Is that what they call science now? Speculating about the total number of deaths in the next 84 years? Here are some facts:
“Some 363,500 people die annually from cold, while 43,700 die from excessive heat.” Even if the dooming calculations came true, the deaths from cold will still be considerably higher, and the overall death count lower.
The rest is making things up.
Someone give the news to the jerks at @Ukraine communities.
