Research Shows Cold Far More Deadly Than Heat, 10 Times More In Brazil, 20 Times More In South Africa
More warming would save lives
A new, comprehensive Lancet study shows that far more people are being killed globally by cold weather than by hot weather.
Die kalte Sonne here looks at the impacts of temperature extremes on mortality. There’s no doubt that extreme weather kills more people. But the question in these times of “global warming” is whether or not warming is going to lead to more deaths.
A new publication in the renowned journal Lancet, by Burkart et al studied 65 million deaths in 9 countries occurring between Jan 1, 1980, and Dec 31, 2016 in relation to temperature effects.
The researchers found that 17 of the 176 categories for the cause of death “showed J-shaped relationships with daily temperature, whereas the risk of external causes (eg, homicide, suicide, drowning, and related to disasters, mechanical, transport, and other unintentional injuries) increased monotonically with temperature.”
The 17 causes of death with J-shaped curves (dependent of temperature) included heart disease, diabetes, chronic kidney disease, lower respiratory infection, and chronic obstructive pulmonary disease. Using the data, the team of authors extrapolated the results to the entire global population and examined the year 2019.

The authors estimate in 2019, “the average cold-attributable mortality exceeded heat-attributable mortality in all countries for which data were available.” Cold effects were most pronounced in China and in New Zealand.
In China a population attributable fraction (PAF) from cold effects was 4·3% (3·9–4·7) and the attributable rates were 32.0 deaths (27.2–36.8) per 100,000. But when looking at the heat effects in China, the PAF was only 0·4% and the attributable rates were 3·25 deaths per 100 000. In other words, cold death rates were about 10 times higher than heat deaths.
In South Africa, the authors attributed almost 20 times more deaths to cold than to heat (8372 vs 453)!

Cold definitely kills more than heat does by a long shot, and so warming would save lives. The study was sponsored by the Bill and Melinda Gates Foundation.
Are these findings being blared out by the mainstream media? No, of course not. And why not? It’s because they don’t want people to know what’s really going on.
