Climate change could worsen heart deaths linked to extreme temperatures
By Cara Murez, HealthDay News
Both extremely hot and very cold days take their toll on people who have heart disease, particularly those with heart failure.
A new multinational analysis of 32 million heart-related deaths over the past 40 years found more occurred on days with severe temperatures, an issue that climate change could make even worse.
…
The investigators compared heart-related deaths on the hottest and the coldest 2.5% of days in 567 cities with those on days when temperatures were optimal.
For every 1,000 heart-related deaths, there were an additional 2.2 deaths on days with extreme heat. There were also 9.1 additional deaths on days with extreme cold, the findings showed.
Among people with heart failure, there were 2.6 additional deaths on extremely hot days and 12.8 on extremely cold days, the researchers reported.

Abstract
Background: Cardiovascular disease is the leading cause of death worldwide. Existing studies on the association between temperatures and cardiovascular deaths have been limited in geographic zones and have generally considered associations with total cardiovascular deaths rather than cause-specific cardiovascular deaths.
Methods: We used unified data collection protocols within the Multi-Country Multi-City Collaborative Network to assemble a database of daily counts of specific cardiovascular causes of death from 567 cities in 27 countries across 5 continents in overlapping periods ranging from 1979 to 2019. City-specific daily ambient temperatures were obtained from weather stations and climate reanalysis models. To investigate cardiovascular mortality associations with extreme hot and cold temperatures, we fit case-crossover models in each city and then used a mixed-effects meta-analytic framework to pool individual city estimates. Extreme temperature percentiles were compared with the minimum mortality temperature in each location. Excess deaths were calculated for a range of extreme temperature days.
Results: The analyses included deaths from any cardiovascular cause (32 154 935), ischemic heart disease (11 745 880), stroke (9 351 312), heart failure (3 673 723), and arrhythmia (670 859). At extreme temperature percentiles, heat (99th percentile) and cold (1st percentile) were associated with higher risk of dying from any cardiovascular cause, ischemic heart disease, stroke, and heart failure as compared to the minimum mortality temperature, which is the temperature associated with least mortality. Across a range of extreme temperatures, hot days (above 97.5th percentile) and cold days (below 2.5th percentile) accounted for 2.2 (95% empirical CI [eCI], 2.1–2.3) and 9.1 (95% eCI, 8.9–9.2) excess deaths for every 1000 cardiovascular deaths, respectively. Heart failure was associated with the highest excess deaths proportion from extreme hot and cold days with 2.6 (95% eCI, 2.4–2.8) and 12.8 (95% eCI, 12.2–13.1) for every 1000 heart failure deaths, respectively.
Conclusions: Across a large, multinational sample, exposure to extreme hot and cold temperatures was associated with a greater risk of mortality from multiple common cardiovascular conditions. The intersections between extreme temperatures and cardiovascular health need to be thoroughly characterized in the present day—and especially under a changing climate.

Are the doctors seriously suggesting global warming is responsible for cold weather mortality? Also from the paper;
…
Climate change produces both hotter summers and colder winters, rendering populations not accustomed to these unusual weather conditions vulnerable, especially in low-income areas where there may be less adaptability to changing conditions.

Strangely the message from climate scientists used to be that global warming would cause milder winters – hence all those hilarious “end of snow” predictions. Milder winters would have reduced winter mortality, and likely have reduced overall seasonal mortality, given that too cold seems to be worse for our health than too hot.
But that was yesterminute’s settled science.
Now the settled climate consensus appears to be that global warming causes all the bad weather, hot or cold. So when you feel the bitterness of a freezing cold winter, what you are really experiencing is life threatening global warming.

Yet another “Publish or be damned” paper. Many authors listed just to get a paper to put on their CV.
A major snowstorm is developing in the Midwest with winds of up to 60 km/h in gusts.
Years ago a cold spell in Brazil that ruined a coffee crop was blamed on global warming, The explanation was that all the warm air rising in north pulled cold southern air into Brazil.
Climate cooling… warming… change. Undeniable, unfalsifiable.
In past, present, and progressive times, cargo cults would perform human rites for social, redistributive, clinical, political, and fair weather causes.
CO2 causes all bad weather?
That’s what the alarmists say. And they claim it’s going to get worse.
Of course, they have no evidence to prove any of that. But that doesn’t stop them from making the claims.

Well, “duh.”
” Global Warming Induced Colder Winters Could Cause More Heart Attacks ”
Not news. Everyone knows that everything is caused by Global Worming TM.
Real news would be something NOT CAUSED by Global Worming TM.
“For every 1,000 heart-related deaths, there were an additional 2.2 deaths on days with extreme heat. There were also 9.1 additional deaths on days with extreme cold, the findings showed.”
‘the findings showed’ to a linear thinking climateer idiot! Severe winter weather causes much increased response times, increased demand for health services due to accidents, flu season …

Yep, even I can Google the reason and put this study in the garbage.
Are they trying to make us believe that by the very fact that we provide heat globally and uniformly in an environment (AGW hypothesis), we can cool some of its own areas?
Didn’t know that by turning on the oven in the kitchen I could cool the living room : will try next summer.
Climate alarmists are more likely to cause health issues, including those idiotic eco loons that glue themselves to roads blocking ambulances on emergency calls
0.22% more deaths when too hot, 0.91% more deaths when too cold. There’s no way leftist eco nuts could push this as evidence for more CO2 villification, right?
Leftist nut: Hold my beer.
A glance at the list of authors confirms Richard Lindzen’s observation that before the global warming (aka climate change) craze atmospheric physics meteorology and related fields were relatively thinly practiced specializations whereas now there is a surfeit of mediocre practitioners.
Eric, thanks for this timely warning. It was terribly cold when I went for a walk last night ~ 45F. I’ll have to consult with my doctor about this.
They are sure going to see an increase in unexpected heart failure. There is currently a pandemic of “unknown cause of death” sweeping the western world. It may be kinda handy if they can link that to the “climate crisis” too.
He he –
Seriously 45 authors?
The inverse relationship between paper quality and author count is demonstrated once again!
From the article: “Climate change produces both hotter summers and colder winters”
No, [Human-caused] climate change does not produce hotter summers and colder winters. There is no evidence for this. This is an unsubstantiated assertion. This is not science.
Yeah, where was that theory published again?
I would expect that shoveling snow, chopping wood, and pushing stuck cars leads to cold weather heart attacks. Just an alternative thought game.
It seems to me that due to Global Warming, there wouldn’t be any “extreme cold days.” All of them would have been in the past.
One suspects that the source citation for this is from a guardian article or a BBC show or similar fake news source.
“Climate change produces both hotter summers and colder winters”
With no reference for that, I reckon someone at the journal made sure it was in there.
Meanwhile a UK study estimates 56-141 times as many cold related deaths than heat related deaths:

They’re looking for a scapegoat to blame for all the people who Died Suddenly. We know why, and it’s not because of climate change.
