have been in the wild (and spreading on their own) in Hungary too. Lack of rain might be an even bigger problem than rising temperatures, as long dry periods might give the cacti an advantage over the native flora.
