We need to protect our health system from Climate-change-doctors

Doctors are at it again trying to scare people about “climate change”. But all around the world, in every study in every city humans die more from the cold than they do from the heat (and by six to 20 times more). That’s thousands of lives and it happens every single year. Don’t these doctors know anything?

Attributable fraction of deaths: Heat, cold and temperature variability together resulted in 42,414 deaths during the study period, accounting for about 6.0% of all deaths. Most of attributable deaths were due to cold (61.4%), and noticeably, contribution from temperature variability [TV] (28.0%) was greater than that from heat (10.6%). Cheng et al.

The awful truth that incompetent self-serving doctors forgot to mention was that cooler room temperatures allow viruses to survive longer, which is just one of many reasons the Flu Season is always worse in winter.

Break my heart, if “climate change” is real the only thing the docs have to worry about is whether they’ll earn less money in winter.

Here’s the headline:

Health system needs to be protected from climate change: doctors

Here’s the real news: The health system needs to be protected from climate-change-doctors. We can’t afford [...]

Airconditioners save 20,000 lives in USA each year

Over the last century there was a remarkable decline in deaths due to hot days and heatwaves. (Not that the media seem keen to say so). Mortality on a hot day declined by fully 75% in the decades after 1960 when air conditioners started to be rolled out.

In the words of the authors from this 2016 study, the people of the US have largely adapted in ways that protect them from extreme heat. The kind of hot days they are talking about happen on average 20 days a year in the US.

There has not been a similar reduction in deaths from cold snaps.

First, we document a remarkable decline in the mortality effect of temperature extremes: The impact of days with a mean temperature exceeding 80°F (26.6C) has declined by about 75 percent over the course of the twentieth century in the United States, with almost the entire decline occurring after 1960. The result is that there are about 20,000 fewer fatalities annually than if the pre-1960 impacts of mortality still prevailed.

We achieved a lot of things in the 20th century, but when Barreca went through the statistics, it wasn’t the introduction of electricity that [...]

As it got hotter in Spain, less people died. Thank air conditioning and electricity.

Cheap energy might save more lives than expensive “climate-changey” energy?

Researchers looked at 47 major cities in Spain, from 1980 to 2015 and checked 554,491 deaths. Even though temperatures have risen, less people are dying of heat in Spain. Apparently human ingenuity, energy and air conditioners were more than able to keep up with climate change. The population is older but less vulnerable to heat now than it was forty years ago.

Air conditioners rose from 5% of the population to 35% during the study period.

Oh the dilemma — to save lives, should we build more windmills to try to change the global climate or aim to get 100% of households access to an air conditioner?

Welcome to the dire threat of climate change:

The relative risk of death fell as temperatures rose (According to the model used). See the caption below.

From the Discussion in the paper:

The temporal evolution of heat-related mortality risks here found is, in general, consistent with those reported by previous studies in some other countries [12–15], which provide evidence for a decrease in vulnerability to climate warming despite the ageing of societies. For example, in Spain, the proportion of people [...]

Deadly winter kills 20,000 more British than usual — if only CO2 caused more warming

The world has record high CO2 levels, which supposedly warms us in winter but apparently not as well as cheap electricity does. As the long winter is set to drag on, Brits are being advised to heat one room as well as they can and live there. This is “progress”…

48,000 Brits dead after worst winter in 42 years

After a brief mild spell, temperatures are set to dip again in April after the chilliest March in 21 years.

It is estimated that 20,275 Brits more than average died between December 1 and March

That includes nearly 5,000 Brits under the age of 65 whose lives may have been cut short.

According to the Office of National Statistics, one in 10 cold weather deaths are among under-65s, one in 10 among 65-75s and eight in 10 among over-75s.

The Department of Health also said cold conditions worsen winter killers including flu, chest diseases, heart attacks, strokes and dementia.

It doesn’t matter where you live — more people die in winter than summer all over the world. It’s not outdoor temperatures that matter — it’s the indoor climate that kills.

Save the world, [...]

Forget extreme temperatures: Nothing kills as many people as moderate cold

Some are scoffing at the idea that rising heating costs will kill people. But check out the number-one temperature-killer in 74 million deaths across 13 countries. It’s not the extremes that we need to worry about, the deadly phrase is “mildly suboptimal temperatures”. Look at the blue finger of death in the graph below, starkly showing how irrelevant “extreme heat”, or any other ambient temperature zone, is.

Do you need an excuse to turn the heater on in winter? Low ambient room temperatures will thicken your blood.

Moderate cold accounted for as many as 6.6% of all deaths. Extreme temperatures (either cold or hot) were responsible for only 0·86%.

Join the dots — will we save more lives by:

a) making homes cold now in the hope that lower “carbon” emissions will,

b) mean less deaths from heat in 90 years time despite people probably having better access to heaters and air conditioners?

Would you sacrifice ten years of your life…

Death, disease, coming in 2050 says model of model

“Half a million deaths by 2050!”

The Lancet study in a nutshell: Take climate models that don’t work, and guesstimate what might happen to agriculture because of the climate we probably won’t get. Then use those guesses of food production in 2050 to fantasize what that means for human mortality. After all, we don’t know how many people are killed today by “4% less fruit and vege and 0.7% less meat”, but we can estimate what that dietary change will do in 2050 after a medical revolution, 35 years of plant breeding and agricultural changes. Not to mention a few more rounds of global food fads and phases of Vegan, Paleo, Atkins, and 5:2 Fasting. (But how did they factor in the mortality effect from another 2,000 episodes of MasterChef?)

Seriously, CO2 has increased crop yields, and will continue to do so until we hit 1000ppm (or maybe 2000). Around the planet, plants grow in warm places, and shrivel up and die in cold ones. So do people. Cold kills 20 times as many people as heat does. It must take a lot of modeling to calculate “more deaths” from two good outcomes.

Look at where fruit grows. [...]
